The patristic consensus on Genesis creation is more nuanced — and more surprising — than the modern debate often assumes. Augustine, by far the most systematic patristic interpreter of Genesis, rejected a literal sequential reading of the seven days in favor of an instantaneous creation followed by an ordered narrative presentation. His key move, developed across the Confessions and his commentaries on Genesis, was to distinguish the act of creation (atemporal, from nothing, ex nihilo) from the textual enumeration of days (pedagogical, arranged for audiences who needed progressive structure). The days in Genesis are not a diary of divine activity but a literary ordering of what God created simultaneously in wisdom. God, who exists beyond time, does not work in sequence as though wearied — the text's structure serves the reader, not God's labor. Basil of Caesarea, in his Hexaemeron homilies, engaged the physical description of the creation week more directly than Augustine, but with a consistent anti-dualist agenda. The invisible earth was not metaphysically evil or chaotic — it was physically covered by deep water in darkness, a natural condition prior to God's ordering act. Basil's realism about the text's physical language did not entail a naive literalism; rather, it defended creation's original goodness against Gnostic and Manichaean readings that treated formless matter as hostile or uncreated. Tatian, writing in the mid-second century, made the contrast with pagan cosmologies explicit: while Greek philosophers contradicted each other endlessly over whether the world was uncreated, self-generating, or providentially made, Christians held to a single unified Creator whose act was complete, purposeful, and non-competitive with any rival principle. The patristic witness as a whole resists both a naive seven-day literalism and any process cosmology: creation is God's single, eternal act of ordering, beyond time, from nothing.
"In the Beginning God created Heaven and Earth: and the Earth was invisible and without form, and darkness was upon the deep, and not mentioning what day Thou createdst them...it is, then, on account of these two, a primitive formed, and a primitive formless; the one, heaven but the Heaven of heaven, the other earth but the earth invisible and without form; because of these two do I conceive, did Thy Scripture say without mention of days, In the Beginning God created Heaven and Earth." Augustine's reading of Genesis 1:1–2 as describing atemporal, formless origins — before days begin — is his foundational argument against a literal sequential creation week. Creation and time are not co-eternal; God's act precedes and originates both. (NPNF1-01)
"O man, why wander thus from the truth...'The earth was invisible.' Why? Because the 'deep' was spread over its surface...The rays of the sun, penetrating the water, often allow us to see the pebbles which form the bed of the river, but in a dark night it is impossible for our glance to penetrate under the water." Basil explains the invisible earth naturalistically — physical obscuration by water and darkness, not metaphysical evil or chaos — rejecting dualistic readings that would turn Genesis's formless matter into a rival hostile power. Creation's initial state is not evil; it is simply unformed matter under God's sovereign hand. (NPNF2-08)
