“ In a cathedral of the Church of England “lay clerks” and “lay vicars” sing such portions of the service as may be performed by laymen and clergy in minor orders. “Lay readers” are persons who are granted a commission by the bishop to perform certain religious duties in a particular parish. The commission remains in force until it is revoked by the bishop or his successors, or till there is a new incumbent in the parish, when it has to be renewed. ”
