Aquinas as Postliberal Theologian

AQUINAS AS POSTLIBERAL THEOWGIAN BRUCE D. MARSHALL St. Olaf Oollege Northfield, Minnesota, 1JHE PURPOSE of this essay is to discuss the relation between Thomas Aquinas' account of religious and heological truth and a " posrtliberal " one sruch rus that sketched in George Lindbeck's The Nature of Doctrine. Most reviewers assume that Lindbeck's .app:voach is on this point incompatible with the mainstream of the tmdition, and Colman O'Neill, writing :in The Thomist symposium on Lindbeck's book, thinks it oontradicts Aquinas in particular. This paper presents the case to the contr:ary. Afte'I." outlining O'Neill's problem, it argues thart he mis11eads Lindbeck 'and, .at greater length, that Aquinas''S views on t:ruth :are, as Lindbeck affirms, compatible with postliberal emphases. I O'Neill's basic problem with Lindbeck's: "cultural linguistic " understanding of truth is thwt Lindbeck " would clearly have us puTify [Christi.an] language by ridding it of extra-linguistic accretions-in particular the intrusion of reference to objective reality. In the end the only thing that matters is scriptural discourse verified by action." 1 Lindbeck may not intend this " purification," 2 but whatever the intention, his 1 Colman E. O'Neill, "The Rule Theory of Doctrine and Propositional Truth," The Thomist 49 (1985), p. 422. 2 So Lindbeck writes: "The great strength of a cognitive-propositional theory of religion is that •.. it admits the possibility of [ontological] truth claims, and a crucial theological challenge to a cultural-linguistic approach is whether it also can do so." The Nature of Doctrine: Religion a,nd Theology in a, Postlibera,l Age (hereafter ND), (Philadelphia, 1984), pp. 63-4. 353 854 BRUCE D. MARSHALL view of •religious truth entails a raidical rejection of 1any claim that Christian beliefs !are onto1ogioally true, in other words, tha;t they rre£er or correspond •to reality. The reruson rllor this putative entailment lies in Lindbeck's manifest oontention (to be explained below) that truth claims in any l'eligion, including Christianity, are subject to 1a twofold criterion of coherence: they must fit wirth the wider linguistic (especially scriptural) paradigms of the 11eligion, and also with a range of practices appropriate to the belief the truth of which is being claimed. But, says O'Neill, Christian beliefs are not true because they cohere with anything, they are true (like all true propositions) "because of their reference to the real." a By introducing ;an irreducible element of coherence into his interpl'etation of Christian truth claims, Lindbeck inevitably " attaches to the ·term ' propositional truth ' .a purely pra.gmatic signification," so that " a quite precise philosophical option has: been ma.de in faV'or of the moral or pragmatic definition of truth." 4 O'NeiiH'is point is that " ontological " or " propositional " truth has here been equa,ted with nothing more than the con£ormity of one's life to the patterns narrated in the !biblical story (O'Nei1l's "·scriptural dis-·oourse verified by 1action ") , •such tha;t " no claims to objective truth" need be made for the story or any a.ssociated beliefs.5 Tihis, O'Neill alleges, is ·a " novel definition of ontological truth." 6 We ought to !'eject this novelty in favor of the under- •standing of Christian beliefs and their truth articulated by 'Ihomas Aquinas, whel"e it is firmly maintained against " the moral or pmgmatic definition of truth " that " propositions are true because of their I"eference ·to .the real." In order to undevstand the issues ·raised by O'Neill's criticism , it is important to bear in mind the distinction-often made but often overlooked ais well-between truth :and justis O'Neill, "Propositional Truth," p. 430. 4 O'Neill, "Propositional Truth," p. 429. 5 O'Neill," Propositional Truth," p. 420. 6 O'Neill, "Propositional Truth," p. 431.

The very isisue of what it means to say that propositions 1 are true can be distinguished from the issue of ho,w one justifies, warrants, or tests the truth of propositions. So, for example, one might maintain that in regard to propositions, "true" should be defined as "oorresponds to reality," or perhaps "fitly expresses experience," or perhaps "is...
