Recent decades have seen Evangelical theology express a renewed interest in the Church Fathers. This is all well and good. Rooted in the Bible, Evangelicalism at its best has always thought of itself in continuity with the apostolic gospel as it was proclaimed and taught in the early church, the Medieval period, the Protestant Reformation, and Evangelical revivals up to the present day. But in this positive retrieval, there is also the danger of an idealization of the Fathers (as if they were always right and always working with pure motives) and a wholesale and unwarranted appreciation of “tradition” (as if it was a monolithic body that is organically related to Scripture). In order to both affirm the Evangelical interest in the Fathers and suggest some caveats in practising it, this session will suggest five principles that can be useful to bear in mind.
