CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 570–573

570 Jesus' entry into Jerusalem manifests the coming of the kingdom that the Messiah-King, welcomed into his city by children and the humble of heart, is going to accomplish by the Passover of his Death and Resurrection.
571 The Paschal mystery of Christ's cross and Resurrection stands at the center of the Good News that the apostles, and the Church following them, are to proclaim to the world. God's saving plan was accomplished "once for all" by the redemptive death of his Son Jesus Christ.
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.
