The Catholic faith doesn't work for people who see things in absolute terms. It's far too messy, far too open to discussion.

Oh, sure. The epitome of enlightened consensus. Except that it's the only significant Christian denomination (overwhelmingly the biggest of course) that puts itself above the World Council of Churches - an inevitable consequence of its intransigent (in fact bigoted) teaching that no church except itself is a church at all, a line reiterated in unequivocal terms by the one-time Cardinal Ratzinger when he was chief exec of the Congregation for the Doctrine of the Faith.
