Why does today's Christian find the reading of great books always beyond him? Certainly intellectual powers do not wane from one generation to another. We are as smart as our fathers, and any thought they could entertain we can entertain if we are sufficiently interested to make the effort. The major cause of the decline in the quality of current Christian literature is not intellectual but spiritual. To enjoy a great religious book requires a degree of consecration to God and detachment from the world that few modern Christians have. The early Christian Fathers, the Mystics, the Puritans, are not hard to understand, but they inhabit the highlands where the air is crisp and rarefied, and none but the God-enamored can come.
