As pope, Stephen enforced the policies of the Gregorian Reform. He held several synods in Rome from August to November 1057, focusing most vigorously on the importance of clerical celibacy. He held a synod at the Lateran Basilica in which he remarked that the Eastern Church tradition allowed priests, deacons, and subdeacons to marry, but the Western Church did not.
