 Yet Arnauld also assumed that the man’s decision, like any meritorious act of will, was free. Arnauld’s basic position on the compatibility of the intrinsic efficacy of grace with the freedom of the volitions produced by the grace, is that we know from Scripture and Tradition, supported by philosophical reflection on God’s omnipotence (a) that the grace of Christ is intrinsically efficacious; and we know “from our own experience” (b) that our volitions of the relevant kind are free. Hence we know that (a) and (b) are consistent, even though we have “great difficulty” in seeing how they fit together (OA, 10:436).
