Now faith is the assurance of things hoped for, the conviction of things not seen. For by it the people of old received their commendation. By faith we understand that the universe was created by the word of God, so that what is seen was not made out of things that are visible. -Hebrews 11:1-3
For John Calvin biblical faith functions as knowledge of God. He develops this locus in his so-called duplex cognitio Dei (two-fold knowledge of God). Karl Barth and Thomas
Torrance follow this notion of faith, respectively, in what can be called an analogia fidei, or analogy of faith. For Barth and Torrance this signifies the relationship that obtains between God and humanity in Jesus Christ. Christ comes, and by His Spirit anointed faith, He presents the only accurate way for a person to have knowledge of God. For Barth and Torrance, respectively, this is grounded in the bond of trust that the Son has always already had in the Father, and the trust that the Father has had in the Son by the Spirit. It is in this relationis (relation) of faith that as the person comes to participate in the life of God through the vicarious humanity of Jesus Christ, that a person finally and truly comes to have a genuine knowledge of God. The key here is that this knowledge is the real deal, and not contingent upon anything or anyone else other than God. In this frame God reveals God, and that is the end of it.
John Webster, while not necessarily providing a full-throated explication of Calvin’s, Barth’s, or Torrance’s notion of faith, presents a development of faith that is in keeping with what we have been sketching thusly. He writes:
There’s no immediate vision; there’s no point, not even in faith itself, at which the barrier between us and God is dismantled and we are face to face with God. What there is now—all there is now—is hope, not sight.
Because of this, faith is contested. It’s contested by those who don’t share our faith, and we ourselves contest it. We often feel dismayed by the fact that what we have believed in is so frustratingly intangible, invisible, apparently so far out of our reach. So often it seems as if faith is hanging in mid-air, insecure, ungrounded, utterly perilous and exposed. Now, because faith it seems suspended in nothingness, we often try to replace it with something else. We look for tangible reassurances. Rather than hope, we want possession; rather than things glimpsed in the half-light of faith (1 Corinthians 13:12), we want something we can see clearly and unambiguously. And so we build up a great array of tangible substitutes for the God whom we encounter in faith. Sometimes we place a great deal of weight on arguments and ideas, looking to them to provide some sort of reliable, uncontested ground for faith. At other times, we look to experience of God; very often we’re tempted to think that experience will give us a sort of direct route to God which will shortcut all the ambiguities and hesitations of the life of faith.
Of course arguments and experiences have their place, but they are not gods. They may not substitute for the God who is known in faith. And the trouble with these tangible reassurances is that they threaten to do just that: They are a flight from faith. They seem, of course, to be quite the opposite—a way of confirming faith, a way of proving to ourselves that what we trust in faith really is real and trustworthy. But in fact they’re a spurning of God; they’re a refusal to have God on God’s terms. They turn their backs on the way in which God encounters us and instead look for something different, something better, something without the apparent fragility and vulnerability of faith. They don’t want to see something from afar; they want to see it clearly, here and now. They don’t want to live in the land of promise; they want to arrive, to be in the city.
To want those things is enmity with God. It’s to want God on our terms, and therefore not to want God. Or, we might say, it’s to want a different god from the God who really encounters us. It’s to replace God with an idol, and so to commit the great sin of religion. Religion is sin when it makes God into something which we can handle. Whether we handle God through graven images or theological ideas or liturgy and music or ecstatic experience doesn’t really matter. It’s all idolatry, all a flight from the city which God builds, all a way of saying that God as God isn’t good enough, and that if God is to be worth trusting he’ll have to conform to our expectations and needs. None of us is exempt; all of us have to realize that religion always carries with it the danger that we will make God into the likeness of something on earth, and in doing so we will lose faith, and lose God.1
Webster assumes on the faith as knowledge of God tradition, and applies that in a certain significant direction. Some might say this sounds like fideism (V so-called evidentialism), but that would miss precisely the point that Webster is pressing. Webster premises that the concrete ground of faith is extra nos (outside of us), and of course the ground is God Himself. As is clear from Webster, faith, genuinely Christian faith, is of the sort that is not self-generated or self-sustained; indeed, for the Christian, faith, according to Webster, is a reality that comes to us in the presence of Christ. This makes faith, as he emphasizes, both vulnerable and fragile; a reality that we cannot possess, but that possesses us instead. As Webster rightly notes, it is just at the point that we attempt to rip faith asunder from the heavens and take it for ourselves that we, like Micah, make an idol out of a reality that does not rightly belong to us (cf. Judges 17.1-6).
I think that what Webster is describing finds its best fund as we ground knowledge of God in the vicarious faith of Christ for us. It is only at this point that a notion of faith ceases from being an abstract floaty thing up yonder, and becomes grounded in the dusty flesh and deep red blood of Jesus Christ. When we come to realize, as the Apostle Paul did, that Jesus is the genuine ‘Mediator between God and humanity,’ it is just at this point that we will come to have a right understanding of faith’s concreteness; a concreteness not of our own assertion.
