"In the Holy Catholic Church, although the Eastern branch still stands aside, although the Roman Communion has added to the Faith, although the Anglican body often speaks with hesitating voice, and all are hampered by party differences, they are nevertheless one in Christ. These three Communions, the Anglican, the Eastern and the Roman, all trace their descent through the Undivided Church, to the Apostles. When in God’s Providence reunion or intercommunion comes, it will have to be brought about by the drawing together of these three branches of the Ancient Church, numbering four hundred million souls, who agree in the essentials of Doctrine, Discipline and Worship."
