If you believe in God, then you must believe in Satan. If you believe in angels, then you must believe in demons. If you believe in good, by balance there must also be bad...Since the beginning of history, humans have suffered demonic possession. The Catholic Church first published the Rites Of Exorcism in 1614. Exorcism is a rare and secretive procedure. The subject must undergo a thorough medical examination prior to being formally acknowledged by the Church as Demonic possession, and the Diocesan Bishop must give priests (who train in Rome) special permission to perform the procedure on each case.This book contains the latest version of this fascinating ritual, amended in 1999.
