the Dura church was about 1m square and 1m deep; baptismal candidates could stand in it, but could not be immersed. In the new cathedrals, as had been the case before, only bishops baptised; and ceremonies were held not more than twice a year to allow for suitable periods of instruction. So baptisteries needed to be greatly increased in size, with associated accommodation to ensure privacy in undressing, anointing and redressing; and the baptismal tank, commonly octagonal, was now fully deep enough for total immersion, and wide enough to accommodate both the candidate and an assisting male or female deacon. Baptisteries commonly adopted centralised plan forms derived from funerary chapels; and are invariably separate from the congregational basilica. Episcopium No one lived in the house church at Dura; such residential facilities as the latrine and kitchen were removed in the conversion. But cathedral complexes always included an episcopal residence. Prominent amongst the charges that had been directed against Paul of Samosata had been his alleged over-familiarity with pious women. As was common, Paul had been married when elected bishop; and again, as was universally expected for a bishop, he had then ceased sexual contact with his wife and no longer cohabited with her. But his accusers charged that, by continuing to associate with other women (even without any indication of actual impropriety) he was creating an unacceptable potential for scandal. To avoid similar such occasions arising, it was necessary for the new cathedrals to create male-only living quarters for the bishop and his entire establishment; and since, in churches in the West, all presbyters and deacons were also expected to live apart from their wives after ordination, these living quarters, the episcopium, were necessarily substantial in extent. In addition to eating and sleeping quarters for ordained boys and men, the episcopium also commonly provided private dining halls for the hospitality expected of the bishop's enhanced social status, a private oratory or chapel for the bishop, and often a bath house. Finances Just as the episcopal residence was integral within the complex of cathedral buildings, so too there was no distinction between episcopal, diocesan and cathedral property and endowments. In principle, all diocesan income was paid into a common fund, and divided into four fixed shares for each main area of expenditure; the Bishop himself; the cathedral clergy; the fabric and lighting of cathedral and city churches; and charitable donations.
