Maybe this will give you a little comfort. Before a person like me ever sees such things accepted in my church, or sees my own church descend into full blown liberal heresies, I will join the Catholic Church. I've already decided that. I agree with 85% of Catholicism, but the 15% I disagree with are the doozies. I will move toward orthodoxy, liturgy, and confessional faith before I will ever find myself in communion with any of the liberal extremes that are destroying certain Protestant denominations (Episcopalian, United Methodist and ELCA come to mind). It's just that Mary thing I'll have to figure out how to deal with if it ever comes to that...because right now, I can't deal with it.
It would not suprise me if more of the Mainline Protestant churches end up imploding because of these hersies you describe. God Bless you on speaking the truth about these churches.
A very honest post by you and you did point out a truth that sometimes gets lost on this forum, that historic Protestantism and Catholicism agree on way more than we disagree on. I think we all need to remember that as we combat what Pope Benedict calls the “dictatorship of relativism” and the radical Islamist who “devoid faith from reason”.
This Catholic thanks you for the charitable post, which was charitable even on the Marian dogmas you struggle with.
