Origens Commentary On The Gospel Of John by Origen
32. Christ as Son.
None of these testimonies, however, sets forth distinctly the Saviour's exalted birth; but when the words are addressed to Him, |Thou art My Son, this day have I begotten Thee,| this is spoken to Him by God, with whom all time is to-day, for there is no evening with God, as I consider, and there is no morning, nothing but time that stretches out, along with His unbeginning and unseen life. The day is to-day with Him in which the Son was begotten, and thus the beginning of His birth is not found, as neither is the day of it.
