The Man Who Could Work Miracles (1936)

While vigorously asserting the impossibility of miracles, George McWhirter Fotheringay suddenly discovers that he can perform them. After being thrown out of a bar for what is thought to be a trick, he tests his powers and eventually sends a policeman to Hades by accident. Worried, he sends the police officer to San Francisco and seeks advice from the local clergyman, Mr Maydig who, after having Fotheringay's powers demonstrated to him, quickly plans for world reform by means of miracle, but eventually Fotheringay orders a miracle which backfires because of clumsy wording. He relinquishes his power and returns to the time before he had it.
