2855 The final doxology, "For the kingdom, the power and the glory are yours, now and forever," takes up again, by inclusion, the first three petitions to our Father: the glorification of his name, the coming of his reign, and the power of his saving will. But these prayers are now proclaimed as adoration and thanksgiving, as in the liturgy of heaven.176 The ruler of this world has mendaciously attributed to himself the three titles of kingship, power, and glory.177 Christ, the Lord, restores them to his Father and our Father, until he hands over the kingdom to him when the mystery of salvation will be brought to its completion and God will be all in all.178
2856 "Then, after the prayer is over you say 'Amen,' which means 'So be it,' thus ratifying with our 'Amen' what is contained in the prayer that God has taught us."179
2857 In the Our Father, the object of the first three petitions is the glory of the Father: the sanctification of his name, the coming of the kingdom, and the fulfillment of his will. The four others present our wants to him: they ask that our lives be nourished, healed of sin, and made victorious in the struggle of good over evil.
2861 In the fourth petition, by saying "give us," we express in communion with our brethren our filial trust in our heavenly Father. "Our daily bread" refers to the earthly nourishment necessary to everyone for subsistence, and also to the Bread of Life: the Word of God and the Body of Christ. It is received in God's "today," as the indispensable, (super-) essential nourishment of the feast of the coming Kingdom anticipated in the Eucharist.
2863 When we say "lead us not into temptation" we are asking God not to allow us to take the path that leads to sin. This petition implores the Spirit of discernment and strength; it requests the grace of vigilance and final perseverance.
2864 In the last petition, "but deliver us from evil," Christians pray to God with the Church to show forth the victory, already won by Christ, over the "ruler of this world," Satan, the angel personally opposed to God and to his plan of salvation.
