As every gospel scholar knows, the Book of Mormon proves that Joseph Smith was called of God to minister in the prophetic office and to restore the truths of salvation in plainness and perfection.
The Book of Mormon is a volume of holy scripture comparable to the Bible. It contains a record of God’s dealings with the ancient inhabitants of the Americas. It is another testament of Jesus Christ.
It contains the fulness of the gospel, meaning that it is a record of the Lord’s dealings with a people who had the fulness of the gospel, and meaning also that in it is found a summary and a recitation of what all men must believe and do to gain an inheritance in the heavenly kingdom reserved for the Saints.
As the teachings and testimonies of Moses and Isaiah and Peter find place in the Bible, so the parallel preaching and the same Spirit-guided testimonies of Nephi and Alma and Moroni have come down to us in the Book of Mormon.
This American witness of Christ was written upon gold plates which were delivered to Joseph Smith by an angelic ministrant. This ancient record was then translated by the gift and power of God and is now published to the world as the Book of Mormon. (“What Think Ye of the Book of Mormon?” Ensign, Nov. 1983.)
