The founder of Mormonism. He is often referred to as The Prophet. Almost all LDS teachings originated with him. “Joseph Smith, the Prophet and Seer of the Lord, has done more, save Jesus only, for the salvation of men in this world, than any other man that ever lived in it.” (D&C 135:3) Testifying that Joseph Smith is the true prophet is an essential component in being a member of the LDS Church.
