2759 Jesus "was praying at a certain place, and when he ceased, one of his disciples said to him, 'Lord, teach us to pray, as John taught his disciples.'"1 In response to this request the Lord entrusts to his disciples and to his Church the fundamental Christian prayer. St. Luke presents a brief text of five petitions,2 while St. Matthew gives a more developed version of seven petitions.3 The liturgical tradition of the Church has retained St. Matthew's text:
2760 Very early on, liturgical usage concluded the Lord's Prayer with a doxology. In the Didache, we find, "For yours are the power and the glory for ever."4 The Apostolic Constitutions add to the beginning: "the kingdom," and this is the formula retained to our day in ecumenical prayer.5 The Byzantine tradition adds after "the glory" the words "Father, Son, and Holy Spirit." The Roman Missal develops the last petition in the explicit perspective of "awaiting our blessed hope" and of the Second Coming of our Lord Jesus Christ.6 Then comes the assembly's acclamation or the repetition of the doxology from the Apostolic Constitutions.
1 Lk 11:1.
