And yet, who will deny that whatever is not the one faith, is not faith at all? For in the one faith there is one Lord Christ, and God the Father is one. But the one Lord Jesus Christ is not one in the truth of the confession, as well as in name, unless He is Son, unless He is God Reading ‘unus est, si filius sit, si Deus sit.’, unless He is unchangeable, unless His Sonship and His Godhead have been eternally present in Him. He who preaches Christ other than He is, that is, other than Son and God, preaches another Christ. Nor is he in the one faith of the one baptism, for in the teaching of the Apostle the one faith is the faith of that one baptism, in which the one Lord is Christ, the Son of God Who is also God.
