The Sacrament of Holy Orders continues Christ's mission through the Apostles by establishing an ordained priesthood to lead the Church. There are three degrees of Holy Orders - bishops, priests, and deacons - with bishops and priests able to celebrate the sacraments. At ordination, candidates undergo examination, promise obedience, receive the laying on of hands by the bishop, and anointing with chrism as a sign of their consecration to serve God's people by preaching, administering sacraments, and building up the Church.
