De Synodis 2726
Open in the readerXXVI. "If any man says that the Son is incapable of birth and without beginning, saying 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.
