"bishop's wardens". The only areas in which wardens almost always have no authority, often proscribed by canon, are music and liturgy, which are considered to be under the exclusive authority of the priest or bishop in charge of the parish. Nevertheless, in England churchwardens have authority to officiate at Morning and Evening Prayer if a priest or licensed lay person is unavailable.

As well as performing some logistical functions normally associated with a sexton or verger, church wardens have certain constitutional rights and responsibilities: they may convene and chair meetings of the General Vestry or Select Vestry (but only under certain circumstances), and their consent is required for the use of any experimental forms of service and for any visiting ministers who are not in full communion with the Church of Ireland.
