Does priesthood differ between LDS and FLDS?

ABSOLUTELY!!! The FLDS have broken off from the LDS. Try this agy. The FLDS believe that the LDS are wrong about things or they are a "dead tree". Now if the tree is already dead, can you take a branch from it and make it live? NO! Therefore, if the FLDS are correct that the LDS are wrong, then they too are wrong because the "broke the branch off" from the LDS.
