Faith, in the Christian life, has nothing to do with a subjective belief that does not admit rational justification (not even Kierkegaard quite said that), because faith begins not with the subject of faith but its object””the Trinitarian life of God. It consists not of assent to some proposition but the entrustment of one’s being to God’s providence. Faith does not originate in the individual believer’s own efforts, but is rather a gift of grace to the believer, usually received in baptism, as one means among many of participating in God’s own life.
Far from posing a threat to one’s faith, knowledge reinforces it: the more reason one has to believe in God’s providence, the more readily the believer entrusts himself to God. Faith likewise facilitates a more intimate knowledge of the plans God has set in store for the believer. As recent scholarship has demonstrated, “faith” in the Bible is often better rendered “faithfulness”; one has faith, therefore, less by belief than by piety. Faith is””at least in the order of time””primarily performative and only secondarily reflective. Recall St. Irenaeus’ dictum: “to believe in God is to do his will.”
The naive concept of faith as blind assent arose from an equally naive and philosophically disreputable theory of knowledge, according to which one knows a thing best by detaching oneself from its use and setting aside personal biases in order to form an idea that corresponds to the thing.
