It is probably true to say that there is no form of intellectual life more unfamiliar to the educated English Catholic than theology. If he were asked to name some topics which he supposed were discussed by theologians he would probably refer to the proofs of the existence of God, transubstantiation, the sacraments-the first of these in the context of ‘Thomism’, the second of apologetics, in school and pulpit, the third in the context of ‘liturgy’. The reference to the pulpit is a considered one; for if lay Catholics are open to the charge of naivety, the responsibility is by no means wholly theirs; can the clergy, and even the professional theologians among them (with some embarrassment I include myself, if only as a theological columnist, in this sub-category) , really claim to be practising theology with energy, fertility, learning and insight?
