Is the Community of Christ Christian?

So basically Mormonism can be Christian in certain circumstances but not others? What exactly IS Mormonism then? Should we limit it only to LDS? But RLDS claim to be Mormons of a different denomination than LDS. FLDS claim the same, Strangite LDS claim the same, etc. What is Mormonism?

You're going about it backwards - Christianity can have some tarnishing of error and still be Christianity. Seventh Day Adventists, for example, believe in the prophesy of Ellen G White (who was not a prophet) and have all kinds of beliefs about lifestyle and health but are still Christian.

Now, you have to know God to do this. It's easy to put up an idol. That's why doctrines of the Trinity and basic soteriology are so critical.

It's not that Mormonism can be Christian, it's that Christianity can survive some stain of Mormonism.

Why would you even consider it in the first place? You know Mormonism is a cult so why bother with it's derivatives.

The giveaway is in the first line of their statement of belief
Pay attention to

This SCREAMS cult - "we're Christians, look at all these Christian beliefs we hold… by the way this isn't all we believe but if you want to know more then you have to join us"

Their belief statement is designed to lure would-be Christians by deception, and once they've reeled you in they'll pump your brain full of heresy and blasphemy. Satan isn't hiding, Satan is right there in the beginning of their message
