Pardon me friend but not to be rude and sorry friend but some of this stuff might come across as harsh but for your safety and to be clear. the book of mormon does contradict the bible a lot, in fact the bible itself says in Galatians 1:6-9 that if an angel from heaven or even one of the apostles preached another gospel, let them be condemned, and so that would be joseph smith (who has been claimed to have received the book of mormon from an angel) and the way the book of mormon dismisses all it's contradictions is by saying that the bible has been changed but we know this isn't true because of the thousands of manuscripts we have of the bible proving the bible to be the same. So definitely do not treat the book of mormon as God breathed scripture, the bible itself affirms it to be accursed, and so we should be treating the 66 canonical books of the bible (Genesis to Revelation) as the word of God only. hope this was of help though friend and i recommend the expedition bibles "Test of a Prophet" video on the book of mormon for more info on why it's false.
