Chapter 4 — Part I: The Creed — Article II: And in Jesus Christ, His Only Son, Our Lord
Section 19. But when we are told that Jesus is the Son of God, we are not to understand anything earthly or mortal in His birth; but are firmly to believe and piously to adore that birth by which, from all eternity, the Father begot the Son, a mystery which reason cannot fully conceive or comprehend, and at the contemplation of which, overwhelmed, as it were, with admiration, we should exclaim with the Prophet: Who shall declare his generation? On this point, then, we are to believe that the Son is of the same nature, of the same power and wisdom, with the Father, as we more fully profess in these words of the Nicene Creed: And in one Lord Jesus Christ, his Only-begotten Son, born of the Father before all ages, God of God, light of light, true God of true God, begotten, not made, consubstantial to the Father, by whom all things were made.
