The Prophet Joseph Smith stood in a unique position as the leader of The Church of Jesus Christ of Latter-day Saints. He held positions of translator, prophet, seer and revelator. He was taught the responsibilities of his calling as he translated ancient scripture - the Book of Mormon and the Bible. He was further instructed concerning his calling as he received revelations contained in the Doctrine and Covenants. This study examines scriptural passages that surely influenced the Prophet's understanding of his own calling. It then illustrates Joseph Smith's view of his calling as evidenced by statements in his writings and discourses. It examines what he understood to be his duties in his position as President of The Church of Jesus Christ of Latter-day Saints and head of the dispensation of the fullness of times.
