Well fortunately, we do have a few pastors that are here. Unfortunately, they don't have a flock to minister to in person, at least as far as I am aware, except for Dowell.
Pastors are in a very difficult predicament. I feel something of the weight of it.
If he tells the truth about what the Bible says then the following will very likely happen.
1. He will get fired, be ridiculed, hated, and scorned, drummed out of his career, experience financial hardship, and likely watch his own family disintegrate.
2. His church will probably explode if anyone actually agrees with him.
3. Broader society will utterly despise him.
4. Certain carnally minded men in the church will think polygamy gives them a free pass to gratify their flesh. These men will wreck their families and make a huge mess.
On the last Day, this pastor will also be commended for his fidelity to Christ. He passed a hard test. God knows that he told the truth because he truly fears Him, and believes, loves, and hopes in Christ. Like Lazarus the beggar, this man will enter and receive the blessings of the Master.
On the other hand, he can just go along to get along, playing ball with the devil by intentionally suppressing truth in unrighteousness. Fearing man more than God, he can compromise with the world, and lie about God's word.
He will remain respectable. He will get to keep his air conditioned office. The paychecks will keep coming. All people will speak well of him.
On the last Day, he will likely hear "Depart from Me into the lake of fire for I never knew you".
Like the rich man, he chose the "good things" of this life over God Himself, and will enter torment.
I don't believe pastors will go to hell for teaching wrongly about polygamy, but the man who ultimately teaches lies because he fears man more than God simply doesn't have true saving faith. He lies about the Bible because he doesn't actually belong to Christ.
The Lord told us to count the cost, and that the man who seeks to save his life will lose it, while the man who loses his life for Christ will save it.
