It continued to have its own culture and people, who spoke varieties of Aramaic, and
who continued to refer to their homeland as Babylon. Some examples of their cultural products are often found in the Babylonian Talmud, the Gnostic Mandaean religion, Eastern Rite Christianity and the religion of the prophet Mani.
Christianity came to Mesopotamia in the 1st and 2nd centuries AD, and Babylon was the seat of a Bishop of the Church of the East until well after the Arab/Islamic conquest. Why does it seem EVERYTHING has to be argued about here? Can nothing a non-catholic says be accepted???
