CCC 442 Such is not the case for Simon Peter when he confesses Jesus as “the Christ, the Son of the living God”, for Jesus responds solemnly: “Flesh and blood has not revealed this to you, but my Father who is in heaven.”1 Similarly Paul will write, regarding his conversion on the road to Damascus, “When he who had set me apart before I was born, and had called me through his grace, was pleased to reveal his Son to me, in order that I might preach him among the Gentiles. ..”2 “And in the synagogues immediately [Paul] proclaimed Jesus, saying, ‘He is the Son of God.’”3 From the beginning this acknowledgment of Christ’s divine sonship will be the center of the apostolic faith, first professed by Peter as the Church’s foundation.4
