Canon 19 Provincial synods of bishops meet twice a year

It has come to our hearing that in the provinces the synods of bishops prescribed by the canons are not held, and that because of this many ecclesiastical matters that need correction are neglected. The holy synod has therefore decreed, according to the canons of the holy Fathers, that the bishops in each province come together to the same place twice a year, wherever the bishop of the metropolis shall approve, and correct each of the matters that arise. And bishops who do not come together, though they are staying in their own cities, and that in good health, and free from all unavoidable and necessary business, are to be rebuked in a brotherly manner.
