He writes:
The church fathers clearly saw themselves standing in direct continuity with the primitive church in the book of Acts. In fact, the subject of demons and the practice of exorcism are more prominent in the post-apostolic church than in the church of the New Testament. Far from exhibiting a decreasing interest in the phenomena of the unseen world, the pre-Nicene church enthusiastically embraced these super- natural aspects of the tradition. Before the fourth century, however, the views of the church fathers were characterized by some restraint; afterA.D. 325 little of the former sobriety remained.
I do think he overstates the enthusiasm post-Nicea. I always read the evidence the other way. Once James 5 became a sacrament, there was little point to use it for healing.
He documents the church fathers:
See, for example, Ignatius, Epistle to the Philadelphians, 7:1, Kirsopp Lake, ed., Apostolic Fathers, Loeb Classical Library, 2 vols., Cambridge: Harvard Univer-
sity Press, 1:247; the Didache 11, 7-12, 1:327; the Shepherd of lfermas, Mandate11, 7-16, 2:121-23. This article will exclude all references to gifts of the Spirit and miracles which may be biblical only. See, for example, Athenagoras, A Plea for the Christians (about A.D. 177), 7, Alexander Roberts and James Donaldson, eds., The Ante-Nicene Fathers, Grand Rapids: Eerdmans, 1979, hereafter, ANF, 2:132, and Clement of Alexandria (about A.D. 202), The Stomata, 4.21, ANF, 2 :433-34-where the gifts that are mentioned are not obviously contemporary.
