A reasonable person would think that ONE of these 'truths' would be to EXPOSE just WHAT the PRESBYTERIAN were doing that Joseph Smith 'learned' they were teaching UNTRUTHs.
But, alas, we will NOT be told what it is by ANY Mormon on these threads.
That's just another one of their secrets.
As a Catholic, I can identify where I disagree with Protestantism and Protestants can identify where they disagree with Catholicism. NONE of this is done in secret and I know of very few Catholics or Protestants anymore who believe that the others are going to Hell for what they do or don't believe.
But not so with Mormons; when confronted with questions they don't want to answer, you will be accused of "mocking" Mormonism.
