An apostolate is a Christian organization "directed to serving and evangelizing the world", most often associated with the Anglican Communion or the Catholic Church.[1] In more general usage, an apostolate is an association of persons dedicated to the propagation of a religion or a doctrine. The word apostolate comes from the Greek word apostello, which means to "send forth" or "to dispatch". The Christian origin of the word comes from the twelve apostles who were selected by Christ; they had a "special vocation, a formal appointment of the Lord to a determined office, with connected authority and duties".[2] An apostolate can be a Christian organization made up of the laity or of a specific Christian religious order.
Ministry is something directed to the service of the Church and its members, while apostolate is directed to serving and evangelizing the world.
