Divine Authority or the Question: Was Joseph Smith Sent of God, pg. 3; “If the Latter-day Saints are not what they profess to be, one thing is certain, that no one ever will be able to confute their doctrine by the scriptures; however imperfect the people may be, their doctrine is infallible. Can this be said of any other people who have existed on the eastern hemisphere during the last 1700 years? No.”
1 Corinthians 1:21; “For after that in the wisdom of God the world by wisdom knew not God, it pleased God by the foolishness of preaching to save them that believe.”
This is obviously a lie. The D&C used to be the Book of Commandments which have thousands of changes made to it and the Book of Mormon having almost 4,000 changes made.
