What was the very first church in Egypt?

The house of Annianus, the first man who accepted the faith at the hands of St. Mark in Alexandria, became the first church in Egypt. Afterwards they were able to build a considerable church in the suburban district of Baucalis.¹¹⁹² On the eve of the Resurrection Feast of 68 A. D., the pagans were greatly agitated to find that their great Temple of Serapis was deserted while the church at Baucalis was actively crowded, so they rushed into the church and seized St. Mark to kill him.
