I Need first of all to explain my title. The images which I want to think about are primarily images in the mind rather than actual pictures, statues, or such like; or rather I want to think about actual pictures from the point of view of the image which they evoke, and leave behind in the memory, which may live and grow there, and become part—a vital part—of that stock of symbols which in some sense or other exists in all our minds. Because it is in this way that images are part of the life of the Spirit. Or to put it in another way, the activity of the imagination is or should be part of religion—like every other human activity—and needs therefore to be trained and fed. The Church has, we all know, always believed in images; but it is so often thought today that the nature of the image does not matter, provided that it promotes devotion.
