For anyone who can get a copy of it, I warmly recommend the tract Reunion All Round by Msgr Ronald Knox for a satirical look at how the world's religions may come together under the Church of England. The following extract concerns admission of Roman Catholics to the new church:

"I would not, I mean, altogether treat their Orders as null and void, but only degrade their clergy by single step in the Hierarchy; their Bishops to count as Priests, their Priests as Deacons, their Deacons as Layreaders. Nor would I extract from these, by way of a Declaration of Loyalty to our Church, anything more than an Affirmation of general Dissent from the Doctrine contained in the Thirty-Nine Articles of Religion. The Pope himself I would allow to take rank as a retired Missionary Bishop, thus leaving him the Insignia of Power without any Sphere in which to exercise, or Income with which to abuse it. The Cardinals I would disperse among the Common-rooms of Oxford and Cambridge, where they could exercise to the full their Talent for Intrigue without having any serious effect, for good or ill, upon the Destinies of the Nations.
