The Athanasian Creed (late 400s)

Soon after the writing of the Chalcedon Creed in 451, someone in the western Latin church, probably from southern France, wrote a summarized creed that is today known as the Athanasian Creed. This was not written by Athanasius of Alexandria, Egypt. It states:

“It is necessary to everlasting salvation that he also believe rightly the incarnation of our Lord Jesus Christ. For the right (orthodox) faith is that we believe and confess that our Lord Jesus Christ, the Son of God, is God and human. God of the substance of the Father, begotten before the worlds; and man of substance of his mother, born in the world. Perfect God and perfect man, of a reasonable (rational) soul and human flesh subsisting. Equal to the Father as touching his Godhead, and inferior to the Father as touching his humanity. Who, although he is God and human, yet he is not two, but one Christ. One, not by conversion of the Godhead into flesh, but by taking of humanity into God. One altogether, not by confusion of substance, but by unity of person. For as the reasonable (rational) soul and flesh is one man, so God and man is one Christ. This is the universal (catholic) faith, which, except a man believe faithfully, he cannot be saved.”
