Obey your bishop! Obey those set over you [Heb 13:17], the teachers of the Church. I remind you, my dear friends, of what I said when I was with you: do not receive any outside or unknown preacher, unless he be sent by your bishop or preaches with the permission of the pope. For how shall they preach unless they are sent [Rom 10:15]?

St. Bernard of Clairvaux
