At first sight the word 'liberalism' does not seem threatening in any way. Quite the reverse, it is often associated with ideas like 'democracy', 'freedom' and 'generosity of spirit'. However, there is something quite sinister about 'theological liberalism'; although not a well-defined term, it usually refers to a belief system which rejects the orthodox view of the Christian faith as set out in the Bible, and summarized in the church's historic creeds and confessions. This book traces the origin and development of theological liberalism and convincingly demonstrates what a dangerous and destructive thing it is to the Christian church. The author shows that a battle continues to rage today, not between two varieties of true Christianity, but between truth and error, light and darkness, good and evil.
