You assume TEC (as they now abbreviate their name) is still a Christian demonination. Much of the reason for the decline in numbers is that Christians have fled TEC to “swim the Bosphorus”, “swim the Tiber”, put themselves under Anglican bishops from Africa, where Anglicanism still exists in its classical, identifiably Christian form, or set up “continuing Anglican churches”. What’s left, the nice old church ladies whose first loyalty is to their parish aside, is at best as Christian as the libertine strains of gnosticism from the first few Christian centuries.
The moment “Anglican inclusiveness” started including not just low-church evangelicals, broadchurchmen and Anglo-Catholics, but folks who deny tenants of what Lewis called “mere Christianity” (like the Holy Trinity, cf. Bishop Pike) the game was up even before the slide into embracing secular “morality”.
The Vatican HAS written their "ordinarium" which allows them to keep their own litury, which is also what they wanted when they would become Catholics.
The Vatican said "yes" and with some alterations, that is, the Transubstantiation, and all those TEC and Anglicans will be Catholic.
There were so many Anglican and TEC priests (all men, of course) who wanted to become Catholic priests (keeping wife, of course) that a seminary was opened in this country. A second seminary has opened recently.
I agree 100% with YOUR analysis.
( As an Anglophile, I regretted that when we Latins went for the vernacular that we didnt use what the Anglicans had done but invented the clunky New Mass. that practically reveled in flat language and endless experimentation. That evidentally greatly pained the present pope whose brother was a musician and who himself plays Mozart for pleasure. Thank God, we now a slight improvement in the new translatioin and rubics.)
