The old borough of Bab Tuma was developed at the end of the Roman/Byzantine era by the local Eastern Orthodox community. According to the Acts of the Apostles, Saint Paul and Saint Thomas both lived in that neighborhood. Roman Catholic historians also consider Bab Tuma to be the birthplace of several Popes such as John V and Gregory III. Accordingly, there was a community of Jewish Christians who converted to Christianity with the advent of Saint Paul's proselytisation.
