Only in modern times, some Eastern Orthodox Churches have revived the ancient practice by creating internal ecclesiastical provinces on the middle (regional) level of church administration. In the Romanian Orthodox Church there are six regional metropolitanates, headed by local metropolitans who preside over regional synods of local bishops, and have special duties and privileges. For example, the Metropolitan of Oltenia has regional jurisdiction over four local dioceses. On the other hand, a majority of Eastern Orthodox Churches remain and function as highly centralized church bodies, each of them functioning as a single ecclesiastical province.
