59. Since it was taught that the Son did not, like all other things, owe His existence to God's will, lest He should be thought to derive His essence only at His Father's will and not in virtue of His own nature, an opportunity seemed thereby to be given to heretics to attribute to God the Father a necessity of begetting the Son from Himself, as though He had brought forth the Son by a law of nature in spite of Himself. But such liability to be acted upon does not exist in God the Father in the ineffable and perfect birth of the Son it was neither mere will that begat Him nor was the Father's essence changed or forced at the bidding of a natural law. Nor was any substance sought for to beget Him, nor is the nature of the Begetter changed in the Begotten, nor is the Father's unique name affected by time. Before all time the Father, out of the essence of His nature, with a desire that was subject to no passion, gave to the Son a birth that conveyed the essence of His nature.

XXVI. "If any man says that the Son is incapable of birth and without beginning, speaking as though there were two incapable of birth and unborn and without beginning, and makes two Gods: let him be anathema. For the Head, which is the beginning of all things, is the Son; but the Head or beginning of Christ is God: for so to One who is without beginning and is the beginning of all things, we refer the whole world through Christ."
