+ Mk 8: 27-33
Now Jesus and his disciples set out for the villages of Caesarea Philippi. Along the way he asked his disciples, “Who do people say that I am?”
They said in reply, “John the Baptist, others Elijah, still others one of the prophets.”
And he asked them, “But who do you say that I am?” Peter said to him in reply, “You are the Messiah.”
Then he warned them not to tell anyone about him.
He began to teach them that the Son of Man must suffer greatly and be rejected by the elders, the chief priests, and the scribes, and be killed, and rise after three days.
He spoke this openly. Then Peter took him aside and began to rebuke him.
At this he turned around and, looking at his disciples, rebuked Peter and said, “Get behind me, Satan. You are thinking not as God does, but as human beings do.”

The Catechism of the Catholic Church
472 This human soul that the Son of God assumed is endowed with a true human knowledge. As such, this knowledge could not in itself be unlimited: it was exercised in the historical conditions of his existence in space and time. This is why the Son of God could, when he became man, “increase in wisdom and in stature, and in favor with God and man”, and would even have to inquire for himself about what one in the human condition can learn only from experience. This corresponded to the reality of his voluntary emptying of himself, taking “the form of a slave”.
474 By its union to the divine wisdom in the person of the Word incarnate, Christ enjoyed in his human knowledge the fullness of understanding of the eternal plans he had come to reveal. What he admitted to not knowing in this area, he elsewhere declared himself not sent to reveal.
557 “When the days drew near for him to be taken up Jesus set his face to go to Jerusalem.” By this decision he indicated that he was going up to Jerusalem prepared to die there. Three times he had announced his Passion and Resurrection; now, heading toward Jerusalem, Jesus says: “It cannot be that a prophet should perish away from Jerusalem.”
572 The Church remains faithful to the interpretation of “all the Scriptures” that Jesus gave both before and after his Passover: “Was it not necessary that the Christ should suffer these things and enter into his glory?” Jesus’ sufferings took their historical, concrete form from the fact that he was “rejected by the elders and the chief priests and the scribes”, who handed “him to the Gentiles to be mocked and scourged and crucified”.
573 Faith can therefore try to examine the circumstances of Jesus’ death, faithfully handed on by the Gospels and illuminated by other historical sources, the better to understand the meaning of the Redemption.
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. 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.” “We believe that Jesus died and rose again.”
