The LDS routinely engages in knowing, fraudulent behavior, such as removing from their websites claims about the Book of Abraham that get debunked. The LDS even teaches missionaries how to lie, which they call giving people milk before meat. Hiding their doctrines and misleading people is part of their culture.
This isn’t like challenging the Baptists to prove child baptism isn’t valid. The LDS is actually a Church of fraudsters.
I have wondered about the lying allegation you make. I had a friend say to me some years ago that LDS children grow up being promised that when our Constitution is “hanging by a thread” the Church will save it.
Well I have talked about the psychological coping mechanism of cognitive dissonance and this is an example of it. The Church’s actions speak louder than those words.
The bible does make reference to the issue of milk and meat but absolutely does not equate milk with lies. Rather the milk refers to foundational scripture which does not require deep thinking to understand. For “babies” in other words. Imho.
Mormonism is a “pay as you go” religion. You don’t pay, you don’t go.
I read somewhere that Joseph Smith actually laughed to see that he was leading so many people astray at the end of his life!
