I think perverting scripture, believing in false prophets, etc., is a lot more important-in the grand scheme of themes-than whether these churches are becoming Episcopalianism Lite.
Accepting false doctrines are how churches fall. I don’t think that we are condemned for not being able to discern truth from error, but that doesn’t change that, when you accept any form of false gospel, you put yourself at risk of being deceived entirely.
