In the case of the ordination of priests and bishops, this act confers the sacramental power to ordain (for bishops), baptize, confirm, witness marriages, absolve sins, and consecrate the Eucharist. Deacons can baptize, witness marriages, preach, and assist during the mass, but they cannot consecrate the Eucharist or hear confessions. With the exception of married deacons, an order restored by the Second Vatican Council, all ordained men are to be celibate.
