There's no way that mormonism in any way equates with Christianity. There's only one God, not tens of thousands.
And they've been under orders to stress the similarities ever since people like Mittens Romney became eligible for high office. Whereas, if you really study their written material, Christianity is abhorred by the mormons.
2 Corinthians 11:12
And I will keep on doing what I am doing
in order to cut the ground from under those
who want an opportunity to be considered equal
with us in the things they boast about.
