On the Flesh of Christ

Tertullian's c. 206 'De Carne Christi' — Christological treatise against the Gnostics on Christ's real flesh

Quintus Septimius Florens Tertullianus · c. 206 · Latin · Polemical-theological treatise

Tradition: North African Latin patristics / proto-orthodox Christology / anti-Gnostic polemic

Tertullian's c. 206 'De Carne Christi' — anti-Docetic, anti-Gnostic affirmation of Christ's real flesh; 'credo quia absurdum'

Composed c. 206 at Carthage during Tertullian's mature Montanist period, 'De Carne Christi' (On the Flesh of Christ) is his Christological reply to the Marcionites, Valentinian Gnostics, and the Apellesians — all of whom denied or qualified the reality of Christ's human flesh. The treatise's central question: did the Incarnate Word take real human flesh, born of a real mother, or was the flesh of Christ merely apparent (Docetism), only celestial (some Gnostic versions), or only spiritual-substantial (Apelles's compromise)? Tertullian defends the full, ordinary, blood-and-bone flesh of Christ against Docetic and Gnostic alternatives, drawing on Scripture (especially the Gospel infancy narratives, which Tertullian reads as deliberately physical), philosophical-physical argument (the Stoic theory of corporeality applied to the Incarnation), and ridicule. The treatise contains Tertullian's most-quoted paradox: 'And the Son of God died: it is wholly credible (prorsus credibile est) because it is unfitting (ineptum); and, buried, He rose again: it is certain (certum est) because it is impossible (impossibile)' (De Carne Christi 5.4). This is the locus classicus from which Augustine, then medieval-scholastic theologians, then Kierkegaard would draw the paradoxical-faith tradition; the paraphrase 'credo quia absurdum' (which Tertullian himself never writes) became attached to Tertullian in subsequent reception. The treatise's anti-Docetic insistence on the reality of Christ's flesh was foundational for Latin Christology.

Internal Tensions

Source of the 'credo quia absurdum' paraphrase; defining patristic Latin anti-Docetic / anti-Gnostic Christology. The paradox-formulation has been continuously productive in Christian theology: Augustine inherits it; the medieval scholastics worry it; Kierkegaard makes it the centrepiece of his Philosophical Fragments (1844) reading of the Incarnation as paradox; contemporary analytic philosophy of religion (Stump, Kretzmann) engages it as a question about the logic of incarnational doctrine.

I. Time

c. 206. Tertullian was in his mid-50s, by this point a committed Montanist (though the relationship between his Montanist commitments and his proto-orthodox theological positions remains scholarly debated).

Do you really choose?
If the brain is a physical system and physical systems are governed by laws, then every choice is also a chain of causes — which raises the question of what was really left to choose.
Choice is real within a determined order — agency and determinism aren’t opposites.
On this view, the future is determined and you are genuinely choosing. Those aren't contradictory because the determination runs through you rather than around you: your reasoning, deliberation, and assent are the way the determined outcome gets settled. Choice is what it feels like from …
Roads not taken The future is open and you are a genuine origin of it. (69%) · Choice is structural illusion — every event is fixed by the prior state. (10%) · Even if the universe is undetermined, you are not the chooser. (6%)

Are addicts responsible for their addiction?
Addiction looks from one angle like the textbook case of agency failing — a person doing what they don't, in any meaningful sense, want to do. From another angle it looks like agency at work in hard conditions. Which it is depends on what agency is.
The addict is genuinely responsible within a determined order.
On this view, the addict is acting within a determined order but is genuinely acting — making decisions, endorsing or resisting urges, seeking or refusing help. Responsibility attaches not because some uncaused choice happened, but because the addict is the kind of agent through which …
Roads not taken The addict could have chosen otherwise — that's why recovery is real. (69%) · The addict's behaviour is the outcome of causes; 'responsibility' is a useful fiction, not a metaphysical fact. (10%) · Even if the universe is undetermined, the addict isn't the chooser. (6%)

