That Joe Smith is a "true prophet" is an LDS belief.
It is not MY belief.
I figure brer Smith to have been a charlatan and an opportunist.
“That Joe Smith is a “true prophet” is an LDS belief.”
And although we disagree over whether it is a true belief or not, the general principle I stated (If you reject a true prophet you also reject Christ) still holds.
Would you agree that if somebody rejects Noah or Abraham or Moses, or Peter as false prophets and think they accept Christ that they are fooling themselves?
