I'm not certain what you're asking, so I'll just give my reactions to what you wrote. Your post quotes a man who said:

But if it's wrong, it's wrong all the time regardless of the circumstances.

Although I believe this shows a slight lack of sophistication in moral philosophy, I basically agree with him. However, is polygamy a sin? Abraham did it (kind of.) Isaac and Jacob did too. King David did, and his son most certainly did. Aside from bishops needing to be "the husband of one wife", I don't see what the issue is. Why coulndn't anyone marry more than one wife?

But that skirts the larger issue. If something is wrong in one time and place, is it not wrong in all times and places? As I said, I largely agree with that. Animal sacrifice, for instance, is no longer acceptable. Eating pigs, however, is. But let's take the statement, for the most part, at face value. Something that is a sin is always a sin. If that is the case, why do we not follow some of the laws of God's Chosen from the OT? I mean the ones for the nation, like wiping out other nations that worship foreign gods.

But that still isn't the main issue of your post. How much can we question? It seems to me that everyone is going to question everything anyway. I know I did, right before I started down the Catholic path. Even the Orthodox, to some extent, encourage that as "wrestling with God." To be engaged with God in that manner is better that becoming distant from Him. And I think the Church must allow such questions and doubts.

However, the Church can never deviate from the deposit of Truth. As much as questioners deviate from it, they are not Christian. Thus, the main question is how are we going to determine what that Truth is.
