Another volume in the new Layman's Theological Library series, of which Robert McAfee Brown is editor. In his introduction, he reminds the reader that the injunction to love God, ""with all thy mind"" necessarily involves the layman in theology. If he refuses to think through his faith, he simply settles for an inferior theology. The ""Library"" will attempt a fresh exploration of the Christian faith and what it can mean to contemporary man. In this volume, Dr. Loew examines various rivals to the Christian faith, and indicates many of the ingredients which must replace these rivals. The chief ones are science, democracy and nationalism. He reveals their weaknesses and dangers when they become idols in the minds and hearts of men. The rivals exist not only outside the Christian faith, but even more dangerously with Christian faith. He examines carefully the so-called return to religion, and gives special attention to the ""peace of mind"" and ""positive thinking"" cults, which he says ""puts man in the driver's seat, rather than God, and results in either sanctioning our secret ideals, or clothing them with tattered remnants of Christian faith"". This trenchant book seeks to remove excesses and current distortions of the Christian faith. This it does with a vigorous forthright style which recommends itself to a wide reading.
