False Prophecies of Mormonism Moroni the Fulfillment of Scripture?

Moroni the Fulfillment of Scripture?

Joseph Smith’s Commentary on the Bible, pg 225; “The angel flying through the midst of heaven: Moroni delivered the Book of Mormon.”

Revelation 14:6; “And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people.”

How could Moroni be the fulfillment of a future event about the tribulation in 1830?
