See St. Chrys. on Coloss. Hom. III. (as quoted by Mr. Field). “When the bishop enters the church, immediately he says, ‘Peace be to all;’ when he exhorts, ‘Peace to all;’ when he consecrates, ‘Peace to all,’ when he enjoins the salutation, ‘Peace to all;’ when the sacrifice is ended, ‘Peace to all;’ and at intervals again, ‘Grace to you and Peace.’”
