Catechism of the Catholic Church
2828 "Give us": The trust of children who look to their Father for everything is beautiful. "He makes his sun rise on the evil and on the good, and sends rain on the just and on the unjust." 113 He gives to all the living "their food in due season." 114 Jesus teaches us this petition, because it glorifies our Father by acknowledging how good he is, beyond all goodness.
2829 "Give us" also expresses the covenant. We are his and he is ours, for our sake. But this "us" also recognizes him as the Father of all men and we pray to him for them all, in solidarity with their needs and sufferings.
2830 "Our bread": The Father who gives us life cannot not but give us the nourishment life requires - all appropriate goods and blessings, both material and spiritual. In the Sermon on the Mount, Jesus insists on the filial trust that cooperates with our Father's providence. 115 He is not inviting us to idleness, 116 but wants to relieve us from nagging worry and preoccupation. Such is the filial surrender of the children of God:
To those who seek the kingdom of God and his righteousness, he has promised to give all else besides. Since everything indeed belongs to God, he who possesses God wants for nothing, if he himself is not found wanting before God. 117
2831 But the presence of those who hunger because they lack bread opens up another profound meaning of this petition. The drama of hunger in the world calls Christians who pray sincerely to exercise responsibility toward their brethren, both in their personal behavior and in their solidarity with the human family. This petition of the Lord's Prayer cannot be isolated from the parables of the poor man Lazarus and of the Last Judgment. 118
2832 As leaven in the dough, the newness of the kingdom should make the earth "rise" by the Spirit of Christ. 119 This must be shown by the establishment of justice in personal and social, economic and international relations, without ever forgetting that there are no just structures without people who want to be just.
2833 "Our" bread is the "one" loaf for the "many." In the Beatitudes "poverty" is the virtue of sharing: it calls us to communicate and share both material and spiritual goods, not by coercion but out of love, so that the abundance of some may remedy the needs of others. 120
2834 "Pray and work." 121 "Pray as if everything depended on God and work as if everything depended on you." 122 Even when we have done our work, the food we receive is still a gift from our Father; it is good to ask him for it and to thank him, as Christian families do when saying grace at meals.
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," 123 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." 124 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. 125
2836 "This day" is also an expression of trust taught us by the Lord, 126 which we would never have presumed to invent. Since it refers above all to his Word and to the Body of his Son, this "today" is not only that of our mortal time, but also the "today" of God.
If you receive the bread each day, each day is today for you. If Christ is yours today, he rises for you every day. How can this be? "You are my Son, today I have begotten you." Therefore, "today" is when Christ rises. 127
2837 "Daily" (epiousios) occurs nowhere else in the New Testament. Taken in a temporal sense, this word is a pedagogical repetition of "this day," 128 to confirm us in trust "without reservation." Taken in the qualitative sense, it signifies what is necessary for life, and more broadly every good thing sufficient for subsistence. 129 Taken literally (epi-ousios: "super-essential"), it refers directly to the Bread of Life, the Body of Christ, the "medicine of immortality," without which we have no life within us. 130 Finally in this connection, its heavenly meaning is evident: "this day" is the Day of the Lord, the day of the feast of the kingdom, anticipated in the Eucharist that is already the foretaste of the kingdom to come. For this reason it is fitting for the Eucharistic liturgy to be celebrated each day.
The Eucharist is our daily bread. The power belonging to this divine food makes it a bond of union. Its effect is then understood as unity, so that, gathered into his Body and made members of him, we may become what we receive.... This also is our daily bread: the readings you hear each day in church and the hymns you hear and sing. All these are necessities for our pilgrimage. 131
The Father in heaven urges us, as children of heaven, to ask for the bread of heaven. [Christ] himself is the bread who, sown in the Virgin, raised up in the flesh, kneaded in the Passion, baked in the oven of the tomb, reserved in churches, brought to altars, furnishes the faithful each day with food from heaven. 132
