Most of the things we assent to, whether a priori or a posteriori, are not volitional. One does not will to believe that God exists any more than one wills to believe the rose is red. These are mental assents that are not discursive; they are immediate and without reflection. The will is bypassed.1 However, the gospel always engages the will as the unbeliever counts the cost and by grace abandons all hope in himself while looking to Christ alone, finding rest in Him. Accordingly, it is inadequate to reduce justifying faith to belief alone when belief is reduced to assent without remainder.
Clarkians and easy-believism advocates promote that we are justified by belief alone. One is justified by assenting to “Jesus died for me.” Another extreme comes from “Lordship Salvation” advocates who define trusting in Christ in terms of commitment of life, which eclipses the gospel and redefines how one might appropriate Christ as he is freely offered in the gospel. The focus of this post is on the former error.2
Clarkians will assert that assent is synonymous with resting in or relying upon Christ. In this context it is suggested that to assent to Christ dying on the cross for my sins is to “trust” the proposition is true. Albeit the premise is true for true believers, this observation turns on a subtle equivocation over the word trust. Indeed, to trust a proposition is true is no different than to assent to its truth. So, in that sense trust and assent are synonyms. However, to trust that something is true is not the same thing as to trust in something because it is believed to be true. The latter idea of trust carries the meaning of reliance upon, whereas the former use of trust merely conveys an intellectual assent that might or might not be accompanied by reliance. Accordingly, to argue that trust and assent are synonyms in this way is to deny implicitly the need to trust willfully upon Christ alone for salvation.
Clarkians redefine trust so that they might appear confessional since the Westminster standards clearly speak of not just “accepting“ the gospel as true but also relying upon (i.e. trusting in) the finished work of Christ. (It’s not just equivocal but also a downright case of special pleading to define “trust” as a synonym for assent and then on top of that limit its use to assent. Clarkians should out rightly deny trust rather than suggest they affirm it. The trust they equate with assent is not the trust of the Reformed tradition for that trust is metaphysical and volitional. It does not mean assent. It presupposes it!)
Assent pertains to accepting something as true, even possibly with no reflection, whereas trust (or lack of trust) pertains to the degree of relevance a person might assign to the “assented to” proposition. Assent is a mental act that need not be accompanied by volition; whereas trust in Christ is always volitional in nature. Assent always pertains to accepting the truth of a proposition, whereas how one might respond in light of assent (e.g. trust, rest, exuberance, etc.) is commonly classified under the philosophical heading of disposition (which is not propositional assent). Whereas trust and other dispositions can evidence assent, dispositions need not accompany any given assent since assents can be mundane, occur without reflection and, also, be subjectively perceived as inconsequential. (This is why philosophers consider disposition to be a poor indicator of the presence of assent. Dispositions are sufficient but not necessary for assent.)
Assents or beliefs are propositional attitudes that can be distinguished from volitional, metaphysical movements. For instance, choices are mental activities that engage both the intellect and the will. This is more recognizable once we consider that choices involve both judgment and reliance. What one deems as true can result in a choice to rely upon that which the judgment contemplates, but the intellection of belief need not give way to volition. This is sufficient to demonstrate that belief and volition are not the same things though they often go together. This observation would seem rather uncontroversial in the Reformed tradition. It was presupposed in Jonathan Edwards’ writings and was taken up by men like R.L. Dabney, A.A. Hodge and even William Cunningham. Yet contra this popular view, Gordon Clark believed that it is an illusion (an illusion, mind you!) to think that such acts of intellection differ from volition. Clark went so far to say that belief in a chair is volitional.
If assent and trust were synonyms, then either both would mean cognitive conviction or else volitional reliance. Conviction of truth (assent) could never give way to reliance upon truth (trust). If assent and trust are indistinguishable concepts and, therefore, mean the same thing, then it would be unintelligible to say that we rely upon anything we believe; nor would it be sensible to think that we believe anything we rely upon. Intellectual assent without reliance leaves no room for relying upon Christ; whereas reliance without conviction paves the way to trusting in Christ while not assenting to the gospel. Obviously, the concepts are indeed distinguishable as well as distinct principal acts of saving faith.
1 Even when the will is engaged in choosing, we don’t will belief. Doxastic Voluntarism is a philosophical surd.
2 In the not so distant future I plan to address the gospel according to John MacArthur and the nature of faith as the instrumental cause of justification. MacArthur fails to distinguish and ends up conflating the disposition of reliance upon Christ with the sanctifying grace that inevitably produces a faithful commitment of life to Christ.
