"The Spirit of God is upon me; he has anointed me. He sent me to bring
good news to the poor, and to heal the broken hearted. You are a priest for
ever, a priest like Melchizedech of old."
Luke 4:18; Ps.109:4
Holy Orders is the first of the sacraments which are there to serve the
people. Those who receive this sacrament are consecrated in the name of
Christ to nourish God's people the Church, by brining them the Word of God
and offering the sacrifice of the Mass. It is a sacrament of apostolic
ministry since it continues, until the end of time, the ministry of the
apostles entrusted to them by Christ.
This sacrament is called 'Orders' because the word 'ordo' comes from an
ancient Roman word which designated an established civil body, especially a
governing body. The Church has a number of 'ordos': the order of bishops,
the order of priests and the order of deacons, to name but three. All are
part of the sacrament of holy orders and integration into one of these
'ordos' is called ordination. Ordination confers on the candidate the
ability to exercise sacred power which can only come from Christ himself
through his Church. It sets the individual apart for sacred duty and
therefore it is also a consecration. The bishop alone has the power to
ordain and he does so by the laying on of hands and the praying of the
consecratory prayer. This is the visible sign of the sacrament which is
reinforced by the anointing of the new priests hands with chrism and the
giving of the chalice and paten.
The New Testament tells us that all the baptised are a priestly people, that
is, through our baptism, we all share in the one priesthood of Christ.
Through the sacrament of Holy Orders, however, the one ordained enters the
ministerial priesthood therefore participating in the priesthood of Christ in
a different way. This ministerial priesthood is directed towards the service
of the Church in a specific way, building it up and leading it forward. When
the ordained minister celebrates the Liturgy it is Christ himself who is
present. So, for example, when a priest baptises, or forgives sin or
anoints, it is Christ who is doing these things through his instrument, the
officiating priest. The ordained priest, therefore, acts in the name of
Christ.
The reception of holy orders, as in the case of baptism and confirmation,
confers on the one who receives it an indelible spiritual character which
cannot be repeated. Once conferred it cannot be removed for "You are a
priest for ever" (Ps.109:4). As the Catechism of the Catholic Church says:
"The grace of the Holy Spirit proper to this sacrament is configuration to
Christ as Priest, Teacher and Pastor, of whom the ordained is made a
minister." (Art. 1585).
