Sacred ministers, those who serve the spiritual needs of others, in the Catholic Church are ordained by a bishop and by means of a special sacrament called Holy Orders, which creates the hierarchy of deacon, priest, and bishop. This sacrament can be received only once, just like Baptism and Confirmation, but a man may also be ordained to a higher order up to the third degree. A man must first be ordained a deacon before being ordained a priest, and he must be ordained a deacon and then a priest before being ordained a bishop. Every priest and every bishop has experienced the Sacrament of Holy Orders more than once, yet he can never be re-ordained a deacon, priest or bishop. Only baptized men can receive the Sacrament of Holy Orders.
