And therein lies the crux of the problem. (No pun intended)
Joseph Smith has been proven to be a fraud, therefore, the whole argument is a wash. Without credibility (JS), his claim is without credibility.
And svcw is correct, the Bible is not central to mormons, the BoM is.
Only as sucker bait.
There is NOTHING in the BoM that is central to MORMONism.
Only in the D&C's and the purloined MASONIC rituals is TRUE MORMONism to be found.
