Introduction
Calling the early church fathers “Young Earth Creationists” (YECs) is a bit like calling Aristotle a modern physicist because he wrote about motion — it borrows a familiar word while erasing the very methods, aims, and assumptions that defined those thinkers. Yet in August 2023, Calvin Smith — Executive Director of Answers in Genesis Canada and a prominent public voice for AiG’s apologetics work — released a video responding to Dr. Hugh Ross, an astrophysicist and founder of Reasons to Believe, who argues that many early Christian writers held views compatible with his old‑earth “day‑age” model and that modern Young Earth Creationism is a much more recent development. Smith countered this claim by insisting that figures from Irenaeus to Aquinas and beyond not only rejected Ross’ old-earth views but were themselves “Young Earth Creationists in the most basic sense of the term.” (1)
The move sounds authoritative, but it hinges on a rhetorical shortcut: collapse a modern, highly specific doctrinal system into a few broad phrases, then retroactively apply that label to anyone in antiquity who affirmed divine creation sometime within the last 12,000 years. Once the definition is thinned out enough, nearly every ancient or medieval theologian becomes a “Young Earth Creationist,” even though their actual writings tell a very different story.
That’s where the real issue begins — and where the evidence matters.
Calvin Smith’s claim and AiG’s Narrower Definition
Calvin Smith’s basic four‑point rubric (as presented in his video) reduces the definition of “Young Earth Creationist” to roughly:
Genesis days are literal 24‑hour days.
God created everything ex nihilo, fully formed and functioning.
The earth is about 6,000–10,000 years old.
Noah’s Flood was global.
This is a broad, catch‑all definition that can be read as “anyone who affirms divine creation and a recent chronology.” But AiG’s official doctrinal package is far more specific and doctrinally loaded. (2, 3, 4) AiG’s public statements and statement of faith typically require, among other things:
Six ordinary 24‑hour creation days.
A chronology of roughly 6,000 years based on biblical genealogies and James Ussher’s calculations. (5, 6)
No animal death or suffering before the Fall.
A global Flood that explains most geological features.
A rejection of evolution in any form and a commitment to a literal grammatical‑historical hermeneutic for Genesis.
A historical Adam and Eve as the first humans.
The Bible as the sole and final authority on all matters, including history and science. (7)
As one can see, Smith’s four points omit several of AiG’s non‑negotiable doctrinal commitments (no pre‑Fall animal death; rejection of any evolutionary process; the theological implications AiG draws from a literalist hermeneutic). That omission matters: many historical figures Smith cites affirm some elements (God as Creator) but reject or nuance others (literal 24‑hour days, no pre‑Fall animal death, Flood geology, rigid historical chronology, etc.). If one uses AiG’s full standard, many of the Fathers Calvin cites would be excluded. In fact, if they were to apply for a job at Answers in Genesis, they would not be hired, since AiG requires all staff to affirm its entire statement of faith as a condition of employment — a statement the Fathers themselves could not sign in good conscience.
Philo of Alexandria — Jewish Allegory, Philosophical Cosmology, and an Explicitly Non‑literal Reading of Genesis
In his video, Smith appeals to Josephus as evidence that ancient Jews read Genesis in a straightforward, literal, six‑day manner. And he’s right about Josephus: Josephus does present the creation days as literal days and affirms a recent creation. But Smith never mentions Philo of Alexandria, Josephus’s near‑contemporary and one of the most influential Jewish interpreters of the Second Temple period — a figure whose approach to Genesis is the exact opposite of Josephus’s.
This omission matters because ancient Judaism was not monolithic, just as modern Judaism is not monolithic and modern Christianity is not monolithic.
Second Temple Judaism included:
Literalist interpreters (Josephus is a good example)
Allegorical and philosophical interpreters (Philo is the clearest example)
Sectarian groups with distinctive cosmologies (Essenes/Qumran, though their Genesis hermeneutics are not fully preserved)
Rabbinic trajectories that later developed into midrashic and mystical readings
We do not have enough surviving material to say with confidence what the Essenes or other sects believed about the length of the creation days. The Dead Sea Scrolls contain creation-themed hymns and reflections, but nothing that clearly articulates a literalist or non-literalist stance on Genesis 1. What we can say is that Jewish interpretation in this period was diverse — and Philo represents a major, well‑attested stream of that diversity.
Smith’s appeal to Josephus as if he represents “the Jewish view” is therefore incomplete. Josephus is one Jewish voice. Philo is another — and Philo’s voice directly contradicts the modern YEC hermeneutic.
Philo’s Hermeneutic: Genesis as Symbolic, Philosophical, and Non‑literal
Philo (1st century AD), a Jewish interpreter steeped in Hellenistic philosophy, makes it unmistakably clear that Genesis is not, in his view, a literal, sequential account of material origins. His entire interpretive method is built on the conviction that Moses wrote in an elevated, symbolic style designed to convey philosophical and moral truths rather than scientific or historical detail. As he explains at the opening of On the Creation:
“Moses, in the beginning of his laws, neither declared what ought to be done in a naked and unadorned manner… but made the beginning of his laws entirely beautiful.” — De Opificio Mundi
This is Philo’s hermeneutic in miniature: Genesis is not “naked and unadorned” history but a beautifully constructed philosophical prologue.
