There are only two churches per Mormonism: the Church of the Lamb of God (headquarters Salt Lake City); all other churches are the Church of the Devil.
Book of Mormon, 1 Nephi 14:10
And he said unto me: Behold there are save two churches only; the one is the church of the Lamb of God, and the other is the church of the devil; wherefore, whoso belongeth not to the church of the Lamb of God belongeth to that great church which is the mother of abominations; and she is the harlot of all the earth.
The only principle upon which they judge me [Joseph Smith] is by comparing my acts with the foolish traditions of their fathers and nonsensical teachings of hireling priests, whose object and aim were to keep the people in ignorance for the sake of filthy lucre; or as the prophet says, to feed themselves, not the flock.

What is it that inspires professors of Christianity generally with a hope of salvation? It is that smooth, sophisticated influence of the devil, by which he deceives the whole world.
