The practice of polygamy is not presently encouraged, but that is not what you implied. You implied that our theology changed, when it hasn't.
Right. God permits polygamy. Revelation! God prohibits polygamy. No change. Right.
We still recognise that the polygamous marriages made during the time the church practiced are completely valid. We hold that there will likely be (new) polygamous marriage in the life to come. We do not practice it for the time being.
Yes, probably if the government permits polygamy, the prophet will get a revelation that God once again approves of it.
Similary, if for some reason the Mormon Church will in future be damaged by prohibiting Gay marriage, the right person will get a revelation that God likes that too. And once again, it will not be a change in theology.
If you want to discuss the topic of blacks and the priesthood, start one. If you are only interested in taunts, I am not interested in responding.
No, do you? I'm just pointing out that the prophet gets whatever revelation he needs to get to protect and advance the church. At this point I wonder whether Joseph Smith would recognize the religion he founded.
I'm 19, and confident that in the next 50 or so years of life I am likely to have there will not be so much as an (official) whisper of the church getting rid of the doctrine that homosexuality is a sin.
I'm 53, and I'm equally confident you're wrong. Others around here can tell you I have a pretty good track record on my guesses. It's because I base my guesses on the empirical system.
Actually I don't know whether they will allow Gay relationships for Mormons, although they might. Pretty soon though they'll stop trying to influence what the rest of society does about it.
