The wide range of forbidden trades specified (as for example, charioteers), confirm a place of composition in one of the two major urban centres of the Roman Empire, Rome itself, or Alexandria. Particular provisions in the Church Order relate to local practices which identify this place as Rome; specifically that the dead are buried in catacombs sealed into shelves with tiles; and also the stipulation that, in the regular Sunday eucharist, portions of the bread consecrated by the bishop are to be broken off by deacons and carried by them to presbyters in other churches in the city, wrapped in napkins.
