Holy Orders is the sacrament through which the mission entrusted by Christ to his apostles continues to be exercised in the Church until the end of time: thus it is the sacrament of apostolic ministry. It includes three degrees: episcopate, presbyterate, and diaconate. (CCC, 1536)

Those interested in a religious vocation should talk to a priest. Fr. Sean Suckiel is the vocations director of the Brooklyn Diocese. The office website can be found at http://www.brooklynpriests.org/.
