By C.S. Lewis
His epitaph is Athanasius contra mundum, "Athanasius against the world." We are proud that our own country has more than once stood against the world. Athanasius did the same. He stood for the Trinitarian doctrine, "whole and undefiled," when it looked as if all the civilised world was slipping back from Christianity into the religion of Arius—into one of those "sensible" synthetic religions which are so strongly recommended today and which, then as now, included among their devotees many highly cultivated clergymen. It is his glory that he did not move with the times; it is his reward that he now remains when those times, as all times do, have moved away.
When I first opened his De Incarnatione I soon discovered by a very simple test that I was reading a masterpiece. I knew very little Christian Greek except that of the New Testament and I had expected difficulties. To my astonishment I found it almost as easy as Xenophon; and only a master mind could, in the fourth century, have written so deeply on such a subject with such classical simplicity. Every page I read confirmed this impression. His approach to the Miracles is badly needed today, for it is the final answer to those who object to them as "arbitrary and meaningless violations of the laws of Nature." They are here shown to be rather the re-telling in capital letters of the same message which Nature writes in her crabbed cursive hand; the very operations one would expect of Him who was so full of life that when He wished to die He had to "borrow death from others." The whole book, indeed, is a picture of the Tree of Life—a sappy and golden book, full of buoyancy and confidence. We cannot, I admit, appropriate all its confidence today. We cannot point to the high virtue of Christian living and the gay, almost mocking courage of Christian martyrdom, as a proof of our doctrines with quite that assurance which Athanasius takes as a matter of course. But whoever may be to blame for that it is not Athanasius.
