From Malta-

Pope Francis said late yesterday that he believed that Roman Catholic priests should be celibate but the rule was not an unchangeable dogma, and "the door is always open" to change.

Francis made similar comments when he was archbishop of Buenos Aires but his remarks to reporters on a plane returning from a Middle East trip were the first he has made since becoming pope.
"Celibacy is not a dogma," he said in answer to a question about whether the Catholic Church could some day allow priests to marry as they can in some other Christian Churches.

"It is a rule of life that I appreciate very much and I think it is a gift for the Church but since it is not a dogma, the door is always open," he said.

The Church teaches that a priest should dedicate himself totally to his vocation, essentially taking the Church as his spouse, in order to help fulfil its mission.