Philo then directly addresses the creation “days” and rejects the idea that they are literal temporal units. He argues that God’s creative act is timeless and that the six‑day structure is pedagogical, not chronological:
“It would be a sign of great simplicity to think that the world was created in six days, or indeed in any time at all.” — De Opificio Mundi
He further reinforces this point by insisting that God’s creative act cannot be measured by time:
“The world was created in accordance with the perfect number, not in time; for time is the measure of movement, but the world is the work of God, who is without movement.” — De Opificio Mundi
Philo also interprets the Garden of Eden and its characters allegorically. Eden is not a geographical location but a symbol of divine wisdom; the trees represent virtues; Adam and Eve represent aspects of the human soul:
“The paradise is the wisdom of God… the trees are the virtues.” — Allegorical Interpretation, Book I
“Adam is the mind, and Eve is the senses.” — Allegorical Interpretation, Book II
For Philo, the literal narrative is not the point. Genesis is a philosophical drama about the soul’s relationship to God, virtue, and reason.
Justin Martyr — Typology, Christological Fulfillment, and a Non‑chronological use of Genesis
Justin Martyr (mid‑2nd century AD) makes his interpretive method explicit: the events of the Old Testament are types that point forward to Christ. His reading of Genesis is therefore theological and Christological, not chronological or scientific. As he states in Dialogue with Trypho:
“The events of the past were types of the things to come.” — Dialogue with Trypho
This is Justin’s hermeneutic in miniature. Scripture’s purpose is to reveal Christ and to provide moral instruction, not to supply a scientific account of origins. He reinforces this when he writes:
“We assert that the prophets spoke of the things which were to be.” — Dialogue with Trypho
Justin’s use of Genesis follows this method. When he cites the creation narrative, he does so to argue that Christ is the pre‑existent Logos through whom God made the world. For example, he uses Genesis 1:26 (“Let us make man…”) to argue for Christ’s pre‑existence:
“We have been taught that Christ is the first‑begotten of God… the Word of whom every race of men were partakers.” — First Apology, ch. 46
Here, Genesis is a proof‑text for Christology, not a scientific timeline.
Justin also uses Genesis typologically to explain the Fall, the incarnation, and the moral condition of humanity. Adam is a type of Christ; Eve is a type of the Church; the serpent is a type of Satan. Nowhere does Justin attempt to calculate the age of the earth, defend a literal six‑day creation, or construct a geological model of the Flood.
Justin’s use of the “Thousand‑Years-As-a-Day” Principle
Justin does reference Psalm 90:4 and 2 Peter 3:8 (“a day is as a thousand years to the Lord”), but he applies it only to explain why Adam died “in the day” he ate of the fruit:
“For as Adam was told that in the day he ate of the tree he would die, we know he did not live a thousand years.” — Dialogue with Trypho, ch. 81
This interpretive move appears elsewhere in early Christian thought — Irenaeus will later use the same principle — but Justin keeps it narrowly focused on Adam’s death. He never applies it to the six days of creation, never uses it to construct a chronology, and never treats it as a key to the age of the world.
His method remains typological and theological, not temporal.
Irenaeus of Lyons — Salvation History, Recapitulation, and a Literal 1,000‑Years‑Per‑Day Reading of the Creation Week
Irenaeus (late 2nd century AD) reads Genesis through the lens of salvation history and recapitulation—the idea that Christ re‑enacts and reverses the story of Adam. His interpretive method is theological and pastoral, not scientific. He writes:
“God made man in a state of innocence, and endowed him with the power of free will, that he might be able to obey or disobey.” — Against Heresies, Book 3
For Irenaeus, Genesis is the opening act of the drama of redemption. Adam, Eve, and the serpent are read typologically: Adam as a type of Christ, Eve as a type of Mary, and the Garden narrative as the beginning of God’s restorative plan.
Irenaeus and the “Thousand‑Years‑As‑a‑Day” Principle — Applied Directly to the Creation Days
Like Justin before him, Irenaeus points to Psalm 90:4 and 2 Peter 3:8 (“a day is as a thousand years to the Lord”) to explain how Adam could die “in the day” he ate of the fruit while at the same time living to be 930. But Irenaeus goes further: he explicitly applies the principle to the six days of creation.
In Against Heresies 5.23.2, he develops this argument at length. He insists that God’s warning must be true, rejects the Gnostic claim that God lied, and argues that Adam really did die “in the day” he ate — because that “day” is both the sixth day of creation and a thousand‑year period.
