The decline of Christianity worldwide is no secret and it may be expected that churches will die, or--at most--become fringe phenomena. As science progresses it gets clear that the Bible cannot be regarded as divinely inspired due to all the mistakes, contradictions, fiction dressed up as history and inhumane laws it contains. Christian doctrines are often irrational superstitions, and one may lead a happy, meaningful and moral life without being religious. This book is a must-read for theologians, philosophers and scientists, but it is also aimed at the lay person who is interested in religion, philosophy, and science.
