Mass

A term for the Holy Eucharist. It is primarily used by Anglicans, Roman Catholics, and Lutherans. It appeared as a part of the title of the service in the first BCP of 1549. It is included by the Catechism in a list of names by which the eucharist is known (BCP, p. 859). It is derived from the Latin missa, which is from mittere, "to send." It was a part of the dismissal in the medieval Latin Mass, Ite, missa est ("Go, it is finished").
