Some academic subject matters have a quaintly old-fashioned ring-‘moral sciences’ for example, or ‘natural philosophy’. ‘Practical theology’ has a similar odd sound today. To the theological outsider is must sound remarkably like a contradiction in terms, whilst to the professional theologian it may carry undertones of an unscholarly pragmatism or a tendency towards liberal theology. Yet perhaps the juxtaposition of these two terms is an important one. It may, by its oddity, encourage us to ask the question, ‘Is practical theology possible?’ This would be a question similar to the familiar one about the possibility of metaphysics. It is asking for a formal definition of the subject matter which will meet adequate criteria of meaning, consistency and relationship to other disciplines whose status is not in doubt. In this paper I shall attempt some answers to this question of possibility.
