New annulment rules are welcome but they could yet be easily abused
The Catholic Church now has a job ahead of itself explaining to people its new annulment procedures. I've never heard the circumstances under which a marriage may be annulled formally explained. I doubt if very many others have heard it explained either.
For the most part, what information you do pick up about it is by a kind of osmosis. For example, that non-consummation is a ground for annulment. You hear every now and then the accusation that an annulment is 'divorce, Catholic-style'.
If you've been paying attention more than most, you might have heard that for years it was easier to get an annulment if you live in America than in most other countries. Or that even within America, you could get an annulment in one diocese more easily than in another.
