Well, it is more than likely a conflict based on scripture, but again, not knowing their doctrine and seeing how flawed the CC's views are, I am uncertain as well.
I disagree. It isn't self defeating. If people don't want to attend your church because of your teaching, the heck with it. That's how it should be. Church-goers should not compromise the sanctity of their worship to please a group or groups of people. If a so-called religious person is just that and views the Bible as authority, he should reject certain things regardless of how people view him. Even without the Bible, people in general have moral boundaries that they will not cross.
Respect starts with both sides -- pro-SSM people ought to respect the fact that everyone isn't going to be on board with that. Religious people ought to stop trying to makes laws banning it.
You're right, they should not be passing judgment. Agree 100%.
However, if they're taking a stand on this issue, I don't see how that's judging others. But to your point, I have read the CC calling people disordered and other incendiary terms. They ought to just keep their mouths shut.
