We just watched the movie, Exorcism of Emily Rose.
The movie may depart from actual events. Who knows? But Mary appears at the end. My wife is sure God could have used her for that event.
Does the exorcism by a Catholic Priest validate the doctrines and teachings of the Catholic Church? They did pray the Rosary in the exorcism as I think Catholics would. Is God wrestling with the decision of who He will help?
Does it fit the Scripture of those who preached from wrong motives but found their preaching still productive?
