Brian Gorman started a blog topic (http://brianjgorman.wordpress.com/ "Drawing and Erasing Lines") about what makes a Christian a Christian, among other things. The two of us and some others have an interesting conversation and exchange going on. Feel free to check it out and make some comments if you're interested.
I'm focusing more on interspirituality and cultural critique of the bible (to sort out what is myth/story that points to truth (or contains truth) instead of actually BEING the truth itself, for example.
I find it a really fun conversation - I hope someone else checks it out and finds it interesting!
