St. Benny the Dip is a 1951 American comedy film directed by Edgar G. Ulmer.
Benny, Monk, and Matthew are three small-time crooks trying to escape a police dragnet in New York City.
After hiding in a church and taking minister's suits and dog collars, they emerge, dressed as priests, and find shelter in an abandoned Bowery mission.
When beat cops mistake them for real ministers sent to restore the soup kitchen, they are forced to go along with repairs, holding services and feeding the poor.
As with Jean Valjean in Les Misérables, when the bishop he has robbed lets him go, it is the first time they have been treated with respect and had a chance to do good work.
