Sinodos: The Apostolic Canons 25
1It is the duty of the metropolitan bishop to know the bishops of the whole province, and it is their duty to know who is the first among them, and they shall call him the metropolitan. And not shall they undertake an important work without the consent of the leader. And each one shall do his work which is his duty accord- ing to his office and according to the people who are in his diocese. But not even he who has been ordained as metropolitan over them shall undertake anything at all, except with the consent of all the bishops, and thus they all shall be one association and shall praise the Lord through Christ Jesus and the Holy Spirit. And not shall a bishop dare to ordain any one outside of his diocese in localities that do not belong to him. And if he is found as having done this with- out the consent of the head of this place and these villages and cities, let him be deposed together with those whom he ordained.
