A nun was crucified by a priest and four other nuns during an exorcism ritual. She was rescued but later died from an adrenaline overdose. The five killers thought the nun was possessed of the devil so they chained her to a cross, gagged and deprived her of food and water for several days at the remote monastery in June. Authorities had maintained the treatment proved fatal and she was already dead when other nuns called for an ambulance.
I don’t recall where crucifixion is suggested as an effective treatment for demon possession. Know your bibles. Your life depends on it, in many ways.
