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 who sense the Lord might be calling them to explore the possibility of becoming a priest or deacon, are strongly encouraged to contact the Vocations Office or their parish priests. Even in the very early stages of discernment, such initial discussions have proven helpful to many.