He states the point plainly:
“Now in this same day that they [Adam and Eve] ate, in that also did they die… for it is one day of the creation… He died on the same day in which he ate… the sixth day of the creation.” — Against Heresies 5.23.2
Irenaeus then acknowledges the thousand‑year interpretation directly, presenting it as another legitimate way of understanding the same truth:
“There are some… who relegate the death of Adam to the thousandth year; for since a day of the Lord is as a thousand years… he did not overstep the thousand years, but died within them.” — Against Heresies 5.23.2
For Irenaeus, these are not competing interpretations but complementary ones. Adam died “on the sixth day” because the sixth day is a thousand‑year span. This logic becomes the foundation for his well‑known six‑thousand‑year schema:
“For in as many days as this world was made, in so many thousand years shall it be concluded. For the day of the Lord is as a thousand years; and in six days created things were completed. It is evident, therefore, that they will come to an end in the six thousandth year.
And again, since God said to Adam, ‘In the day that you eat of it, you shall die,’ we understand that he did not complete a thousand years. For he died in the nine hundredth and thirtieth year of his life.” — Against Heresies 5.28.3
These passages show Irenaeus’s logic step by step:
1. Adam died “in the day” he ate the fruit.
2. Adam lived 930 years.
3. Therefore, “the day of the Lord is as a thousand years.”
4. Therefore, each creation day corresponds to a thousand years.
5. Therefore, the six days of creation correspond to six thousand years of history.
6. Therefore, the seventh day corresponds to the millennial rest.
This is not symbolic in the modern sense. Irenaeus is making a literal interpretive claim:
Each creation day = 1,000 years
Six creation days = 6,000 years of human history
The seventh day = the millennial rest
Notably, this is the only place in the early church where someone explicitly interprets the creation days as 1,000‑year periods. But — and this is crucial — Irenaeus is not doing geology or cosmology. He is constructing a theological and eschatological pattern, not a scientific timeline for the age of the universe. His “six days = six thousand years” is a redemptive‑historical schema, not a literalist scientific reading of Genesis 1.
Origen of Alexandria — Multiple Senses of Scripture, Explicit Non‑literalism, and a Spiritual Reading of Genesis
Origen (early 3rd century AD) is the first Christian thinker to articulate a formal doctrine of multiple senses of Scripture—literal, moral, and spiritual. He is also the earliest major figure to explicitly reject a strictly literal reading of Genesis when the literal sense would mislead or obscure the deeper meaning of the text.
He states his method plainly:
“We must not suppose that everything is to be taken in the literal sense; for the spiritual meaning is often more important.” — On First Principles (De Principiis)
For Origen, the literal sense is often the lowest sense, suitable for beginners but insufficient for mature theological understanding. He argues that God intentionally included passages in Scripture that cannot be taken literally so that readers would be driven to seek the spiritual meaning.
He writes:
“Who is so foolish as to suppose that God planted a paradise in Eden in the east, and placed in it a tree of life… so that anyone who tasted its fruit with his bodily teeth would gain life?” — On First Principles 4.1.16
This is not a rhetorical flourish. It is Origen’s explicit claim that the Garden of Eden narrative cannot be read literally without falling into absurdity.
Origen’s Interpretation of Genesis: Spiritual, Symbolic, and Non‑chronological
Origen applies this method consistently to Genesis:
The Garden is a spiritual reality, not a geographical location.
The trees represent spiritual truths, not botanical specimens.
The serpent symbolizes the devil’s temptation, not a literal talking animal.
The creation days are not temporal units but a pedagogical structure revealing the order of God’s creative wisdom.
He writes:
“What man of intelligence will believe that the first, second, and third day existed without the sun, moon, and stars?” — On First Principles 4.1.16
This is one of the clearest early Christian rejections of a literal six‑day creation. Origen is not attacking Scripture — he is defending it from what he sees as naïve readings that bring the text into disrepute.
For Origen, Genesis is a spiritual cosmology, not a scientific chronology.
Basil of Caesarea — Homiletic Theology, Liturgical Exposition, and a Non‑scientific Reading of Genesis
Basil of Caesarea (4th century AD) is best known for his Hexaemeron, a series of nine homilies on the six days of creation. These sermons are pastoral, liturgical, and theological, not scientific or chronological. Basil’s aim is to edify his congregation, not to construct a literalist cosmology or a scientific account of origins.
He opens the first homily by framing Genesis as a theological revelation of God’s creative power:
“I am about to speak of the creation of heaven and earth… which drew its origin from God.” — Hexaemeron, Homily I
Basil’s concern is to proclaim God as Creator and to draw moral and spiritual lessons from the order of creation. He is not attempting to calculate the age of the earth, defend a literal six‑day chronology, or explain the mechanics of creation in scientific terms.
Basil’s Method: Theological Contemplation, Not Literalist Exegesis
Throughout the Hexaemeron, Basil emphasizes that the purpose of Genesis is to reveal God’s wisdom and providence. He repeatedly warns his hearers not to become entangled in speculative questions about the physical details of creation:
“Do not let us seek to penetrate the essence of things… it is enough for us to know that God created.” — Hexaemeron, Homily I
This is a methodological statement. Basil is telling his audience that Genesis is not a scientific treatise and that Christians should not attempt to extract physical or cosmological mechanics from it.
