liturgical language

A sacred language, or liturgical language, is a language, frequently a dead language, that is cultivated for religious reasons by people who speak another language in their daily life.The traditions involved in religious ritual and liturgy quite frequently provide a place where archaic forms of language occur. One of the last places the obsolescent English pronoun thou remains in frequent use is in religious liturgy; wherever the Authorised Version of the Bible is read, or older versions of the Anglican Book of Common Prayer are in use.
