Bishop Of Two Churches

Letter 2,37 - to Bishop Benetatus. July 592

"Because therefore the bishop of the Castrum of Cumae has completed the course of his life, know that we have united each church [i.c. of Cumae and Misenum] with the page of this authority here present, and have entrusted it to you, and know that you are the official bishop for both churches.
And whatever you see fit to ordain and settle concerning their patrimony or ordination of clergy or promotion according to the statutes of canon law, you will have a free license with the agreement and permission of our authority as truly their own bishop.
But live where you will find it most suitable and useful, in such a way of course that you look after the other church, from which you are absent in body at the time, with concern and with providential care, so that the holy mysteries are solemnly celebrated there, with the Lord's help."
