As I began this essay, I expected an eloquent review of the characteristics and origins of Western culture’s current ailments, and I got it. But I got something else too. About two thirds of the way through the book appeared an eloquent description of the Church, a call to arms, and an elaborate battle plan. Perhaps the image that stood out most for me was the analogy of the Church visible—that is, the Church militant—as an outpost behind enemy lines. The “main” Church, or the greater part of the Church, is the Church invisible. Here on earth we’re fighting behind enemy lines and the battles are often waged within the Church itself. But the vast reality of the Church—all the angels, saints, and souls in purgatory—is not visible to earthly eyes. This essay gives us the tools to spot the enemy, ferret him out, and fight the good fight, so that Christ’s victory may take root in as many hearts as possible.
