Solely your opinion, not supported by facts. I am sure that Elsie can show that the Mormons rejected both Catholics and Protestant alike.
I posted a question in post 293 concerning the WHY this is so important to the Roman Catholic church. Perhaps you are willing to explain.
There you go again; making a vague assertion with NO evidence being shown.
