Catechism of the Catholic Church

The Lord's Prayer is the quintessential prayer of the Church. It is an integral part of the major hours of the Divine Office and of the sacraments of Christian initiation: Baptism, Confirmation, and Eucharist. Integrated into the Eucharist it reveals the eschatological character of its petitions, hoping for the Lord, "until he comes" (1 Cor 11:26).
