You can choose to believe that Mormon leaders changed the doctrine on polygamy because (i) God told them to, or (ii) response to political pressure.
That’s your choice. What’s your point? That God would never order His people to conform to a nation’s law for their safety, well-being, and progress?
god, according to Smith in 132 verse 4, stated that not to abide by that covenant they would be damned. Clearly that was practiced by Smith in earnestness with god's direction contrary to the law of the land. Polygamy was a (if not the) major force driving their rejection and forcing their move to Utah. So the safety, well being and progress didn't apply to his people then, but suddenly 47 years later it did? Why would god change his mind in that short of period?
