so many mormons, so many mormon teachings, the problem is that what mormons believe cannot be identified.
one mormon says this, another mormon says that. then, most of the mormons say only the current president’s teachings are official mormon beliefs. that creates the problem of what about all of the things the current president does not address? are those subjects outside of mormon teaching; or, are the previous presidents’ teachings on those subjects definitive? how long are a president’s teachings part of the mormon faith? only until another president contradicts the previous presidents’ teachings.
for catholics, i think it should be sufficient that we know, understand and teach our children and others who have little knowledge of our faith that the mormons believe in a different God than catholics, mormons believe in a different Jesus Christ than catholics, mormons believe in different sacraments than catholics and mormons believe in different scriptures than catholics.
that is what we catholics should first and foremost make clear when addressing the mormon faith. the mormon faith bears little resemblance to the catholic faith, different God, different Jesus, etc.
