The Sacrament of Holy Orders continues Christ's priesthood by ordaining men to serve the Church. There are three levels of ordination: deacon, priest, and bishop. Deacons serve the bishop and help those in need. Priests preach, celebrate the Eucharist, and serve the faithful. Bishops teach the faith and ordain new priests and bishops. Ordination imprints an indelible spiritual mark and configures the man to Christ the priest.
