On account of this difference of term He is said by the divine Paul to be “without father, without mother, without descent, having neither beginning of days nor end of life.” He is without father as touching His humanity; for as man He was born of a mother alone. And He is without mother as God, for He was begotten from everlasting of the Father alone. And again He is without descent as God while as man He has descent. For it is written “The book of the generation of Jesus Christ the son of David, the son of Abraham.” His descent is also given by the divine Luke. So again, as God, He has no beginning of days for He was begotten before the ages; neither has He an end of life, for His nature is immortal and impassible. But as man He had both a beginning of days, for He was born in the reign of Augustus Cæsar, and an end of life, for He was crucified in the reign of Tiberius Cæsar. But now, as I have already said, even His human nature is immortal; and, as He ascended, so again shall He come according to the words of the Angel—“This same Jesus which is taken up from you into Heaven shall so come in like manner as ye have seen Him go into Heaven.”
