I read an interesting book a while ago; Catholics, by Brian Moore. It is set in the (then) near future, where the Catholic Church has fully embraced the modern world (Vatican IV has recently been concluded), and the Church has been completely transformed. Liberation theology is taught in the theological colleges of Rome. The Protestant churches have been embraced, and Buddhist-Catholic ecumenicism is the new cause celebre. Confession, vestments, and Latin have been abolished. Transubstantiation is no longer a dogma. The main crux of the film seems to be that the authoritarian reactionary order of the Church, has been superseded by an authoritarian progressive one, but I digress.
The question is; what if the Catholic Church (let's set the POD from 1962) completes the "aggiornamento"? What would be the effects if, at the Second Vatican Council (or subsequent councils/Papal pronouncements), the Catholic Church opens to the world, allowing birth control, married priests, a much greater role for women in the Church, radical ecumenicism, and liberation theology, and ends the use of Latin, confession, literal interpretation of transubstantiation, and clerical wear? What are the effects, within the Church and out of it?
