Mormons are claiming to be a “restored” church. That means the consider themselves to be a superset of “failed” Christianity. Yet they claim to be a subset of the Christian brotherhood.
Claiming to be a superset and subset at the same time is disingenuous, it is an attempt to confuse the gullible.
I understand your confusion. The Mormons certainly claim to be a superset, but they do not claim to be a subset. They do not claim to be a branch of the Catholic or any other church. They just like any other church, worth mentioning, claim to be the one true Church. Just like the Catholics claim to be the one true Church or did you miss that part?
“Since you didn’t answer the other questions I will assume that you agreed with my replies.”
No, that is not the case. I simply have a busy life and don’t always have time to parse things out for a reply.
