Earlier in the thread you said that Christians and Mormons don't really believe very different things. This struck me as odd, as I just read a blog post by Al Mohler, a very conservative Baptist with whom I disagree about a lot (particularly Genesis, age of Earth, etc), in which he went on and on about how Mormons and Christians believe very different things. I'm not particularly interested in his point ("Is it okay to vote for Mitt Romney?!?!?!"), but I was hoping you could respond to his points about the differences, some of which I've quoted below.
Mormonism starts with an understanding of God that rejects both monotheism and the Christian doctrine of the Trinity. The Mormon concept of God includes many gods, not one. Furthermore, Mormonism teaches that we are now what God once was and are becoming what He now is. The Mormon doctrine of sin is not that of biblical Christianity, nor is its teaching concerning salvation. Rather than teaching that the death of Christ is alone sufficient for the forgiveness of sins, Mormonism presents a scheme of salvation that amounts to the progressive deification of the believer. According to Mormonism, sinners are not justified by faith alone, but also by works of righteousness and obedience. Mormonism’s teachings concerning Jesus Christ start with a radically different understanding of the Virgin Birth and proceed to a fundamentally different understanding of Christ’s work of salvation.
So, uh, thoughts?
