Anyone have any information on bishop Damasus?

I found out about him being the first guy who claimed that the church of Rome was in charge of all other churches. I would like to find out about him and some of the bishops of other cities that he had excommunicated. John

Hi JohnThis might be a starting point. Damasus.

Hey, thanks Philologos! Finally someone answered it. It did provide just a little more light on the founding of Roman Catholicism.John
