Did Joseph Smith’s Missouri temple prophecy fail?

The short answer

Doctrine and Covenants 84 says the temple in Missouri would be built in “this generation.” The temple identified there remains unbuilt. Later revelations postponed Zion’s redemption and accepted the offerings of people prevented by enemies from building in Jackson County. The faithful explanation reads the undertaking with those later instructions. The timing language remains a fair question.

What does D&C 84 say?

The September 1832 revelation says the temple in Jackson County, Missouri, would be built in “this generation.” It was not built during the lifetime of those who heard the revelation. The text does not say “if the Saints are obedient.” D&C 84 and its manuscript

What happened later?

The Saints were expelled from Jackson County in 1833. D&C 105 postponed Zion’s redemption in 1834 and cited the people’s need for preparation and unity. In 1841, D&C 124 released those diligently prevented by enemies from building the city and house. Orson Pratt still expected the 1832 generation to witness construction in 1870. Applying the release to the earlier prediction about timing is a further interpretive step. D&C 105 · D&C 124:49–55 · Pratt, 1870

A reply you can use

“The original generation language is difficult. I read the promise alongside the conditional temple instruction in D&C 97, the postponement in 1834, and the release in 1841. That is the basis for my belief that the undertaking changed under those circumstances. I still need to account for the earlier wording.” D&C 97:15–18
