It's not as much of a mess that you might think. I trust the standard works. If leaders agree with me, I quote them.
So you invent your own theology, and cherry-pick the leaders who agree with you.
It's really not any different than any Christian does. Some pick their denomination, others don't pick any at all.
Not only is this completely false, but it's also OFF-TOPIC.
But as usual, this poster knows he cannot defend his bankrupt and indefensible beliefs, and so he has to instead try to attack Christianity (which is OFF-TOPIC), hoping that he can convince readers that it is fault, and that Mormons hopefully wins by "default" (which is fallacious).
When Christians can straighten out all their beliefs, then they will have room to place judgment on us. In the meantime, the core beliefs are basic: 1) Jesus is the Christ, 2)The Church is true, 2) Joseph Smith restored it - the BoM is true.
Again, wrong on many counts:
1) Smith "restored" nothing.
2) Smith was a FALSE prophet.
3) The BoM is a poorly-written piece of fiction which teaches modalism, and monotheism, among other things, neither of which Mormonism teaches.
And no, Christians don't have to do anything to judge Mormonism.
Mormonism has a set of beliefs, and a set of sources which they claim are authoritative to teach those beliefs, and all we (or anyone else, regardless of religious beliefs) have to is compare Mormon beliefs to Mormon authoritative teaches.
In the meantime, I take all church leader's statements to heart. I ponder and pray about them, and I find some are more true than others.
So you deny that they are true "prophets".
"There may be some things that the First Presidency do; that the Apostles do, that cannot for the moment be explained; yet the spirit, the motives that inspire the action can be understood, because each member of the Church has a right to have that measure of the Spirit of God that they can judge as to those who are acting in their interests or otherwise" Lorenzo Snow, "A Serious ordeal, etc.," in Conference Report (October 1898), 54.
Sounds like a recipe for a "god of confusion".
