Theologian Kurt Koch spent much of his life researching the occult and ministering to those affected by it. In Occult ABC he combines those years of work into an informative guide to the practices and ideas that form the foundation of the occult. If you learn its language, its alphabet, you can better combat it. That is the spirit that Occult ABC is written in.
Though some may not agree that all of the practices mentioned in here are occult (charismatic occurences and Pentecostalism come to mind), most will agree that Koch has provided useful information on what is going on in the occult. Each topic includes a brief introductory description, as well as examples from Koch's life and research. Alphabetically arranged, with extensive footnotes, this is a valuable resource for those who have dealt with, are dealing with, or will deal with the occult.
