Organizers of the Paris Olympics are apologizing after some viewers of the games’ opening ceremony were offended by a performance of Leonardo da Vinci’s “The Last Supper.”

The French performance of da Vinci’s “The Last Supper” featured DJ and producer Barbara Butch as well as drag artists and other dancers. Some religious officials were offended by the display, with the French Catholic Church’s conference of bishops saying the performance “mocked” Christianity.

Olympic organizers issued an apology on Sunday, with the opening ceremony’s artistic director, Thomas Jolly, saying the performance was meant to pay tribute to French feasting and art and to celebrate diversity.
