CCEO does not make a clear division of the powers or offices for the curial bishops. Curial bishops are to exercise the functions entrusted to them by the Major Archbishop. Major Archbishop cannot constitute a vicar for the entire church nor can he delegate his power to someone for all cases. But he can have different vicars for the administration of the Major Archiepiscopal Church, sharing the powers partially, either vicariously or by way of delegation. The curial bishops can discharge functions only within the territorial boundaries of the Church (c. 181 §1).

There can be a maximum of three bishops in the curia in order to help the Major Archbishop. All three bishops would have titular sees and the title of archbishop is given to the senior most bishop of the curia who could eventually be the administrator of the Church. This administrator during the period of vacancy of the See would have the powers of the Major Archbishop. When there are 3 Curial Bishops, there could be three sections functioning in the curia, with curial bishops as heads. All these sections could have a secretary, preferably a priest and if needed other officers.
