I am not Mormon. I don’t think LDS qualifies as a Christian Church. That said I have always supported LDS in argument with people who are fanatically anti Mormon, many on FR, because LDS was preserving in its members the Christian norms and values that the rest of American Christian sects were shedding and ignoring. It looked to me like God was maintaining a repository of morality in a group that would maintain it even as Christians slipped away. That argument has taken a hit now.
“LDS was preserving in its members the **Christian norms** “
I don’t think you know what that phrase means.
