At the present time the Church is frequently exhorted to give an ethical lead. Yet what would be the nature of such direction—the dissemination of practical wisdom from the Scriptures, the provision of a blue-print for the realisation of the Kingdom of God on earth, or just emotional encouragement to moral effort? Theological colleges offer courses on ‘Christian Ethics’, and for certain degrees there are papers bearing this title, yet what exactly is the nature of the discipline? Is it any more than the retailing of the moral judgments of distinguished Christians in the past, and information concerning certain important areas of life in regard to which Christians ought to come to some sort of practical decision? Is Christian Ethics a discipline at all, or just an unmapped, and possibly an unmappable, field between dogmatics and practical theology?