He also insists that the creation narrative is written for moral and spiritual instruction, not for scientific explanation:
“Moses did not intend to teach us by what means the universe was brought into order, but to lead us to the knowledge of the Creator.” — Hexaemeron, Homily I.10
Basil’s approach is contemplative and pastoral. He uses the creation days as a liturgical and theological structure for preaching, not as a scientific timeline.
Basil’s Interpretation of the Creation Days
Basil does treat the creation days as “days,” but he does so homiletically, not scientifically. He never argues that they are 24‑hour periods, nor does he attempt to defend such a view against alternatives. His interest is in the order of creation, not the duration of creation.
For example, when discussing the first day, Basil focuses on the theological significance of light, not on the mechanics of how light existed before the sun:
“The command was given, and immediately the world was formed… The light was created first to show forth the beauty of the universe.” — Hexaemeron, Homily II
He does not attempt to reconcile this with astronomy or physics. He simply draws out the spiritual meaning.
Likewise, when discussing the creation of plants before the sun, Basil does not treat this as a scientific puzzle but as a theological truth about God’s ordering of creation:
“The earth received the command to bring forth plants before the sun was created, so that you might learn that it is not the sun that makes plants grow, but the Word of God.” — Hexaemeron, Homily V
This is a theological argument, not a scientific one.
Augustine of Hippo — instantaneous creation, seminal seeds, and a developmental view of life incompatible with AiG’s “fixed kinds” model
Augustine (late 4th–early 5th century AD) is one of the most influential Christian interpreters of Genesis, and he is also one of the most explicit ancient critics of a literal, sequential, six‑day creation. His method is theological, philosophical, and deeply concerned with avoiding interpretations that bring Scripture into disrepute.
He states his hermeneutic plainly:
“In matters that are obscure and far beyond our vision… different interpretations are sometimes possible without prejudice to the faith.” — The Literal Meaning of Genesis (De Genesi ad Litteram)
This is Augustine’s way of saying: Genesis is not always meant to be read literally, and Christians must avoid dogmatic claims about passages that exceed human understanding.
Augustine’s Doctrine of Instantaneous Creation
Augustine explicitly rejects the idea that God created the world through six sequential 24‑hour days. Instead, he argues that God created everything simultaneously, and that the six‑day structure is a literary device for human understanding.
He writes:
“God created all things at once, and not by successive acts.” — De Genesi ad Litteram
And again:
“God created all things together in the beginning.” — City of God, XI.9
For Augustine, the “days” of Genesis are not temporal units but a way of ordering creation theologically.
This alone places Augustine outside AiG’s hermeneutic, which requires six literal 24‑hour days.
Augustine on Biblical Genealogies and the Age of the World
Augustine does affirm a broadly “recent” creation, since he accepts the biblical genealogies as historically meaningful. Like most ancient Jews and Christians, he believed the world was created “not many thousands of years ago.”
But Augustine is equally clear that:
I. The exact age of the world is unknown.
He explicitly states:
“Nor can we determine the exact number of years since creation.” — City of God XII.10
And warns:
“We must be cautious in affirming anything on this subject, lest we make rash assertions about matters of such obscurity.” — City of God XVIII.40
He reiterates:
“We should not presume to determine the number of years that have passed since the beginning.” — De Genesi ad Litteram V.5.12
II. Augustine rejects the idea that Genesis provides a precise scientific chronology.
He accepts the genealogies as part of sacred history, but he does not treat them as a tool for calculating the earth’s age with precision — and he explicitly warns Christians not to do so.
Augustine’s Doctrine of Rationes Seminales (Seminal Seeds) — A View that Allows New Forms of Life to Emerge Over Time
Augustine also teaches that God implanted “seminal principles” (rationes seminales) into creation — hidden potentialities that unfold over time. This is one of the earliest Christian articulations of developmental creation, a view that allows for new forms of life to emerge long after the initial creative act.
He writes:
“He implanted in them certain rationes seminales (seed‑principles) by which they would be developed.” — City of God, XI.22
And again:
“The earth received the seeds of all things which were to come forth in their due time.” — De Genesi ad Litteram
This is not evolution in the modern sense, but it is unmistakably a doctrine of:
Latent potentiality.
Development.
Emergence.
The appearance of new forms over time.
This is where Augustine Diverges Sharply from AiG.
AiG teaches:
God created original “created kinds” (baramins) during the creation week.
These kinds contain built‑in genetic potential for variation.
But no new kinds can emerge after Day 6.
All diversification is variation within a kind, not the appearance of new kinds.
Augustine’s view is fundamentally different:
He does not speak of fixed “kinds.”
He does not limit development to variation within a kind.
He explicitly teaches that new forms of life can emerge from latent potentialities implanted at creation.
He sees creation as dynamic, not fixed.
In other words, Augustine’s view is proto‑developmental, not proto‑YEC.
Augustine on Animal Mortality — A Created Order That Includes Death
Another major point where Augustine diverges sharply from AiG is his teaching on animal mortality. Augustine is explicit: non‑human creatures were created mortal, and their death is not a consequence of Adam’s sin. For him, the Fall introduces spiritual and physical death for humans, but it does not alter the biological nature of animals or the structure of the natural world.
