There is a particular comment you should see from Marion Romney who agrees this is the proper lds teaching. Marion was George Romney's cousin, Mitt's 2nd cousin. FYI
"As man is, God once was; as God is, man may become."
If god was once man and became god he was born of sin and therefore is not perfect. In addition that god was not the creator so therefor he was created by a higher god? Polytheism?
So open to all Republicans who call themselves Christians, The God of Christianity calls you to defend your faith and take a stand. Life on earth is too short to push for a political agenda. You must defy the GOP and vote in a true Christian candidate.
