The Canons of the Synods of Sardica, Carthage, Constantinople, and Carthage Under St. Cyprian, Which Canons Were Received by the Council in Trullo and Ratified by II. Nice 118Canon XCV.

An universal council to be held only when necessary.

It seemed good that there should be no more the yearly necessity of fatiguing the brethren; but as often as common cause, that is of the whole of Africa, demands, that letters shall be given on every side to that see in this matter, that a synod should be gathered in that province, where the desirability of it induces; but let the causes which are not of general interest be judged in their own provinces.
