This is the book on Rufus Jones we've needed for a long time. Helen Holt has given us a beautifully written, compact yet impressively comprehensive introduction to one of the most influential Quakers of the twentieth century. Jones' thinking is clearly articulated, and Holt does not shy away from critiquing Jones when he is less than clear or cogent. Holt also offers what Jones neglected to provide: a practical guide to the mystical path he extolled in his life and work. Highly recommended to anyone seeking to better understand the roots of the modern Quaker way.
