When two well-known church critics join forces to write a book about the church, a classic is in the making. This book, which was first published in 1991, achieved overwhelming success. Both Karlheinz Deschner and Horst Herrmann write not only knowledgeably but also passionately and with commitment. They have created a standard work that is now available again in a new edition after a long time, following the death of Karlheinz Deschner. It is a book for anyone who wants to be informed critically and in a well-researched manner about the data, facts, and background of the spiritual business with God and the world.
