Dulia
A term used in medieval theology to distinguish the reverence which may legitimately be paid to the saints from the worship (latria) which is paid only to God. Since both words can be translated as worship in English and most other languages, the distinction was important in the controversies concerning the veneration of saints, icons, and things other than God. See Latria.
