Beadle
Beadle, sometimes spelled "bedel," is a lay official of a church or synagogue who may usher, keep order, make reports, and assist in religious functions; or a minor official who carries out various civil, educational, or ceremonial duties.
The term has pre-Conquest origins in Old English, deriving from the Old English bydel ("herald, messenger from an authority, preacher"), itself deriving from beodan ("to proclaim", which has a modern descendant in the English verb bid). In Old English it was a title given to an Anglo-Saxon officer who summoned householders to council.
