In a sermon, Orson Hyde teaches that the Constitution and Government would one day be in danger of overthrow but the Elders will save it.

It is said that Brother Joseph in his lifetime declared that the Elders of this Church should step forth at a particular time when the Constitution should be in danger, and rescue it, and save it. This may be so; but I do not recollect that he said exactly so. I believe he said something like this—that the time would come when the Constitution and the country would be in danger of an overthrow; and said he, If the Constitution be saved at all, it will be by the Elders of this Church. I believe this is about the language, as nearly as I can recollect it.
