The Independence temple prophecy
Doctrine and Covenants 84 says the New Jerusalem temple in Missouri would be reared in this generation. Official LDS history confirms it was not built at that time.
The time marker is the issue
D&C 84 speaks of a temple in New Jerusalem beginning at the Missouri temple lot and says it would be reared in this generation. It also says that generation would not all pass away before the house was built and filled with glory.
The point is not whether Latter-day Saints later expected a future temple. The issue is whether a future temple can satisfy a time-bound promise to the 1832 generation.
Official LDS history confirms the nonfulfillment
Official LDS material says the Saints fled Jackson County before they could build the temple, and that neither the city nor the temple was built at that time.
D&C 124 can explain why the Saints were excused from the commandment. Being excused from a commandment is not the same as the prophecy being fulfilled.
A later temple would not answer the wording
A future temple in Independence may be part of LDS expectation, but D&C 84 tied the promise to the generation receiving the revelation. A later fulfillment has to explain the original time marker, not merely point to an eventual possibility.
That is why the page treats the issue as a prophetic reliability test. The question is not whether Latter-day Saints still hope for a temple. The question is whether the 1832 revelation happened as stated.
Conditional explanations have limits
LDS responses often appeal to persecution, expulsion, and later revelation. Those facts explain why the Saints did not build the temple. They do not by themselves convert the earlier prophetic statement into a fulfilled prophecy.
If a time-bound prophecy can be preserved by redefining the time marker after nonfulfillment, the public test of prophecy becomes difficult to apply at all.
