I'm a Christian. So when I say that I support gay marriage, most people are either going to assume that I'm a "liberal" or faking the whole Christianity thing. It's like there isn't a middle ground.
I don't know where I stand, honestly. The liberals don't even want me! What I do know is that there are some verses in the Bible that say homosexuality is a sin. There are also verses that say gossip (and much more of these, by the way), gluttony, wearing cotton blends and eating shellfish are sins as well. I don't see anyone lining up to condemn the fat preacher for his sinful lifestyle of eating too much, or arguing that a gossiping couple shouldn't be allowed to adopt, or that Johnny who wears wool pants to work with a tad bit of Spandex for stretch shouldn't be allowed to marry Marie, because they might pass on their evil habits to their children.
So I guess I'm wandering around in the middle ground, right about where Jesus put his disciples when he took a bunch of law-abiding Jewish guys and got them to break all sorts of religious laws. Like not honoring the Sabbath. Then Jesus turns around and says, Yeah...don't worry about that. The Sabbath was a gift to you, not a curse. When it starts being a curse, you gotta let it go. (That's my updated take of Mark 2:27) Jesus wasn't very good about laying down nice black and white lines for us to fit ourselves into.
For example, Jesus didn't ever mention anything positive or negative about homosexuality. He didn't address it at all. But he did spend a lot of time with the sort of folk that "Good Religious People" sneered at and avoided like they were, literally, lepers. The sort of people you secretly thank God that you are NOT like. The kind of people you keep away from your kids. Those were Jesus' friends. He loved them.
I figure anyone that the Christians are shunning is someone I might just want to get to know. If I want to be close to Jesus, that is. And I can't very well love someone while simultaneously cheering that they aren't allowed the same rights as I am, now can I?
