Jesus Prayed It ... So Can We

In 1935, Abbé Paul Couturier, a priest of the Archdiocese of Lyons, sought a solution to the problem of non-Roman Catholics not being able to observe the Octave of Prayer for Christian Unity. He found the solution in the Roman Missal as the Association for Promotion of the Unity of Christians had done seventy-eight years earlier in England. Couturier promoted prayer for Christian unity on the inclusive basis that “our Lord would grant to his Church on earth that peace and unity which were in his mind and purpose, when, on the eve of His Passion, He prayed that all might be one.” This prayer would unite Christians in prayer for that perfect unity that God wills and by the means that he wills. Like Fr. Paul Wattson, Abbé Couturier exhibited a powerful passion for unity and had sent out “calls to prayer” annually until his death in 1953.
