CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 2790–2793

2790 Grammatically, "our" qualifies a reality common to more than one person. There is only one God, and he is recognized as Father by those who, through faith in his only Son, are reborn of him by water and the Spirit. The Church is this new communion of God and men. United with the only Son, who has become "the firstborn among many brethren," she is in communion with one and the same Father in one and the same Holy Spirit. In praying "our" Father, each of the baptized is praying in this communion: "The company of those who believed were of one heart and soul."
2791 For this reason, in spite of the divisions among Christians, this prayer to "our" Father remains our common patrimony and an urgent summons for all the baptized. In communion by faith in Christ and by Baptism, they ought to join in Jesus' prayer for the unity of his disciples.
2792 Finally, if we pray the Our Father sincerely, we leave individualism behind, because the love that we receive frees us from it. The "our" at the beginning of the Lord's Prayer, like the "us" of the last four petitions, excludes no one. If we are to say it truthfully, our divisions and oppositions have to be overcome.
2793 The baptized cannot pray to "our" Father without bringing before him all those for whom he gave his beloved Son. God's love has no bounds, neither should our prayer. Praying "our" Father opens to us the dimensions of his love revealed in Christ: praying with and for all who do not yet know him, so that Christ may "gather into one the children of God." God's care for all men and for the whole of creation has inspired all the great practitioners of prayer; it should extend our prayer to the full breadth of love whenever we dare to say "our" Father.
