Detractors of the Church often like to throw scripture bombs at us thinking that they can somehow prove to us that we are wrong and blow up our testimonies. this can sometimes work with members who do not have much depth to their beliefs but for any true Latter-Day Saint with a real testimony of the gospel, these efforts can prove futile at best, and often, actually help boost our faith in the restored gospel. one such 'Bomb' that is often thrown our way is Galatians 1:8, which speaks of havens and other gospels. the implication is that Moroni was a false messenger and the resulting Book of Mormon is evil.
