Azymites, the name given to a party in the Church who insisted that only unleavened bread should be used in the Eucharist, and the controversy hinged on the question whether the Lord's Supper was instituted before the Passover season was finished, or after, as in the former case the bread must have been unleavened, and in the latter leavened.
