In this lively response to Scott McKnight’s take on Russ Moore’s review of the movie Walk the Line—McKnight, McLaren, and McAuthenticity—Moore compares the early Cash after his conversion to the early Augustine [presumably prior to the earth-shattering illumination that came when, in the mid-390s, Augustine realized that the entire Christian life is sheer gift] and Brian McLaren to Arius. A good read and response!
