Matthew 28:19
"Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,"
Holy Orders is the Sacrament of Apostolic Ministry by which the mission entrusted by Christ to his Apostles continues to be exercised in the Church through the laying on of hands. This sacrament has three distinct degrees or “orders”: deacon, priest, and bishop. All three confer a permanent, sacramental character. (CCC 1536)
