And who made you the arbiter of who is Christian and who isn't?
I think these people would disagree with you:
Glenn Beck's Amazing Grace Moment at Revival
An elderly woman needed a doctor in one of the upper levels - at first we all thought the hollering were protesters, but it becomes obvious that it is something else when people start screaming "doctor." While the paramedics rush up there all 8,000 of us are just sort of sitting in silence, when Glenn starts to hum Amazing Grace ... and the crowd starts humming and softly singing with him. It was a truly beautiful and moving experience.
I do not judge his heart, that is God’s place, but I can and do judge his theology. I was Mormon and I know, without a doubt, that Mormon theology is diametrically opposed to Christianity. The difference is beyond comparison.
And I am surprised to see a story with Beck humming Amazing Grace as the LDS do not believe in personal salvation by Grace, they think it the idea that we are saved (back into the presence of God the Father) by grace and not our works is arrogance. I can provide quotes if you like.
