EUCHOLOGIUM, ευχαλογιον, a Greek term, signifying literally a discourse on prayer. The word is formed from ευχη, prayer, and λογος, discourse. The euchologium is properly the Greek ritual, in which are prescribed the
order and manner of every thing relating to the order and administration of their ceremonies, sacraments, ordinances, and the like. Gore has given an edition of the Greek euchologium in Greek and Latin, with notes.
