You think? just ask Presiding Bishop Jefferts Schori of The Episcopal Church about that "faith once delivered to the saints." According to her there's room for mormons, hindus, pagans, zoroastrians, whatever, all just "different pathways" to the same goal. Or ask the United Church of Christ, which has officially declined to witness Jesus Christ as God incarnate.
This is why attacks on Mormons on religious grounds rings hollow as a dead log.
I’m not attacking anybody. My firm position is that a candidate who opines about who is and who is not a Christian makes me want to vomit.
However, a candidate who opines that the LDS phenomenon IS Christian in the usual sense is a dope.
There is abundant information from the founders of the LDS whatever-it-is on what they thought about Christianity for anyone who cares to look.
A better way to say it is that LDS is about as Christian ans bishopess Schorl.
