The pontiff made the remarks during a Mass honoring Jacques Hamel, an 85-year-old priest murdered by ISIS-supporting teenagers who stormed his church in northern France in July.
"Killing in the name of God is satanic," the pope told the ceremony in the Vatican's Domus Santa Marthae chapel. "I would like it if all religions said this, 'To kill in the name of God is satanic,'" he said.
