The Church is Infallible

Journal of Discourses 24:185;There has been no lack about this work. Its principles have withstood all that has been brought against them. They stand unshaken because they are founded on eternal truth. The whole clergy of the world may array themselves against them, as they have to a certain extent; they may endeavor to controvert these principles, but they are founded on truth and they cannot be overturned. Not a single principle that has been declared or been testified to by the Elders of this Church from the beginning up to the present time can be assailed successfully by any religionist, nor by scientific men, because they are impregnable, having had their origin in God…There are no mistakes to be corrected connected with it, either with its doctrine, with its organization, or, with its movement.

This prophecy was given by George Q. Cannon on Sunday, July 15, 1883.  It would be proven a false prophecy less than seven years later by the Edmunds-Tucker Act of 1890 which prohibits polygamy.  It may seem that this is excluded because he said “nothing can be assailed up to this present time”.  The truth is that if it originated from God it wouldn’t have been overturned.
