Chapter 40 — How generation in God is understood

Hence in the rule of Catholic faith we are taught to profess belief in the Father and Son in God by saying: I believe in God the Father, and in his Son. And lest anyone, hearing Father and Son mentioned, should have any notion of carnal generation, according to which father and son receive their designation among us, John the Evangelist, to whom were revealed heavenly mysteries, substitutes Word for Son (John 1:14), so that we may understand that the generation is intellectual.