Augustine writes that animals “were not made immortal like man” and that their death is part of the natural order God established from the beginning. In City of God, Augustine argues that the mortality of animals is not a defect or a punishment but simply the condition appropriate to their nature (XII.4–6). Their cycles of generation and corruption belong to the goodness of creation itself.
This view stands in direct tension with AiG’s system, which requires a death‑free creation prior to Adam’s sin. AiG teaches that:
- No animal died before the Fall.
- Predation, decay, and natural cycles are the result of human sin.
- The fossil record must therefore be explained by the Flood, not by ordinary history.
Augustine rejects this entire framework. For him:
- Animal death is not evil.
- It is not a theological problem needing explanation.
- It is not tied to human sin.
- It does not threaten the goodness of creation.
This is not a minor disagreement. It strikes at the core of AiG’s theological architecture. If animals were always mortal, then the “perfect death‑free world” central to modern YECism never existed. The Fall does not introduce biological entropy into the animal world, and the fossil record does not require a catastrophic global flood to account for pre‑fall death. Augustine’s view is consistent with his broader developmental understanding of creation: a world in which life unfolds, changes, and passes away according to the natural order God established.
In short, Augustine’s doctrine of animal mortality is yet another decisive point where his theology cannot be reconciled with AiG’s model.
Augustine’s Warnings Against Naïve Literalism
Augustine repeatedly warns Christians not to cling to literal interpretations of Genesis that contradict reason or observable reality:
“Usually, even a non-Christian knows something about the earth, the heavens, and the other elements of the world, about the motion and orbit of the stars and even their size and relative positions, about the predictable eclipses of the sun and moon, the cycles of the years and the seasons, about the kinds of animals, shrubs, stones, and so forth, and this knowledge he holds to as being certain from reason and experience. Now, it is a disgraceful and dangerous thing for an infidel to hear a Christian, presumably giving the meaning of Holy Scripture, talking nonsense on these topics; and we should take all means to prevent such an embarrassing situation, in which people show up vast ignorance in a Christian and laugh it to scorn. The shame is not so much that an ignorant individual is derided, but that people outside the household of faith think our sacred writers held such opinions, and, to the great loss of those for whose salvation we toil, the writers of our Scripture are criticized and rejected as unlearned men. If they find a Christian mistaken in a field which they themselves know well and hear him maintaining his foolish opinions about our books, how are they going to believe those books in matters concerning the resurrection of the dead, the hope of eternal life, and the kingdom of heaven, when they think their pages are full of falsehoods on facts which they themselves have learnt from experience and the light of reason? Reckless and incompetent expounders of Holy Scripture bring untold trouble and sorrow on their wiser brethren when they are caught in one of their mischievous false opinions and are taken to task by those who are not bound by the authority of our sacred books. For then, to defend their utterly foolish and obviously untrue statements, they will try to call upon Holy Scripture for proof and even recite from memory many passages which they think support their position, although they understand neither what they say nor the things about which they make assertion [quoting 1 Timothy 1:7].” — De Genesi ad Litteram, I.19.39
For Augustine, the danger is not simply intellectual embarrassment. It is theological harm: when Christians insist that Scripture teaches things plainly disproven by experience or reason, they make the faith itself appear foolish. Augustine’s point is unmistakable — Christians must not treat Scripture as a scientific manual, nor force literal readings where the text does not demand them.
This is where Augustine’s warning stands in direct tension with the modern biblicist posture exemplified by Answers in Genesis. AiG teaches that the Bible functions as the sole and final authority on all matters — including scientific questions about the age of the earth, geology, cosmology, and biology — and therefore scientific inquiry must be filtered through a literal reading of Genesis 1-11. In this model, Scripture becomes the controlling authority for what is and is not scientifically true
Augustine rejects precisely this approach. He insists that when Scripture appears to conflict with what “reason and experience” have established, Christians must reconsider their interpretation — not dismiss the evidence. For him, biblical authority does not require treating Genesis as a scientific text, nor does it require defending literal readings that bring Scripture into disrepute.
In other words:
AiG’s model treats Scripture as the controlling authority for scientific claims.
Augustine treats Scripture as the controlling authority for theological claims — and warns Christians not to misuse it in scientific domains.
Augustine’s hermeneutic is not a retreat from biblical authority; it is a defense of it. He believes Scripture is too important to be tied to interpretations that collapse under the weight of observable reality. His concern is pastoral and evangelistic: misreading Scripture in scientific matters undermines trust in Scripture in spiritual matters.
This is not a minor difference. It is a fundamentally different understanding of what biblical authority is and how it should function.
Thomas Aquinas — Scholastic Synthesis, Natural Processes, and a Doctrine of Creation that Welcomes Interpretive Diversity
Thomas Aquinas (13th century AD) represents the high point of medieval scholastic theology. His reading of Genesis is shaped by a synthesis of Christian doctrine with Aristotelian natural philosophy. Aquinas is deeply committed to the idea that God works through secondary causes — that is, through the natural processes He Himself created.
