Against the eternal cosmos of the Greeks, the Church Fathers fixed the doctrine of creatio ex nihilo: God freely makes the world out of nothing, with no pre-existent matter and no necessity, so that the world has a beginning and stands wholly other than its Creator. But the same tradition carried a Neoplatonic current, most fully in Eriugena's Periphyseon, where all things proceed from God and return to Him in a great procession that reads creation as theophany. Aquinas later separated two questions the dispute had fused. The map holds the readings.
Creatio ex nihilo, a free making of the world out of nothing by a willing God, became the settled Christian doctrine, defined against both Greek eternalism and any co-eternal matter. But a Neoplatonic emanationist current ran through the tradition, fullest in Eriugena and later in Eckhart, reading creation as the procession of all things from God. Aquinas separated the metaphysical claim of creation from the indemonstrable question of a temporal beginning. No reading is adjudicated here.
God freely makes the world out of nothing -- a beginning, and a real Creator/creation gap
God created the world out of nothing (ex nihilo), freely and by His will, with no pre-existent matter to shape and under no necessity. Against the Greek picture of an eternal cosmos and against any co-eternal matter, the doctrine secures three things at once: that the world had a beginning, that it depends utterly on God, and that it is genuinely other than God, neither a part of Him nor an emanation of His substance. Creation is a free act of a willing Creator, not an overflow.
lens The patristic consensus (Theophilus, Irenaeus, Augustine), defined against Greek eternalism and Gnostic-Platonic pre-existent matter.
The patristic creatio-ex-nihilo doctrine and its definition against eternalism and pre-existent matter are treated in Davidson 1987's account of the doctrine's background and Christian penetration. (SUGYA-ENGINE.md §11)
all proceeds from God and returns to Him -- creation as theophany, a procession
In the Periphyseon, all things proceed from God and return to Him. God is 'that which creates and is not created'; from Him flow the primordial causes ('that which is created and creates') and then the world of creatures ('that which is created and does not create'), which at the end returns into 'that which neither creates nor is created.' Creation is read as theophany, the self-manifestation of the hidden God, a Neoplatonic procession-and-return rather than a single making out of nothing at an instant. The gap of pure nothing is softened into a moment in the divine self-unfolding.
Eriugena's four divisions and the procession-and-return are verbatim structural features of the Periphyseon (public-domain). (§11)
creation (dependence) is certain; a temporal beginning is held by faith, not demonstrable
Two questions must be separated. That the world is created, that it depends absolutely on God for its being, is metaphysically certain and is what creatio ex nihilo means. But whether the world had a temporal beginning cannot be demonstrated by reason: a created world could, for all philosophy can show, have been created from eternity. The beginning is held by faith, on the authority of Genesis, not proved. Against the Aristotelians who think eternity demonstrable and the theologians who think a beginning demonstrable, Aquinas grants neither.
Aquinas's distinction between creation-as-dependence and the indemonstrability of a temporal beginning is documented in Davidson 1987's account of the dispute's reception. (§11)
Did God make the world out of nothing, freely and at a beginning, leaving it wholly other than Himself (the Fathers), or does all proceed from God and return to Him in a procession that reads creation as theophany (Eriugena)? The Christian form of the same fault-line, with the Neoplatonic inheritance pulling toward emanation against the patristic ex nihilo.
Staged in: John Scotus Eriugena; Davidson, Herbert A. (1987)
If, with Aquinas, a created world might have been created from eternity, how much distance is really left between creatio ex nihilo and the emanation it was framed to deny?
