Elevating Joseph Smith above Jesus? You must be getting an incorrect message somehow. We have one Savior, and that is Christ.
Are you CHOOSING to ignore what Mormon leaders have said?
"Now if any of you will deny the plurality of wives, and continue to do so, I promise that you will be damned;
and I will go still further and say, take this revelation, or any other revelation that the Lord has given,
and deny it in your feelings, and I promise that you will be damned.
Brigham Young - JoD 3:266 (July 14, 1855)
