According to Riess and Tickle, early Mormons rarely quoted from the Book of Mormon in their speeches and writings. It was not until the 1980s that it was cited regularly in speeches given by LDS Church leaders at the semiannual General Conferences. In 1982, the LDS Church subtitled the Book of Mormon "another testament of Jesus Christ." LDS leader Boyd K. Packer stated that the scripture now took its place "beside the Old Testament and the New Testament. Riess and Tickle assert that the introduction of this subtitle was intended to emphasize the Christ-centered nature of the Book of Mormon. They assert that the LDS "rediscovery of the Book of Mormon in the late twentieth century is strongly connected to their renewed emphasis on the person and nature of Jesus Christ."
