Although the church is the proper place for a celebration, yet, in cases of necessity, the holy communion was administered, in ancient times, in crypts, at the tombs of martyrs, in a prison, on the celebrant's breast, in the deacon's hands, in a tent, a hut, a house, in the fields, at sea, by a bedside- anywhere, except in the burial-places of the heathen.
