Radical Jesus blog
When I was a student and a new organizer in Providence, I was blessed to find a lot of mentors among the radical Christians in that city. We did a couple of demonstrations for affordable housing together and prepared for them with prayer, reflection and song. I learned a lot from this, and it was a key step in my developing commitment to radical politics. One of them just shared with me a blog he writes for: http://www.radicaljesus.org/. I encourage folks to check it out.
