I think it's more the prinicple of the matter. Yes she should leave and go to a differnet church since, apparently, there is one that is willing to do things differently, but the Catholic church as a whole is ruled by the Vatican, and the fact that they have these hard pressed rules, like the wheat cracker, women can't be priests, etc, is what's the problem. There are more churches that will aree with the one that denounced the communion, than there are those that are willing to work with them.
I agree with her decision to fight this, but at the same time, I disagree with a lot of what I've heard with the Catholic church. It doesn't seem like a true/pure form of Christianity to me. Course, I also grew up in a Penticostal church and, as a result of some things I saw there, don't like/think denominations are a good thing for the church. I've been going to a non deniminational church for over 10 years now and I love it.
