Much has been written about President Joe Biden’s Catholic faith. He often speaks of his religious convictions and quotes the Bible, and he attends Mass regularly.
Although about one-in-five U.S. adults are Catholic and Catholicism has long been one of the nation’s largest religious groups, John F. Kennedy was the only Catholic president until Biden was sworn in. Aside from Biden, only one other Catholic, John Kerry, has been a presidential nominee on a major party ticket since Kennedy’s assassination in 1963.
The U.S. Constitution famously prohibits any religious test or requirement for public office. Still, almost all of the nation’s presidents have been Christians and many have been Episcopalians or Presbyterians, with most of the rest belonging to other prominent Protestant denominations.
