Here's one Q&A that gives us a window into Bell's understanding of what 'evangelical' means and what his 'restoration' might look like:

Q. OK, how would you describe what it is that you believe?

A. I embrace the term evangelical, if by that we mean a belief that we together can actually work for change in the world, caring for the environment, extending to the poor generosity and kindness, a hopeful outlook. That’s a beautiful sort of thing.

[Obviously, this is a very brief interview and Bell has much more to say on the subject. But what is noteworthy in this Q&A is the absence of any theological understanding of the term 'evangelical' by Bell.]
