Answer:
The council of Trent was held over a period of 18 years and was in charge of the Pope, about twenty-five bishops and five superiors of religious orders. In this council, which culminated under the mandate of Pope Pius IV, it was decided that the bishops should present impeccable ethical capacity and conditions, ordered to create specialized seminars for the formation of priests and confirmed the requirement of clerical celibacy. The bishops could not accumulate benefits and should reside in their diocese.
