Islam also believes the Bible to be the word of God with similar qualifiers....
that doesn't make it a Christian faith
it also believes the Torah is the word of God, but that doesn't make it a Jewish faith - -
and most Jews believe the Old Testament portion of the Bible...
I think most monotheistic religions accept that the Bible to some extent is the word of God...
Someone can self-identify however they choose, that doesn't mean that others will see them the same way as they see themselves.
I guess this all depends on how you define Christian. For me it is a religion centered around the belief in Jesus Christ, that he is the son of God and that he died for our sins.
If so than the LDS denomination (now you can shut up Dala) is clearly Christian.
