CIC 708 This divine pedagogy appears especially in the gift of the Law.1 God gave the Law as a “pedagogue” to lead his people toward Christ.2 But the Law’s powerlessness to save man deprived of the divine “likeness,” along with the growing awareness of sin that it imparts,3 enkindles a desire for the Holy Spirit. The lamentations of the Psalms bear witness to this.
CIC 1334 In the Old Covenant bread and wine were offered in sacrifice among the first fruits of the earth as a sign of grateful acknowledgment to the Creator. But they also received a new significance in the context of the Exodus: the unleavened bread that Israel eats every year at Passover commemorates the haste of the departure that liberated them from Egypt; the remembrance of the manna in the desert will always recall to Israel that it lives by the bread of the Word of God;4 their daily bread is the fruit of the promised land, the pledge of God’s faithfulness to his promises. The “cup of blessing”5 at the end of the Jewish Passover meal adds to the festive joy of wine an eschatological dimension: the messianic expectation of the rebuilding of Jerusalem. When Jesus instituted the Eucharist, he gave a new and definitive meaning to the blessing of the bread and the cup.
CIC 2835 This petition, with the responsibility it involves, also applies to another hunger from which men are perishing: “Man does not live by bread alone, but. .. by every word that proceeds from the mouth of God,”6 that is, by the Word he speaks and the Spirit he breathes forth. Christians must make every effort “to proclaim the good news to the poor.” There is a famine on earth, “not a famine of bread, nor a thirst for water, but of hearing the words of the LORD.”7 For this reason the specifically Christian sense of this fourth petition concerns the Bread of Life: The Word of God accepted in faith, the Body of Christ received in the Eucharist.8
