The present book was written to reassure ordinary believers that the faith they received as children is still true, whatever some theologians might say. As Balthasar himself puts it, “the unfortunate thing is that, with their supposed science, the wise and clever, often enough theologians, unsettle the simple. The latter feel in their correct instinct of faith that something is fishy, but they do not find the correct answer. Therefore the people who are unsettled, despite their good instinct, need to have a short primer placed in their hands so that they may find for their inner vision of Christian truth at least an outline of a few written signs which they can show to their tempters. . . . This little book addresses unsettled laymen. Is it too audacious to hope that some of those who have done the unsettling will also pick it up and let themselves be unsettled here and there in their settled self-confidence?” (From the author’s Preface).
