Crystal S. Lewis writes the blog Diary of a Christian Universagnosticostal. In my most recent post here, I made reference to her series of posts on “Hell.”
Crystal has also written a post titled Should Universalism Be a Dirty Word? to which I commend you. [Ed. note April 4, 2014: I can no longer find this page on her site, which is why the link is lined through as broken.] She later posted Websites & Blogs About Christian Unitarian Universalism which obviously offers resources on the subject.
I hasten to add that I am not affiliated with Crystal or any of the organizations she lists on her posts. Nor are you likely to find me supporting everything she or any of them teach – or vice versa. Nevertheless, I thought you might find some of these resources helpful, particularly as they show universalism to be not nearly as uncommon a view among Christians as you might suppose.
