Surprised I have to explain: the LDS church started the polygamy thing and then had to renege on that to gain admittance for Utah as a state.
You do not understand our religion that was an ordinance from the Lord, and when the mission was completed the souls who were to enter earth in this fashion, this ordinance of the Lord was no longer needed and will never be re-instated we are in the last dispensation there will be no more dispensation.
