Compare Cat. iv. 4.  Irenæus (I. x. 1):  “The Church, though dispersed throughout the whole world, even to the ends of the earth, yet received from the Apostles and their disciples the Faith in One God the Father Almighty, Maker of heaven, and earth, and the sea and all that therein is.”  Tertullian (de Præscriptione Hæret. cap. xiii.)  “The rule of faith is that whereby we believe that there is One God only, and none other than the Creator of the world, who brought forth all things out of nothing through His own Word first of all sent forth.”
