ROME (AP) — Pope Leo XIV affirmed Wednesday that priests must be celibate and insisted that bishops take “firm and decisive” action to deal with sex abusers, as he gave marching orders Wednesday to the world’s Catholic hierarchs. Leo met in St. Peter’s Basilica with about 400 bishops and cardinals from 38 countries attending this week’s special Holy Year celebrations for clergy. History’s first American pope reaffirmed Wednesday that the primary role of bishops is to forge unity in his diocese among clergy and to be close to his flock in word and deed. Bishops must live in poverty and simplicity, generously opening their homes to all and acting as a father figure and brother to his priests, Leo said. But he refused appeals from Amazonian bishops to allow married priests to address the priest shortage in the region.
