Theology is not a private subject for theologians only. Nor is it a private subject for professors. Fortunately, there have always been pastors who have understood more about theology than most professors. Nor is theology a private subject of study for pastors. Fortunately, there have repeatedly been congregation members, and often whole congregations, who have pursued theology energetically while their pastors were theological infants or barbarians. Theology is a matter for the Church.
