After reading the article, I'm inclined to wonder if the same sort of thing happens in churches that focus on the divine mercy. Does apathy towards tradition and orthodox understandings set in when one decides that divine punishment is not a matter to be contended with? In other words, do the liberal mainline churches feel free to allow previously taboo behaviors simply because they don't really believe in hell anyway?
I remember reading a brief article by Martin Marty years ago in Christian Century. He argued that almost no one really believes in hell. If they did, they would be much more fervent in trying to protect people from burning forever. Most of us have felt the pain of a match burning our fingers. If we believed that people would be suffering the pain of skin burning over their whole bodies for an eternity, Marty argued, we'd be doing a whole lot more to try and protect people from such suffering -- especially our friends and family. Since he doesn't see this happening even among many of the punishment-in-hell denominations, he concludes that they don't really believe in hell.
I've argued elsewhere (and fairly frequently) that our actions proclaim our faith louder than our words.
At this particular discussion, proclaiming our faith isn't the objective. Was Jonah proclaiming his faith when he went to Nineveh? No, he was forced (finally) to simply go and proclaim the words the Lord instructed him to say, even, likely in his case, when he believed it wouldn't work and perhaps didn't even want it to work personally. It seems he didn't want the Assyrians to be warned.
Or, John the Baptist, did he set out to simply proclaim his own faith? I think not, he set our to prepare the way of the Lord whether the people listened or not, declaring his faith was not the objective.
Or, Peter after Pentecost, was he simply trying to proclaim his faith to the people? No, he wasn't worried about his own faith, he was worried that other people need to be told, with words, what was going on.
Sometimes it's not about us, but what He does and wants done.
