The Daytona Beach Drive-In Christian Church has been offering worshippers in Florida Sunday services in the convenience of their cars for more than 60 years. Operating much like a drive-in movie theatre, the congregation parks and tunes in on the radio for Bible readings and sermons from the presiding minister in the altar building. Even pre-packaged consecrated wine and communion wafers are provided. Respectfully filmed yet imbued with dry humour, the US director Lauren DeFilippo’s observational short documentary Clean Hands guides us through a regular Sunday service here, prompting the viewer to ask: does Christian communion lose its meaning when shared from the comfort of a parked car?
