Deschner anticipates the main criticism at his work, namely the one-sidedness of selection of facts, and responds with a clear counter. His aim was not a history of churches, but an illustration of all (including non-church) phenomena of Christianity. These would be measured up to not only generic terms, like crime or humanity, but also to the central ethical ideas of the synoptics, as well as to the Christian self-conception as the religion of glad tidings, love, peace, etc., and also the ignored demands of the later church, like prohibition of military service (first for all Christians, then for the clergy, only), ban on simony, interest-taking, usury and many more.
