What reflections might occur to a veteran student of the works of St Thomas Aquinas after reading Jean-Luc Marion’s remarkable book God without Being? Of course, it is not primarily about the thought of Aquinas. But we are persistently encouraged to reject an approach to the question of God which thinks in terms of a concept of ‘Being’, in favour of an acceptance of the reality of God in an economy of ‘Gift’. Thus, one is certainly sent back to the text of Aquinas with provocative questions. For myself, I have to say that I was prompted first of all to return to the magnificent account in the Summa Theologiae of the epistemology of the beatific vision (Section I)—not that Marion himself discusses it (he doesn’t), but his whole approach is a reminder of the radical ‘theocentricity’ of Aquinas’s thought. Next, it proved interesting to compare Marion’s approach with philosophy of religion in the English-speaking context (Section II). Much else might be mentioned, no doubt, but, given that context, the intelligibility of speaking of God either with or without reference to ‘Being’ could not but become questionable (Section III).

Question 12 of the Prima Pars must be one of the finest in the Summa Theologiae. Composed in 1266-67, when St Thomas was teaching at Santa Sabina in Rome, it has no precedent or exact parallel in the rest of his work, although of course he treated the same material in several different places.
