§1094

It is on this harmony of the two Testaments that the Paschal catechesis of the Lord is built, and then, that of the Apostles and the Fathers of the Church. This catechesis unveils what lay hidden under the letter of the Old Testament: the mystery of Christ. It is called "typological" because it reveals the newness of Christ on the basis of the "figures" (types) which announce him in the deeds, words, and symbols of the first covenant. By this re-reading in the Spirit of Truth, starting from Christ, the figures are unveiled. Thus the flood and Noah's ark prefigured salvation by Baptism, as did the cloud and the crossing of the Red Sea. Water from the rock was the figure of the spiritual gifts of Christ, and manna in the desert prefigured the Eucharist, "the true bread from heaven."
