Some parishioners arriving at St. Joseph Roman Catholic Church in Fontana were nervous about what the future holds.
"I can't believe what's happened. It's kind of scary, I think," said Susanna Espinoza, an official at St. Joseph.
The concern from Espinoza, a lifelong Catholic, didn't end there. It pondered the future. "What's going to become of our religion?" she said.
Some parishioners hoped that there would be prayers for the Pope's health. Others hadn't even heard the news of the Pope's resignation.
The Rev. Guillermo Martinez heard the news on the Pope from a parishioner after morning Mass.
The Pope's resignation came as a surprise, but he says he's not worried about the future of the church.
"There is no concern because we have good candidates to be the Pope," he said.
