"For who that has understanding will suppose that the first and second and third day existed without a sun and moon and stars and that the first day was, as it were, also without a sky? . . . I do not suppose that anyone doubts that these things figuratively indicate certain mysteries, the history having taken place in appearance and not literally" (The Fundamental Doctrines 4:1:16 [A.D. 225]). -- Origen
"And how could creation take place in time, seeing time was born along with things which exist? . . . That, then, we may be taught that the world was originated and not suppose that God made it in time, prophecy adds: ‘This is the book of the generation, also of the things in them, when they were created in the day that God made heaven and earth’ [Gen. 2:4]. For the expression ‘when they were created’ intimates an indefinite and dateless production. But the expression ‘in the day that God made them,’ that is, in and by which God made ‘all things,’ and ‘without which not even one thing was made,’ points out the activity exerted by the Son" (Miscellanies 6:16 [A.D. 208]). -- Clement of Alexandria
"For as Adam was told that in the day he ate of the tree he would die, we know that he did not complete a thousand years [Gen. 5:5]. We have perceived, moreover, that the expression ‘The day of the Lord is a thousand years’ [Ps. 90:4] is connected with this subject" (Dialogue with Trypho the Jew 81 [A.D. 155]). -- Justin Martyr
