Basil rejected an allegorical interpretation in his Hexaëmeron, without commenting on the literalism of the days: Origen of Alexandria, in a passage that was later chosen by Gregory of Nazianzus for inclusion in the Philocalia, an anthology of some of his most important texts, made the following remarks: In Contra Celsum, an apologetic work written in response to the pagan intellectual Celsus, Origen also said: Saint Augustine, one of the most influential theologians of the Catholic Church, suggested that the Biblical text should not be interpreted literally if it contradicts what we know from science and our God-given reason. From an important passage on his The Literal Interpretation of Genesis (early fifth century, AD), St. Augustine wrote: In the book, Augustine took the view that everything in the universe was created simultaneously by God, and not in seven days like a plain account of Genesis would require. He argues that the six-day structure of creation presented in the book of Genesis represents a logical framework, rather than the passage of time in a physical way. Augustine also does not envisage original sin as originating structural changes in the universe, and even suggests that the bodies of Adam and Eve were already created mortal before the Fall. Apart from his specific views, Augustine recognizes that the interpretation of the creation story is difficult, and remarks that we should be willing to change our mind about it as new information comes up. In The City of God, Augustine rejected both the immortality of the human race proposed by pagans, and contemporary ideas of ages (such as those of certain Greeks and Egyptians) that differed from the Church's sacred writings: However, Augustine is quoting here about the age of human civilization not the age of the Earth based on his use of early Christian histories. Those histories are no longer considered accurate in terms of exact years and therefore either the 6000 years is not an exact number or the years aren't actual literal years. St. Augustine also comments on the word "day" in the creation week, admitting the interpretation is difficult: Contemporary Christian considerations Many modern Christian theologians, Roman Catholic, Eastern Orthodox, and mainline Protestants, have rejected literalistic interpretations of Genesis in favour of allegorical or mythopoietic interpretations such as the literary framework view. Many Christian Fundamentalists have considered such rejection unmerited. Sir Robert Anderson wrote, "Christ and Criticism" in The Fundamentals,
