The only Piskies who are interested in swimming the Tiber are the 'high churchers' - the low churchers and the Evangelicals are not coming. It would be a total waste of time for high churchers to go to your typical RCIA class, as they already subscribe to 99 and 94/100ths of Catholic doctrine, and in many cases are 'more Roman than Rome', especially since VCII.
In fact, that's the reason that more liberal Catholics are having ten fits about welcoming the Anglicans . . . because these guys are extremely orthodox and conservative and will not support guitar masses, ordination of women, liturgical dance, or fuzzy theology.
When we visited our parish for the first time, we met with the rector and he gave us a number of books to read. When we met with him again, it was plain that the only points on which we had any substantial difference were the validity of Anglican Orders and the supremacy of the Pope. That's true of most high churchers. So we evinced our readiness to adopt the Catholic view . . . I observed that 'by their fruits shall ye know them' and Anglican orders clearly had not worked out or protected that denomination from error, and that Papal supremacy prevented exactly the sort of nonsense that GC 2003 created . . . in other words, adult leadership is a good thing. As my husband said, "We can deal."
We did not go through RCIA and were received into the communion and confirmed by the rector, with the Sunday School director acting as our sponsor.
Besides, we would have annoyed the heck out of everybody else in RCIA talking about finer points of this and that and what the Church Fathers said, while they were learning stuff that we learned in Sunday School 30 years ago.
As a Lutheran, I don’t have much of a dog in this fight except for maybe a home for the refuges of the ELCA who won’t go LCMS for anything.
But going strictly by the old canons, this is problematic at best. Not that some of those have been followed for a thousand years or so.
I think the Archbishop is saying that if someone wants to be Catholic, then they should be Catholic all they way.
We have had for many years Anglicans who pretend to be Catholics (the “more Catholic than the Pope” types). Now we will have Catholics who pretend to be Anglicans (they were the vestments and use the a modified BCP, but they believe all that Rome teaches, even those things Anglicanism rejects).