He writes:
“God works in every worker, but so that things have their own proper operations.” — Summa Theologiae I.105.5
This principle governs Aquinas’s entire approach to creation: God is the First Cause, but creatures genuinely act according to their natures.
Aquinas on Interpretive Diversity: Multiple Readings of Genesis are Legitimate
One of the most important — and most overlooked — aspects of Aquinas’s theology is his explicit affirmation that Christians may legitimately disagree about how to interpret the details of Genesis, because the mode and order of creation are not matters essential to the faith.
Aquinas states this with remarkable clarity:
“With respect to the beginning of the world something pertains to the substance of faith, namely that the world began to be by creation, and all the saints agree in this. But how and in what order this was done pertains to faith only indirectly insofar as it is treated by Scripture, the truth of which the saints save in the different explanations they offer. Hence Augustine says that what is stated in Genesis about the creation of the world is not written to teach us these things, which are of no use for salvation.” — Commentary on the Sentences, Book II, Distinction 12, Article 2, Q. 6
This is devastating to AiG’s claim that:
Only the YEC interpretation is biblical.
All other interpretations are “compromise.”
Differing views on Genesis are capitulation to “man’s fallible ideas.”
Aquinas says the opposite:
The fact of creation is essential.
The manner and order of creation are open to multiple legitimate interpretations.
Genesis is not meant to teach us about scientific matters which are of no use for salvation.
This is not a marginal comment — it is Aquinas’s official teaching.
Aquinas on Genesis: Theological Order, Not Scientific Literalism
Aquinas reads Genesis as a theological account of God’s creative act, not as a scientific description of the mechanics of creation. He affirms that Scripture often speaks phenomenologically — according to appearances — rather than with scientific precision:
“The words of Scripture are accommodated to the understanding of the common people.” — Summa Theologiae I.1.9 ad 3
He is not concerned with the age of the earth, the mechanics of the creation days, or the scientific details of cosmology. His interest is metaphysical and theological: how God’s creative act establishes the order of nature.
Aquinas on Animal Death: Natural, Not the Result of the Fall
Aquinas explicitly teaches that animal death is natural and not the result of Adam’s sin.
He writes:
“Human death is the penalty of sin; the death of irrational animals is not of the same kind.” — Summa Theologiae I.96.1 ad 2
And:
“The life of animals and plants is preserved by the destruction of others.” — Summa Contra Gentiles III.112
For Aquinas, predation, decay, and animal mortality are built into the natural order. They are not the result of the Fall and not a corruption of creation.
This directly contradicts AiG’s doctrine that:
No animal death occurred before the Fall.
Predation is a result of human sin.
The original creation was completely perfect and free of all forms of suffering and death.
Aquinas’s view is the opposite: animal death is natural, good, and part of God’s design.
Aquinas on “Kinds” and Natural Processes
As stated previously, AiG teaches that God created fixed “kinds” during the creation week, and that all post‑creation speciation is merely genetic variation within those kinds. Aquinas, however, does not operate with a baraminological framework. Instead, he affirms:
Real natural processes.
Real causal powers in creatures.
Real development within nature.
Real emergence of new forms through secondary causes.
He writes:
“God grants to created things the dignity of causing.” — Summa Theologiae I.22.3
This means that creatures can bring about real effects — including the emergence of new forms — through the natural powers God gave them.
Aquinas’s metaphysics is dynamic, not static. Nature is not a closed system of fixed “created kinds” but a hierarchy of real causal powers.
Why the Fathers Do Not Fit AiG’s YEC Box
Across these authors — Jewish, patristic, and medieval — we find recurring themes that contradict AiG’s modern doctrinal package:
Allegorical, typological, and spiritual hermeneutics (Philo, Origen, Justin, Basil) rather than a single literalist method.
Rejection of a biblicist “Bible‑as‑science‑textbook” model of authority — Augustine in particular warns that Christians must not treat Genesis as a source of scientific claims or defend literal interpretations that contradict reason and observable reality. This stands in direct opposition to AiG’s insistence that scientific questions must be answered through a literal reading of Scripture.
Non‑literal creation days, including explicitly symbolic or pedagogical days (Philo, Origen, Augustine) and even thousand‑year days (Irenaeus).
Instantaneous creation rather than six sequential days (Augustine).
Theological and soteriological priorities (Justin, Irenaeus) rather than geological or biological apologetics.
Conceptual openness to secondary causes and developmental principles (Augustine’s rationes seminales; Aquinas’s doctrine of secondary causation).
Acceptance of natural animal death before the Fall (Augustine, Aquinas).
No uniform, binding numeric chronology that maps onto AiG’s narrow 6,000‑year claim (hence the range from 6,000-10,000 years).
No systematic Flood geology resembling AiG’s modern attempt to explain strata and fossils.
Diverse Jewish interpretations even in the Second Temple period (Josephus literal; Philo non‑literal; Essene views unknown).
