The Manti Temple of The Church of Jesus Christ of Latter-day Saints is one of the few temples without a statue of the angel Moroni on top. The only time an angel has been seen up there is during the Mormon Miracle Pageant and that one is live.
The late Temple President Ruel E. Christensen, said he supposed an angel with a trumpet to his lips, with his robes blowing in the evening breeze as portrayed in a wonderful scene in the pageant, might suggest why the tower was finished with a platform instead of a spire on the tower.
Due to the fact that there is usually a breeze, sometimes a strong one, there is a rod on the platform for the live “angel” to take hold of and steady himself. A former “angel” commented it is a “wondrous adventure” to be on the top of the temple during a rain storm.
Moroni was a prophet in the Book of Mormon. He lived on the ancient American continent. As a mortal, he completed the compilation and writing of the Book of Mormon. Over 1,000 years later, he ministered to Joseph Smith as a resurrected being. It was part of the responsibility given to him to care for the Book of Mormon.
Moroni counseled with Joseph Smith during several appearances. He instructed Joseph Smith, testified to the Three Witnesses of the Book of Mormon, and otherwise assisted in the work of restoring the gospel, until the Book of Mormon was published in 1830.
There are nine temples in the world that do not have a statue: Paris, Cardston, Hamilton, Laie, Logan, Manti, Mesa, Oakland and St. George.
