Another draft clip from the “passion for theology” chapter of my forthcoming Getting Medieval with C. S. Lewis:
So, Lewis sought wisdom through philosophy, and that wisdom led him on a path to Christianity. But he never stopped being a philosopher—even in writing his famous children’s books. One remembers Professor Digory’s exclamation in The Last Battle: “It’s all in Plato, all in Plato: bless me, what do they teach them at these schools!”
For us, on the other hand, the temptation is perhaps the opposite—having found Christianity, we see no use for a reasoned exploration of Truth. What Lewis and the medievals can help us know is that we evangelicals cannot content ourselves with seeking after the charismatic experience of the “beauty of God’s holiness,” or even with the practical pursuit of that holiness in our own hearts and actions. As the classical philosophers taught all subsequent generations, Beauty and Goodness are but two of our proper ends. The third is Truth. For ultimately a beautiful and good life can only remain so if we live it in the light of Truth. And since Christians would agree with all theists that God is the source of Truth, we must turn to God as the first and most proper subject for reasoned inquiry. Which is to say, none of us—even the simplest and most untutored—can abdicate our responsibility (and privilege) as theologians.
For most of us, this will never mean grasping the intricacies of philosophical theology; that is the job of academic theologians, as it is of the pastors they train to grasp at least the bones and sinews of theology (seminaries certainly have as their primary task the training of theologically intelligent pastors). But all Christians are theologians in other ways. First and most simply, as the Orthodox tradition has always insisted, to pray is to do theology. Second, to do theology is also to listen carefully to our pastors and teachers and to read Scripture in the light of the Tradition they pass on to us—for most of us, this is the most important way we do theology.
If we don’t seek and have Truth in our “inmost parts,” then we have confusion, self-contradiction. We have a weak basis for life. And again, in the Western tradition in which most of my readers have been formed, philosophy has always been a way of life. So my argument to modern Christians in this chapter is: blow the dust off the theological tomes. Steal theological pursuits back from the academics, because those pursuits are about life. They are not about making a career or speaking only to others in a technical discipline. As Anselm of Canterbury was, we too must be about “faith seeking understanding.” And we could find much worse guides in that pursuit than such medieval theologians as Anselm, Bernard of Clairvaux, Thomas Aquinas . . . and pointing back to these, C.S. Lewis as the self-styled “dinosaur”—the “native speaker” who translates their medieval ideas for us.
 The early “desert theologian” Evagrius Pontus is said to have put it like this: “He who is a theologian prays truly, and he who prays truly is a theologian.”
 By the way, by distinguishing Truth from Beauty and Goodness, I do not mean to divide what neither medieval thinkers nor Lewis divided. For instance, Lewis begins his famous essay on natural law and virtue ethics, The Abolition of Man, with a challenge against two textbook authors who claim that beauty is only in the eye of the beholder. He insists that on the contrary, beauty is actually present in objects, independent of our perception of them. There is thus, for example, a truth-telling quality of Beauty, so to speak, in a waterfall. And from that truth-telling quality, we can derive (and Lewis does derive, in that essay) the broader principle that there is also moral truth embedded in the nature of things. So here we have Beauty, Truth, and Goodness, all together. To paraphrase Robert Louis Wilken (from his wonderful The Spirit of Early Christian Thought), the great engine driving the search for theological truth, and even perhaps to a degree scientific truth, the early and medieval church history, is not idle or sterile intellectual curiosity, but rather is the desire to know how to live in the light of our Creator God’s love for his creation—the pursuit not only of the true, but also of the good, and indeed the beautiful.
