Well, gee, there ya go again.
It was not the LDS that first referred to themselves as Mormon - and within the congrations, they still don't - they are LDS.
Mormon was a name hung on them by outsiders, in reference to the Book of Mormon.
Of course, they also beleive in, read and study the Bible from cover to cover - so hmmmmmmmm?
And you believe in the Bible “as far as it is translated correctly”...
Not exactly a vote of Confidence in the word and abilities of God.
Of course from the LDS perspective God is only human...
And stop using the “them” and “they” be proud enough to use “we”...
