Originally published in 1948, Christianity and Fear explores the nature and history of Christian love in relation to the problem of fear.

Based on methods of depth psychology and mental hygiene, the book argues for the necessity of a general concentration of the Christian religion and way of life upon the unity of love through faith and faith through love. It presents the struggle between the teaching of Christian love and the many instances of disputes on dogma that have prompted hatred and fear throughout ecclesiastical history. By using the theory of fear and compulsions, it attempts to explain the directions assumed by these aberrations in Christian history and to highlight love as the essence of the teaching of Jesus.

Christianity and Fear will appeal to those with an interest in the history of Christianity, theology, and the psychology of religion.
