 Aquinas’s model of faith, though widely thought of as conforming to an evidential requirement on belief, may arguably be open to interpretation as a doxastic venture model. As noted in Section 5, Aquinas holds that the available evidence, though it supports the truth of foundational faith-propositions, does not provide what Aquinas counts as sufficient (i.e., demonstrative) support to justify inner assent (in addition to references to the Summa Theologiae given previously, see 2a2ae. 2, 1 (Aquinas [2006], 63); and compare also Penelhum 1989, 120). Now, whether practical commitment to the truth of a given faith-proposition does or does not venture beyond adequate evidential support will be relative to assumptions about (a) where the level of evidential support required for ‘adequacy’ should be set, and (b) just how firm and decisive propositional faith-commitment needs to be. On some such assumptions, for example those made by Bayesians, the support provided by the evidence Aquinas adduces—or, by a suitable contemporary upgrading of that evidence such as that provided in the works of Richard Swinburne—may be considered enough to make reasonable a sufficiently high degree of belief (or credence) in the truth of theistic faith-propositions so that believers need not venture beyond the support of their evidence. Interpreting Aquinas’s model of faith as conforming to evidentialism may thus be viable. Nevertheless, Aquinas’s own assumptions on these matters may leave him closer to Kierkegaard and Tillich than is commonly thought (consider Summa Theologiae 2a2ae 4, 1 and, once again, 2a2ae 6, 1 (Aquinas [2006], 117–9 &amp; 167)).
