Well, not just Joseph Smith...but any Mormon who dead-dunks you by proxy & puts you on the temple assembly line religious ritual to do that
(ya need to understand that if Mormonism...just a minute fraction of the entire world...has to "save" the world via proxy baptisms, that nothing short of a massive non-stop dunking enterprise will do...and even then...they'll come far short of even just attempting to "save" everyone who is living now)
One of the fave statements made by most of the Mormon "prophets" & "apostles" is to reference an out-of-context OT verse and applying it to themselves as "saviors" (plural) on Mt. Zion ("Zion" to them = Lds church)
You're saying that same Jesus,' God's only Son's torture and death on the cross, isn't necessary - at least not to Mormons?
All I need is Joseph Smith and other Mormons being "baptized" for me, gets me into heaven?
So Jesus really wasn't needed? Not only did He not need to be sacrificed and crucified on the cross, we just needed to wait for Joseph Smith, who did it all?
Gee, that's not what I learned in Sunday School.
