It's typical to think that theology is static and permanent. It's not, though. What's true instead is that theology follows sociology. And slowly but surely we are all becoming members of one big society. At the very least media generally, and the Internet in particular, has made world travelers, and culture tourists, of us all.
The world is rapidly changing. And as surely as one day follows the next, Christian theology, as it always has (slavery, anyone?) will change right along with it. As our world grows smaller, our Christianity will grow larger, broader, and more inclusive.
