In each case, Purves provides a short biographical sketch and then explores aspects of their works that contribute to pastoral care and shepherding. Although there was wisdom in each, I was particularly drawn to Gregory of Nazianzus, the earliest of them. Purves wrote, "according to Gregory, the pastor is a healer, even more so than the physician for the pastor treats a sickness that is a deeply subtle foe of healing a sickness of the soul" (p. 17).
Also, in the chapter on Gregory, Purves makes this point: "the godly pastor is not only a psychologist and rhetorician, but above all else also must be a theologian" (page 22). I would love to see this wisdom penetrate the pastoral office today.
