I don't say this lightly, but the matter is so public that I don't see how my commenting makes things worse...
Our Anglican brothers and sisters have been going through an agony these last few months, and the ordeal is not over. The latest, for those who may not keep up on these things, is that the worldwide Anglican Communion has given the U.S. Anglican body something of an ultimatum: no more dallying with blessing gay unions or any such ambiguity on marriage, and no more bishops who are in a same-sex relationship. (I haven't seen anything about other clergy, but I think the point is clear enough.) The rest of the Anglican primates (chief bishops from various nations and regions) have assigned a date, a kind of deadline.
I have refrained from commenting on this, since (a) the Catholic Church has its own ordeals and (b) I'm not Anglican or Episcopalian (for those who wonder about the distinction between these terms: basically, "Episcopal" is the U.S. "version" of Anglican, in the main--you do find congregations and associations that specifically call themselves "Anglican" in the U.S., which seems to be a point of emphasis, rather as "traditional" often is among Catholics).
The trajectory of this drama seems clear enough, I think: either those pursuing a "reinterpretation" of Scripture and Tradition will back up, or there will be a schism. In today's Washington Post, several "liberal" bishops say they prefer schism. Even if there should be a "backing up," the question is, will it be permanent or will there be yet more struggles down the road?
Now, the punchline: for all those who want the Catholic Church to "rethink" her ancient teachings and constant tradition, in all those areas where they rub painfully against contemporary expectations and desires . . .
What the Anglican Church is going through -- that's where it would lead. Only it would be ten times worse (Anglican Communion = less than 100 million worldwide; Catholic Church = over 1 billion.)
