RLDS: Why Was Kirtland Temple Holy?

When Joseph Smith dragged his feet on building the Kirtland Temple, the Lord rebuked him saying,“Ye have sinned against me a very grievous sin in that ye have not considered the great commandment” in the “building of mine house.” (D&C 95:3) The Lord, in fulfillment of Acts 3:19-21, appeared in the temple to accept the temple. This was followed by the appearance of Elijah, who restored the keys of sealing of families and Moses, who restored the keys of the gathering of Israel, yet the RLDS/CofC don't see either as binding on the church. Apostle Orson Hyde was subsequently dispatched to the Holy Land to exercise the keys of the gathering of Judah, which began within two decades thereafter. Why, if the RLDS/CofC was going to ignore these important keys, did the church value the Kirtland Temple? It would be like valuing (as a relic) the cross Jesus was crucified on, while wholeheartedly rejecting the Atonement. It makes little sense. I've wondered about this for years.
