Canon 11
That every presbyter, father (abba), or deacon shall express humility and greatest reverence toward his bishop.
The gathering of this council has learnt that presbyters, fathers (abbates) and deacons are disobedient to their bishops, and it has been introduced that when presbyters or abbots have exemptions granted by bishops for their churches, then they show proper obedience and just reverence to their bishops, but if bishops have, according to the canons, the right to visit the parishes, then they are insulted and calumniated. Therefore, it pleased the holy council that the presbyters, as well as fathers (abbates) and also deacons be respectful to the bishops. They [the bishops] shall not suffer any contumely, and whenever they visit their dioceses, according to the canonical law, [presbyters, fathers, and deacons] will welcome them duly, and will prepare for them all that is necessary, according to what they have and what is reasonable. We also decree that it shall be observed in every respect that no presbyter or deacon be allowed to attend secular affairs or exercise public duties. If someone wants to transgress the orders of this canon, let him be punished by the sentence of excommunication.
