Catechism of the Catholic Church :
571 The Paschal mystery of the Cross and Resurrection of Christ is central to the Good News that the apostles and the Church after them, must announce the world. The God's saving plan was accomplished "once for all" (Heb 9, 26) by the redemptive death of His Son Jesus Christ.
572 The Church remains faithful to "the interpretation of the scriptures" given by Jesus himself before and after his Passover: "Ought not the Messiah should suffer these things enter into his glory? "(Lk 24, 26-27. 44-45). The sufferings of Jesus took their historical, concrete form that it was" rejected by the elders, chief priests and scribes "(Mk 8, 31) who "delivered to the Gentiles to be mocked and scourged and crucified" (Mt 20, 19).
573 Faith can try to scrutinize the circumstances of Jesus' death, faithfully handed on by the Gospels (cf. . DV 19) and illuminated by other historical sources, to better understand the meaning of redemption.
