Your response makes no sense.
You stated “They compliment and support each other” refering to the book of mormon & the Bible.
So does Scientology, the Koran, the Talmud, etc... yet they each have their own way of looking at Jesus & their own prophets. Why is it so important that Mormons be called Christians now, when they were so against the ‘apostates’ to begin with? Just because the BOM supports the Bible, doesn’t mean that the Bible supports the BOM.
