Ceremony

CEREMONY. Ceremonia  in its classical sense was a general term for worship. Johnson defines a ceremony to be "outward rite, external form in religion." Hooker uses the word in this sense. In a larger sense it may mean a whole office. All should read that part of the introduction to our Prayer Book which treats "Of Ceremonies, why some are to be abolished, and some retained" (written in 1549). see  also Art. xxxiv.
