“[T]he land of Missouri, which is the land which I have appointed and consecrated for the gathering of the saints. Wherefore, this is the land of promise, and the place for the city of Zion. And thus saith the Lord your God, if you will receive wisdom here is wisdom. Behold, the place which is now called Independence is the center place; and a spot for the temple is lying westward, upon a lot which is not far from the courthouse.”
Joseph Smith, Jr. – 20 July 1831, Doctrine and Covenants – Section 57 (Zion, Jackson, MO: The Church of Jesus Christ of Latter-day Saints, 2024 on-line edition), verses 1-3.
