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." Mt 16:16-17. 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..." Gal 1:15-16. "and in the synagogues immediately [Paul] proclaimed Jesus, saying, 'He is the Son of God.'" Acts 9:20. From the beginning this acknowledgment of Christ's divine sonship will be the centre of the apostolic faith, first professed by Peter as the Church's foundation. Cf. I Th 1:10; Jn 20:31; Mt 16:18.
