Vail shares the developement of his understanding of Friends. His interests were both historical and contemporary. Good stuff. Here’s a quote:

I sought and found opportunities to inter into dialogue with them and with some scholars from the Church of the Brethren, in hope of clarifying my understanding of the original Quaker vision in the context of a broader “radical Christianity and Christian radicalism.”
