In fifteen "irreconcilable essays," Karlheinz Deschner sheds light on episodes from the criminal history of Christianity. First published in 1987, even the contributions that were published on specific occasions, such as the visit of the then Pope to South America, have not lost their relevance. With his characteristic linguistic force, Deschner exposes the Donation of Constantine as a grand fraud, illustrates the difficult relationship between Christianity and sexuality, and criticizes the politics of the popes in the 20th century.
