CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 2837–2841

2837 "Daily" (epiousios) occurs nowhere else in the New Testament. Taken in a temporal sense, this word is a pedagogical repetition of "this day," 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. 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. 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.

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.

2838 This petition is astonishing. If it consisted only of the first phrase, "And forgive us our trespasses," it might have been included, implicitly, in the first three petitions of the Lord's Prayer, since Christ's sacrifice is "that sins may be forgiven." But, according to the second phrase, our petition will not be heard unless we have first met a strict requirement. Our petition looks to the future, but our response must come first, for the two parts are joined by the single word "as."
2839 With bold confidence, we began praying to our Father. In begging him that his name be hallowed, we were in fact asking him that we ourselves might be always made more holy. But though we are clothed with the baptismal garment, we do not cease to sin, to turn away from God. Now, in this new petition, we return to him like the prodigal son and, like the tax collector, recognize that we are sinners before him. Our petition begins with a "confession" of our wretchedness and his mercy. Our hope is firm because, in his Son, "we have redemption, the forgiveness of sins." We find the efficacious and undoubted sign of his forgiveness in the sacraments of his Church.
2840 Now - and this is daunting - this outpouring of mercy cannot penetrate our hearts as long as we have not forgiven those who have trespassed against us. Love, like the Body of Christ, is indivisible; we cannot love the God we cannot see if we do not love the brother or sister we do see. In refusing to forgive our brothers and sisters, our hearts are closed and their hardness makes them impervious to the Father's merciful love; but in confessing our sins, our hearts are opened to his grace.
2841 This petition is so important that it is the only one to which the Lord returns and which he develops explicitly in the Sermon on the Mount. This crucial requirement of the covenant mystery is impossible for man. But "with God all things are possible."
