Prayer for the Unity of All Christendom

We pray to you, our Lord Jesus Christ, for the healing of Your Body, the Church. And that our Protestant and Orthodox brethren will be re-united with us in the Holy Catholic Church. We hope and pray for the fulfillment of Your own prayer: "I pray not only for them, but also for those who believe in me through their word, so that they may all be one, as you, Father, are in me and I in you, that they also may be in us, that the world may believe that you sent me. And I have given them the glory you gave me, so that they may be one, as we are one . . . ." (Jn 17, 20-22 NAB)
