The Sermon on the Mount is not a textbook of morality, a catechism, a book of laws, or a theological treatise. It is a response to the deepest inner yearning of humanity for happiness and bliss. It serves as a guide to inner freedom and spiritual greatness. In expressive sentences and with vivid imagery, it illuminates the true spirit of Christian attitude. Father Richard Gutzwiller has interpreted these principles of the Christian spirit of the Sermon on the Mount in a profound way. He does not get lost in abstract scholarly wisdom, but draws concretely and vividly from life.
