Roman Catechism 6.8

Chapter 6 — Part I: The Creed — Article IV: Suffered Under Pontius Pilate, Was Crucified, Dead, and Buried

Section 8. Importance Of The History Of The Passion — Furthermore, the pastor should not omit the historical part of this Article, which has been so carefully set forth by the holy Evangelists; so that the faithful may be acquainted with at least the principal points of this mystery, that is to say, such as seem more necessary to confirm the truth of our faith. For it is on this Article, as on their foundation, that the Christian faith and religion rest; and if this truth be firmly established, all the rest is secure. Indeed, if one thing more than another presents difficulty to the mind and understanding of man, assuredly it is the mystery of the cross, which, beyond all doubt, must be considered the most difficult of all; so much so that only with great difficulty can we grasp the fact that our salvation depends on the cross, and on Him who for us was nailed thereon. In this, however, as the Apostle teaches, we may well admire the wonderful Providence of God; for, seeing that in the wisdom of God, the world by wisdom knew not God, it pleased God by the foolishness of preaching, to save them that believe. It is no wonder, then, that the Prophets, before the coming of Christ, and the Apostles, after His death and Resurrection, labored so strenuously to convince mankind that He was the Redeemer of the world, and to bring them under the power and obedience of the Crucified.
