CCC 151 For a Christian, believing in God cannot be separated from believing in the One he sent, his “beloved Son”, in whom the Father is “well pleased”; God tells us to listen to him.1 The Lord himself said to his disciples: “Believe in God, believe also in me.”2 We can believe in Jesus Christ because he is himself God, the Word made flesh: “No one has ever seen God; the only Son, who is in the bosom of the Father, he has made him known.”3 Because he “has seen the Father”, Jesus Christ is the only one who knows him and can reveal him.4

CCC 459 The Word became flesh to be our model of holiness: “Take my yoke upon you, and learn from me.” “I am the way, and the truth, and the life; no one comes to the Father, but by me.”5 On the mountain of the Transfiguration, the Father commands: “Listen to him!”6 Jesus is the model for the Beatitudes and the norm of the new law: “Love one another as I have loved you.”7 This love implies an effective offering of oneself, after his example.8

CCC 516 Christ’s whole earthly life – his words and deeds, his silences and sufferings, indeed his manner of being and speaking – is Revelation of the Father. Jesus can say: “Whoever has seen me has seen the Father”, and the Father can say: “This is my Son, my Chosen; listen to him!”9 Because our Lord became man in order to do his Father’s will, even the least characteristics of his mysteries manifest “God’s love. .. among us”.10

CCC 552 Simon Peter holds the first place in the college of the Twelve;11 Jesus entrusted a unique mission to him. Through a revelation from the Father, Peter had confessed: “You are the Christ, the Son of the living God.” Our Lord then declared to him: “You are Peter, and on this rock I will build my Church, and the gates of Hades will not prevail against it.”12 Christ, the “living Stone”,13 thus assures his Church, built on Peter, of victory over the powers of death. Because of the faith he confessed Peter will remain the unshakable rock of the Church. His mission will be to keep this faith from every lapse and to strengthen his brothers in it.14

CCC 649 As for the Son, he effects his own Resurrection by virtue of his divine power. Jesus announces that the Son of man will have to suffer much, die, and then rise.15 Elsewhere he affirms explicitly: “I lay down my life, that I may take it again. .. I have power to lay it down, and I have power to take it again.”16 “We believe that Jesus died and rose again.”17
