Actually Brigham Young was a plig all the way. It wasn't Brigham Young, but a subsequent infallible prophet who reversed Smith's originally infallible prophecy.
Wouldn't that make the flds the real mormon church and the lds the off shoot?
That's true. It is the FLDS that is the true heir to Smith's teachings, and the "mainline" LDS church the apostates.
Evident on the surface. It amazes me the way LDS argue it.