In short: the Fathers (and their Jewish predecessors) affirmed that God created — but they did not affirm the modern, tightly specified, doctrinally loaded package AiG requires of a “Young Earth Creationist.” Their readings of Genesis differ not only from AiG’s conclusions but from AiG’s entire hermeneutical posture.
The Rhetorical and Logical Problem in Smith’s Move
Smith’s strategy performs two incompatible moves at once:
I. Internally narrow standard
Within AiG, “biblical creationist” is defined by a strict doctrinal package:
Consecutive creative acts over six, literal, 24‑hour days.
A 6,000‑10,000 year chronology.
No animal death before the Fall.
Flood geology.
Rejection of evolution beyond variation within “kinds.”
A literalist hermeneutic as the only faithful option.
II. Externally expansive labeling
When appealing to historical authority, Smith expands the label “Young Earth Creationist” to include virtually anyone who affirms divine creation or ever taught that the earth was 6,000-10,000 years old — even when those figures explicitly reject or nuance AiG’s non‑negotiables.
These two moves cannot be reconciled.
If AiG’s internal standard is the correct definition of YEC, then most of the Fathers Smith cites would be excluded. If, instead, Smith’s broad external definition is used to include the Fathers, then AiG’s internal standard is being abandoned — and the label “YEC” becomes so broad as to be meaningless.
Logical Fallacies and Rhetorical Tactics at Work
Equivocation
Using “Young Earth Creationist” in two incompatible senses — a narrow doctrinal package internally, and a broad affirmation of creation externally. When speaking of modern Christians, AiG requires literal 24‑hour days, fixed kinds, no animal death before the Fall, a 6,000‑year chronology, and Flood geology. But when speaking of the Fathers, Smith uses a far looser definition that requires none of these things.
Anachronism
Projecting modern scientific debates and doctrinal boundaries onto pre‑modern thinkers who did not share those categories. Ancient interpreters — Christian, Jewish, and Pagan alike — simply did not think in terms of “billions of years” “evolution” or “Young Earth Creationism.” Those are modern frameworks shaped by post‑Enlightenment science.
Pagan philosophers typically assumed an eternal or cyclically renewed cosmos, not a universe measured in billions of years or evolutionary terms. Jewish and early Christian writers, by contrast, assumed a divinely created world within human memory, but they did not operate with anything like AiG’s modern chronology, hermeneutics, or scientific concerns.
This is why projecting old‑earth views onto the Fathers is just as anachronistic as claiming they affirmed modern YECism. Both moves impose contemporary categories onto ancient thinkers who were asking different questions, using different interpretive methods, and working within different intellectual worlds.
And here Smith is right about one thing: if an old‑earth interpreter claims that “most or all of the Fathers held non‑literal views,” that too would be anachronistic. The Fathers were diverse, not uniformly allegorical or uniformly literal. The problem is not which side one takes — it is the method of retrojecting modern debates into antiquity.
Selective Criteria (A Refined Form of Cherry‑picking)
Smith does not merely select quotations; he selects which criteria count as “Young Earth Creationism.” He constructs a broad, four‑point definition that is loose enough for almost any ancient author to satisfy partially, even though these points do not match AiG’s own doctrinal standard. He then highlights where each Father affirms one or two of these points while ignoring the many ways they diverge from AiG’s actual YEC framework.
This is a form of cherry‑picking by category construction rather than by quotation: the criteria are chosen to produce the desired conclusion.
A related pattern appears in his treatment of Augustine. Smith cites Augustine where he affirms the genealogies and a broadly “recent” creation, but he omits Augustine’s equally explicit insistence that the exact age of the world cannot be determined from Scripture and should not be treated dogmatically. By presenting only the parts of Augustine that sound compatible with AiG’s modern chronology while ignoring the parts that reject chronological precision, Smith obscures Augustine’s actual position.
It is true, as Smith notes, that some old‑earth interpreters make the opposite mistake — treating the Fathers’ disagreements with modern YEC as if they were endorsing modern old‑earth views. And if someone claimed that “most of the Fathers held non‑literal views,” Smith would be right to challenge that. But this only reinforces the larger point: both errors arise from the same methodological flaw. Projecting modern categories backward distorts the historical record, regardless of which side is doing it.
False Equivalence
Treating “God created” as equivalent to endorsing AiG’s entire modern doctrinal system. Affirming creation ex nihilo or a historical Adam does not entail agreement with literal days, fixed kinds, Flood geology, or a 6,000‑year chronology.
Special Pleading
Smith and AiG apply strict standards to contemporary Christians—branding them “compromisers” who cave to secular pressure and embrace “man’s pagan religion of evolution and millions of years” rather than God and His Word—while extending far looser, more charitable standards to the historical figures they want to enlist. Modern Christians must affirm AiG’s entire doctrinal package to qualify as having a “biblical worldview,” whereas ancient Christians need only check a few broad boxes to be welcomed into the YEC camp with open arms.
Practical Contradiction
By AiG’s own internal criteria, many of the Fathers Smith cites would themselves be “compromisers.” If Smith were consistent, he would have to apply the same label to them. Instead, he selectively co‑opts them into his cause.
