Explanation:
The individual who identified himself as "a disciple of Jesus Christ," a "pure descendant of Lehi" was Moroni. This character is a pivotal figure within the Book of Mormon, an essential religious text for members of the Church of Jesus Christ of Latter-day Saints, often known as the Mormons. Moroni is described as the last of the Nephites, a people said to be descendants of Lehi who journeyed from the Middle East to the Americas around 500 BCE and the son of the prophet Mormon. He is also credited with delivering the golden plates to Joseph Smith, which became the foundation of the Book of Mormon.
