So according to your logic those who are nominally Catholic and leave Catholicism to become a believer in Manichaeism (or Marcionism or others) are still Catholic? Are you really trying to find some way of making Mormons into Protestants, consistent with how you would define a Catholic?
and used the KJV for portions of the BOM
Which is far closer to the Catholic DRB than the NIV, but anyway, according to your logic the KJV must distinctively teach Mormonism, or when the devil quotes Scripture (because he knows where the power is) then Scripture is impunged by his misuse of it?
Many protestants and prots refuse to acknowledge the roots of Mormonism in protestant ism due to "bizarre" beliefs. How do you think you all appear to the only real Christians (Catholics) with your bizarre denials of basic Catholic doctrines.
From where we sit you all are on the exact same level.
Heresy is heresy.
