In reply to Robert M Bjornstad.

All denominations are declining per data that is publicly available. The denominations that are losing membership at a frightening pace are those that are theologically liberal (and many of those denominations happen also to be politically liberal). Many, like the Episcopalian church are forecast to disappear completely within 20-30 years. They have succumbed to decades of cultural pressure, which is obviously only getting worse. The denominations that will survive this will be those that stand up against the rapidly declining culture and resist the call to reinterpret or water down the Word of God. Theologically conservative denominations will survive and, I believe, come out on the other side stronger.
