Editor's Note: This article has been revised to reflect the following correction, which appears in Friday's print edition: Because of incorrect information supplied, a front-page article Thursday listing the locations of the three Catholic popes during the schism when Pope Gregory XII was forced to resign in 1415 was inaccurate. The three popes at the time were based in Rome; Pisa, Italy; and Avignon, France. Pope Benedict XVI’s announcement this week that he will resign shocked the Roman Catholic Church, but local Catholics expressed optimism that the church will adjust and move in the right direction.