This contradiction becomes clearest in his closing claim that “98% of the Fathers” affirmed Young Earth Creationism, with the remaining 2% also affirming a young earth albeit while promoting instantaneous creation rather than creation over six, 24-hour days. That statistic is produced entirely by his redefinition of YEC. By using a broad, minimal definition for ancient authors and a narrow, doctrinally dense definition for modern Christians, he manufactures a numerical consensus that disappears the moment AiG’s actual criteria are applied.
Smith then accuses old‑earth interpreters of committing an appeal‑to‑authority fallacy — even as he appeals to the Fathers’ authority to support a doctrinal framework they would not recognize. The issue is not the Fathers’ authority but the categories being imposed on them.
Motive Attribution and Conspiratorial Framing
Smith concludes by claiming that organizations who argue the Fathers were not Young Earth Creationists have been “fact‑checked,” “shown to be demonstrably false,” and are now changing their narrative because they know they would be lying if they didn’t. This move shifts the discussion from evidence to motive: disagreement is framed not as a difference in historical interpretation but as deliberate deception. Yet this accusation rests entirely on Smith’s own redefinition of “Young Earth Creationism” and his selective use of the Fathers. Once his criteria are examined, the charge collapses. His framing therefore functions less as historical analysis and more as a rhetorical strategy that treats disagreement as dishonesty — a pattern common in conspiracy‑style reasoning, where opponents are presumed to “know the truth” but hide it for ideological reasons.
On Evidence Selection and Omission
Smith’s video is rhetorically effective because it curates evidence: it highlights statements that can be read as compatible with modern Young Earth Creationism while omitting or downplaying passages where the same authors qualify, allegorize, or explicitly reject AiG’d literalist readings and doctrinal claims.
A historically responsible account must present the full context:
Where an author affirms creation ex nihilo or the chronology of creation.
Where the same author interprets Genesis allegorically or symbolically.
Where they discuss the nature of time.
Where they articulate theological priorities that differ from modern scientific concerns.
Where they explicitly reject the hermeneutical and doctrinal assumptions AiG treats as non-negotiable.
Without this context, the result is not history but selective reconstruction.
Conclusion
Smith’s claim that the Fathers were “Young Earth Creationists” collapses under scrutiny because it conflates terminology with substance. The Fathers often affirmed divine creation, but they did so within hermeneutical, philosophical, and theological frameworks that are not the same as AiG’s modern, doctrinally specific YEC package. Smith’s rhetorical strategy — narrowing the modern standard internally while expanding the label historically — is logically inconsistent and historically misleading. It borrows authority from ancient voices while erasing the very interpretive methods and theological nuances that would disqualify those voices under AiG’s own criteria.
If the goal is historical accuracy, the responsible move is to acknowledge the diversity of ancient Jewish, patristic, and medieval thought about Genesis and to stop treating the label “Young Earth Creationist” as a timeless category that can be applied without regard to context, method, and doctrinal content. The truth is that both modern Young‑Earth and Old‑Earth interpreters sometimes try to enlist the Fathers for their side, but the Fathers simply do not map onto either modern category. They affirmed creation, but not the scientific frameworks of today’s debates. To pretend otherwise is not history — it is rhetorical spin. More than that, it is a contradiction. And as Calvin Smith himself has said: “Contradictions are called lies” and people who “knowingly communicate contradictory information to you, they are in fact, lying.” (8, 9)
At the same time, Smith also insists that “misrepresenting the facts is entirely unbefitting a professing Christian.” On this point, he is right. But that standard must apply consistently. It is telling that he closes his video by quoting both 1 Timothy 6:3–5 and 2 Timothy 4:3–4 — passages about false teachers, corrupt motives, and people who turn away from the truth to follow myths. Placing these texts immediately after accusing Hugh Ross of either incompetence or deliberate deception frames the disagreement not as a matter of historical interpretation but as a matter of spiritual fidelity. Yet this framing becomes self‑indicting when the same selective methods he condemns are evident throughout his own presentation. If these verses are to function as a standard, they must apply to all of us equally. When a presentation relies on redefined categories, selective omission, ambiguity, and conclusions that collapse under engagement with the primary sources, the contradiction becomes unavoidable. The very principle Smith invokes becomes the measure by which his own argument must be judged (Matthew 7:1-3).
All that to say, one thing Smith and I agree on is that when a ministry or teacher claims to defend the truth but relies on contradictions or selective presentation to do so, that should raise serious red flags for Christians who care about integrity. The truth does not need to be protected by distortion. If we are called to love the truth, then we are also called to test what we are being taught — even when it comes from voices we generally agree with. Discernment is not disloyalty; it is obedience. Christians should therefore examine claims carefully, compare them with Scripture and history, and refuse to assume that every confident assertion is a faithful one.
Humans are fallible. We all make mistakes, and when we do, we should be willing to correct them. But when the same errors are repeated and presented as fact even after they’ve been addressed, the issue stops looking like simple misunderstanding and starts looking like a refusal to engage with the truth.
