During the rite of ordination, after the bishop, the priests present lay their hands on the ordinands
The sacrament of holy orders in the Catholic Church includes three orders: bishop, priest, and deacon. In the phrase "holy orders", the word "holy" simply means "set apart for some purpose." The word "order" designates an established civil body or corporation with a hierarchy, and ordination means legal incorporation into an order. In context, therefore, a group with a hierarchical structure that is set apart for ministry in the Church.
For Catholics, the church views typically that in the last year of seminary training a man will be ordained to the "transitional diaconate." Thisdistinguishes men bound for priesthood from those who have entered the "permanent diaconate" and do not intend to seek ordination as a priest. Deacons, whether transitional or permanent, receive faculties to preach, to perform baptisms, and to witness marriages. They may assist at the Eucharist or the Mass, but are not the ministers of the Eucharist. After six months or more as a transitional deacon, a man will be ordained to the priesthood. Priests are able to preach, perform baptisms, witness marriages, hear confessions and give absolutions, anoint the sick, and celebrate the Eucharist or the Mass. Some priests are later chosen to be bishops; bishops may ordain priests, deacons, and bishops.
Bishops are chosen from among the priests in the Catholic Church. Among Eastern Catholic Churches, which permit married priests, bishops must be widowers or unmarried, or agree to abstain from sexual contact with their wives. It is a common misconception that all such bishops come from religious orders. While this is generally true, it is not an absolute rule. Catholic bishops are usually leaders of territorial units called dioceses.
Normally, bishops administer the sacrament of holy orders. In Latin-rite Catholic churches, only bishops (and priests with authorization by the local bishop) may licitly administer the sacrament of confirmation, but if an ordinary priest administers that sacrament illicitly, it is nonetheless considered valid, so that the person confirmed cannot be actually confirmed again, by a bishop or otherwise. Latin rite priests with special permission of the diocesan bishop or the Holy See can lawfully administer confirmation; every Catholic priest must administer confirmation, even without permission, to children in danger of death. In Eastern Catholic Churches, confirmation is done by parish priests via the rite of chrismation, and is usually administered to both babies and adults immediately after their baptism.
