They did it at a RC church?Yes, probably because of the anticipated number of attendees.
Interesting. I always thought the OO's were so strict on that kind of stuff. It's interesting for me to see them make the same concessions many EO hierarchs make. I definitely understand the point of it, I just never thought the OO's would go that route.
As our numbers grew, it seems the Coptic bishop finds no problem using non-Orthodox churches. But I don't think he necessarily prayed with the Catholics. It was it seems strictly an OO-lead event.
Plus, not all OO is strict. The strictest OO churches are Copts, Ethiopians, and Eritrians.
