Reconsidering Aquinas as Postliberal Theologian

RECONSIDERING AQUINAS AS POSTLIBERAL THEOLOGIAN FREDERICK J. CROSSON University of Notre Dame Notre Dame, Indiana IN A RECENT issue of this journal 1 Bruce Marshall argued that the position of Thomas Aquinas on faith and reasonin particular on the meaning of assertions about God-can be read as fundamentally convergent with that of the contemporary theologian, George Lindbeck. The claim is striking because , as Marshall acknowledges, the traditional reading of Aquinas is quite different. Traditionally-Gilson is Marshall's example -it has been thought that the conclusion of a demonstration of God's existence or unity could be true, could correspond to reality, quite independently of the religious doctrines concerning the revealed mysteries of the Godhead. But Marshall argues that, in fact, the texts of Aquinas explicitly deny that the non-believer is really succeeding in talking about God at all. The claim is a challenging one, and one from which there seems much to learn, because it is not only bold-and so promises a significant shift in the traditional understanding of Aquinas's meaning-but confronts many of the texts which seem to warrant that traditional understanding. Even if his reading is wrong, which I believe it is, there is benefit in thinking through the reasons why it is wrong and in clarifying not only what Aquinas taught but also what is at issue. I propose to do three things: first, to state the interpretation which Marshall, enlarging on Lindbeck, wants to give of the 1 Bruce D. Marshall, "Aquinas as Postliberal Theologian," The Thomist 53 (July 89) : 353-402. The article is followed by George Lindbeck, "Response to Bruce Marshall," 403-406. 481 482 FREDERICK J. CROSSON position of Aquinas on the possibility of natural knowledge of God; second, to examine several instances of Marshall's reading which are integral to his arguments but which I think are wrong, i.e., misconstrue the texts he is dealing with; third, to reflect briefly on one of the larger issues which seem to me involved in the questions here discussed, namely the commensurability of the teachings of the major religious traditions. I In Lindbeck's view,2 the propositions about God (or "the Ultimate Mystery") which religious doctrines assert can have " ontological truth " or correspond to reality only if the categories in terms of which those propositions are formulated are adequate to express that reality. This condition may be called the " categorial truth " of the doctrine, and " can thus be described as potential ontological truth, ... a religion has this kind of truth when its ' categories ' are capable of being used to describe what is ultimately real" (359).3 The categorial truth of religious doctrine is thus a necessary condition for its teachings to be "ontologically true," i.e., to correspond to what is. But it is not a sufficient condition. The categories employed by the teachings must be used in the proper way: the composing and dividing of the categories (e.g., "Father," "person," "nature") must be a composing and dividing which asserts what, according to the religious doctrine, really is combined and separated. But for the utterances 4 of a believer to be ontologically true, they 2 George Lindbeck, The Nature of Doctrine: Religion and Theology in a Postliberal Age (Philadelphia: Westminster, 1984). 3 Page numbers without other citation will be to Marshall's article; see note 1. 4 Lindbeck also seems to make it a necessary condition of " ontological truth" that the utterance be performative in J. L. Austin's sense. The Nature of Doctrine, p. 68 et pass. Since Marshall does not dwell on this in his article, I only note it here. For a brief but incisive criticism of this condition, see Paul Griffiths, "An Apology for Apologetics," Faith and Philosophy 5 (Oct. 1988) : 409-11. It may be that Lindbeck was led to stress utterances as the locus of truth, curious though that seems, because the alternative is to make what is uttered true, and that would be independent of the person's practice in a way that utterance seems not to be. AQUINAS AS POSTLIBERAL THEOLOGIAN 483 must also be consistent or cohere with the paradigmatic propositions of the religion, with its revealed...
