Jan. 18-25: Week of Prayer for Christian Unity

That they may all be one; even as thou, Father, art in me, and I in thee,
that they also may be in us, so that the world may believe that thou hast sent me.
[Jn 17, 21]

History of the Week of Prayer for Christian Unity

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 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.

[The following prayer is then said.]

Let us pray. O Lord Jesus Christ, who saidst unto Thine Apostles: Peace I leave you, My peace I give to you; regard not our sins, but the faith of Thy Church, and grant unto her that peace and unity which are agreeable to Thy Will; Who livest and reignest ever, one God, world without end. Amen.
