Carolyn Osiek and David L. Balch tell us in "Families in the New Testament World - Households and House Churches" that while the attendants stand ready for their ministry and there is silence, the president gives an exposition of Holy Scriptures, and then rises and sings a hymn to God, a new or an old one. All the others make their turn, listening in silence except for the closing refrains, when all, men and women, lift their voices.
After the hymns, the young men bring in portable tables with bread, salt and water, although some will laugh, there is neither wine nor meat. While most eat leavened bread seasoned with salt mixed with hyssop, the simplest and purest food is reserved for their superiors, unleavened bread with salt unmixed. After supper there is an all night vigil. What elements of this New Testament worship have come down to us today?
