The Society of the Atonement at Graymoor began its life as a religious order of the Episcopal Church but was received into the Roman Catholic Church in 1909. One of its major emphases is unity, and thus they began the Week of Prayer for Christian Unity, which is widely observed in the Episcopal Church, Protestant denominations, and the Roman Catholic Church.
The unity of Christ’s Body the Church ought always to be a concern of prayer among Franciscans.
Collect: Holy God, who calls us in the Body of your Son Jesus Christ to continue his work of reconciliation and reveal you to all the world: Forgive us the sins which tear us apart. Give us the courage to overcome our fears and to seek that unity which is your gift and your will; through Jesus Christ our Lord. Amen.