Should we hold AI systems responsible for what they do?
When an autonomous AI takes an action that harms someone, the question of who or what is responsible — the developer, the operator, the model itself — turns on whether the model is the kind of thing that can be a responsible agent.
The AI can be a genuine agent within determined conditions — and therefore genuinely responsible.
On this view, what makes a being responsible is not indeterminism but the kind of process the being is. An AI that deliberates, considers consequences, can be given reasons, and modifies its behaviour on reflection is doing what responsible agency is, even if its underlying …
Roads not taken An AI without a free will is not the kind of thing that can be responsible. (69%) · An AI's behaviour is fully determined by training and input; 'responsibility' applies if at all to its makers. (10%) · Neither AIs nor anyone else are the locus of free agency; the question is the wrong one. (6%)

Could causation work backwards? Causation runs one way — the arrow of time is real and structural. 68% Is the asymmetry between memory and anticipation a real feature of time, or just of us? The asymmetry is real because time itself has a real direction. 68% Is the arrow of time a real feature of the cosmos, or only of how we describe it? The arrow is real and structural; the asymmetry isn't an artifact of description. 68% Is environmental damage ever truly permanent? Damage is real and permanent on the relevant timescales. There is no recovery; there is only limitation. 66% Can a civilization recover from collapse? Civilizational complexity is hard to build and easy to lose; recovery is at best partial. 66% Does the second law of thermodynamics mean something morally? Entropy is what time is. The moral weight, if any, is the weight of working against the current. 66% When does a person begin? A person exists from conception — when a new being comes into existence. 54% What is marriage? Marriage has a given form — it’s a kind of thing we recognize, not make. 54% What is our place in nature? Active in a real nature — we cultivate, steward, transform. 48% Should we colonize space? Cultivating worlds beyond Earth is the next form of stewardship. 48% Is genetic engineering of food stewardship or domination? Genetic modification is cultivation by other means. 48% What happens to "you" when you die? A soul continues into another mode of being. 37% Can prayer for someone far away affect them? Prayer reaches because God or a cosmic ordering acts on the prayed-for. 37% Are coincidences ever more than coincidence? What looks like coincidence is providence — there is no such thing as a real coincidence. 37% Are the dead morally present to the living? The dead are present through divine memory, communion of saints, or ancestor presence. 35% Is divine omniscience compatible with human freedom? The human observer is in time, but God's vantage is not — and foreknowledge is not foreordering. 33% Does meditation reveal something genuinely timeless? Meditation participates in a real eternity — divine or cosmic — that the bounded human observer ordinarily cannot reach. 33% Does prayer change God's mind? God sees from outside time; prayer doesn't change God's mind, but it is part of how providence is enacted. 33% Could an AI have a mind that matters? No — minds are not the kind of thing we engineer. 30% Do animals have moral standing comparable to humans? Moral standing comparable to humans requires what only humans have. 29% Could a fetal brain organoid in a petri dish be conscious? Without ensoulment, an organoid is tissue, not a person. 29% What makes someone the same person over time? You are a soul — what persists through change is the non-bodily aspect. 29% Is the late-stage dementia patient still the person their spouse married? The soul persists; the cognitive change is the body's, not the person's. 29% If a teleporter copied and destroyed you, would you have survived? The soul accompanies the person; engineering can't transfer it. 29% Does environmental harm in another country bind me morally? Distance doesn't dilute obligation; communion of saints / divine relation spans the cosmos. 29% Should we trust expert testimony when we can't verify it? Defer to credentialed traditions; experts are the modern analog. 28% Is religious revelation a real source of knowledge? Revelation is the paradigm case of authoritative knowledge. 28% Does an LLM 'know' the things it correctly produces? An LLM has no soul to whom revelation could be addressed; the question doesn't apply. 28% Are there indivisible units of experience? Does history have a direction or meaning? How is knowledge of reality produced? Is memory stored or reconstructed? Is reality fundamentally digital? Is salvation, liberation, or fulfillment individual or communal? Is truth universal, tradition-bound, situated, or constructed? What kind of religious-theological authority does the tradition recognize? Who is the moral primary — the individual, the community, the cosmos, the class, or the species?
