From January 18 through January 25, Christians throughout the world will be keeping the Week of Prayer for Christian Unity. The Octave, as originally conceived by Father Paul of Graymoor, reflects the unchanging truth that there can be no real unity apart from union upon that Rock, established by Christ Himself, which is Peter and his successors. For that reason, St. Peter is considered the special Patron of the Octave of Prayer for Christian Unity.

THE OCTAVE PRAYERS

ANTIPHON: That they all may be one, as Thou, Father, in me and I in Thee; that they also may be one in Us; that the world may believe that Thou hast sent me.
V. I say unto thee, thou art Peter;

R. And upon this rock I will build my Church.

[Here is brought to mind the intention for the day's prayer.]

January 18: For the return of the “other sheep” to the One Fold of our Lord Jesus Christ.

January 19: For the return of the Eastern Orthodox Christians to communion with the Apostolic See.

January 20: For the return of the Anglicans to the authority of the Vicar of Christ.

January 21: For the return of all Protestants throughout the world to the unity of the Catholic Church.

January 22: That Christians in America (or, in my own country) may be one, in union with the Chair of Saint Peter.

January 23: That lapsed Catholics will return to the Sacraments of the Church.

January 24: That the Jewish people will be converted to the Catholic Faith.

January 25: That missionary zeal will conquer the world for Christ.
Let us pray. O Lord Jesus Christ, who saidst to thine Apostles, Peace I leave with you; my peace I give unto you: regard not our sins, but the faith of thy Church; and grant to her peace and unity according to thy will; who livest and reignest with the Father and the Holy Spirit, ever one God, world without end. Amen.
