No Joel, No!
NO JOEL.. No! Mormonism is not Christian at all - it is not Christian doctrine to deny the Trinity, to proclaim that the god who rules this earth (and who we are to worship) was once a man and who lives now on a planet encircling a star called Kolob; that Jesus was conceived by a sexual union between God and Mary... that the Bible has been superseded by the book of Mormon; that Jesus' death and resurrection merely secured an opportunity to be saved if people will work for it.
Every Mormon needs to hear and embrace the true Gospel, not be affirmed as already being a Christian, especially by someone as prominent as yourself Joel. If you don't know what you are talking about say nothing - admit that you have not studied what Mormonism teaches - but PLEASE don't affirm the Mormon faith as Christian. Mormonism is the most polytheistic faith on the planet.
It is not at all loving to let the wolves roam free amongst the flock Joel and you just did that through your words. You also have undermined all the many ministries out there (many of them former Mormons) whose seek to win LDS people to the Lord.
