Carmelites undertake various forms of apostolate and service requested by the Church. While Carmelites are members of an international Order, they normally work within a local Church and play their part in the pastoral plan of the Diocese. Sometimes, the Order undertakes responsibility for parish work on behalf of a Diocese.
A parish is often defined legally as being a community of the Christian faithful formally constituted in a particular church, whose pastoral care is entrusted to a pastor under the authority of the diocesan bishop.
