The Bible is the word of God; but not all spiritual truth is found therein. It is well-known that the LDS Church embraces some concepts and doctrines that are found only in LDS scripture. We make two points about this:
1.) There is not a jot of LDS doctrine that contradicts the Bible, despite man’s regular misinterpretation of it.
2.) Mainstream Christians often demand that we defend our extra-Biblical doctrines by using only verses from the Bible, while simultaneously embracing many of their own extra-Biblical doctrines. This is hypocrisy.
Ah, the standard cult response: ‘We don’t need more than one vague Bible reference [to promote baptism for the dead in this case] to support our cultish belief because we have extra-biblical evidence which supercedes the Bible. Good luck with that, heretic. The Bereans knew better than to take that road.
