Therefore "there is one God," the Father, "and without Him there is none else." And when He Himself makes this declaration, He denies not the Son, but says that there is no other God; and the Son is not different from the Father.
Igitur unus deus pater, et absque eo alius non est: quod ipse inferens non filium negat sed alium deum: ceterum alius a patre filius non est.
