Quite simply, Christians don't accept the book or Mormon because then they would be Mormons, not Christians!

There are probably plenty of converts who have crossed over. I know plenty of people who have switched between major faiths.

The difference is whether you're talking about individuals, who demonstrably can come to accept the BOM, or whether you mean Christianity as a whole.

Christianity as a whole will never accept the BOM. That's not the way religion works. You have to remember that religion is not about truth, it's about definition. Christianity is defined by a set of beliefs about life and the heavens. Change the beliefs and the religion of Christianity is gone.

Bottom line: religions begin with a set definition. Change the definition and it's a new religion with a new definition. People don't like change, religion abhores it.
