Because we are convinced that God’s Word is trustworthy and that that conviction is a reasonable conviction, we can trust God’s Word even for those things that we cannot see. John Calvin also argued the point that true faith is not believing against evidence. Rather, true faith involves trusting in the evidence that God has amply provided in and through His Word. That faith is not without what Calvin called evidences; rather, it is a faith that surrenders to or acquiesces to the evidences.

In this postmodern culture we have witnessed a fascinating revival of ancient Gnosticism. The Gnostics of antiquity were called by that name because they asserted that they had a superior type of knowledge that surpassed the insights found even in the apostles of the New Testament. They maintained that the insights of the apostles were limited by the natural limitations suffered by human beings tied to rationality. True knowledge, according to these heretics, was found not through reason or sense perception, but through a highly developed mystical intuition. In like manner, in this postmodern world we’ve seen a wide spread rejection of rationality. This rejection of rationality has infiltrated the church with a vengeance. We see frequent attempts to remove the Christian faith from all considerations of rationality. It is being argued today that biblical revelation is only intelligible by intuition or by a particularly sensitive poetic imagination. This carries with it the idea that biblical revelation is unintelligible through reason.

For good cause, the church in recent centuries has had to reject rationalism in its many faceted forms. There is no monolithic philosophy of rationalism; rather, rationalism wears various faces. On the one hand, we think of rationalism as distinct from empiricism with respect to how we come to know what we know. Second, Enlightenment rationalism contrasts reason not with sense perception but with revelation, arguing that revelation is unreasonable and the only truth that can be known is that which can be known by natural reason. The third and most complex form of rationalism is Hegelian rationalism, which defines reason with a capital R, and reality is the unfolding in space and time of ultimate reason. None of these philosophies represents historic Christianity. Christianity is not based on rationalism. However, the rejection of rationalism in the modern church often carries with it the rejection of rationality. This rejection is itself irrational. When we reject humanism, we don’t reject being human. If we reject existentialism, we don’t reject existence. So, if we reject an “ism” attached to reason, it does not mean that we are to reject reason itself.

We must be on our guard and vigilant at every moment against the intrusion of irrationality coming from existential philosophy, neo-orthodox theology, and the resurgence of mysticism set forth in neo-Gnosticism.
