but most of all, what is a Priest for us? the one who nourish us with the Body and Blood of Christ? the one who always prays for our needs?
PRIESTHOOD. Sacrament of the New Law, instituted by Christ at the Last Supper, which confers on a man the power of consecrating and offering the body and blood of Christ, and of remitting and retaining sins. There are two grades or levels of the priesthood, the presbyterate and the episcopate. Normally priesthood refers to the presbyterate and is the second rank of orders, above the diaconate. Only a bishop can ordain priests, who must first have been ordained deacons. In the ordination of priests, the "matter" of the sacrament is the imposition of the bishop's hands upon the individual candidates, which is done in silence before the consecration prayer, of which the following words pertain to the nature of the order and therefore are required for the validity of the act: "We ask you, all powerful Father, give these servants of yours the dignity of the presbyterate. Renew the Spirit of holiness within them. By your divine gift may they attain the second order of the hierarchy and exemplify right conduct in their lives."
PRIEST. An authorized mediator who offers a true sacrifice in acknowledgment of God's supreme dominion over human beings and in expiation for their sins. A priest's mediation is the reverse of that of a prophet, who communicates from God to the people. A priest mediates from the people to God.
Christ, who is God and man, is the first, last and greatest priest of the New Law. He is the eternal high priest who offered himself once and for all on the Cross, a victim of infinite value, and he continually renews that sacrifice on the altar through the ministry of the Church.
Within the Church are men who are specially ordained as priests to consecrate and offer the body and blood of Christ in the Mass. The Apostles were the first ordained priests, when on Holy Thursday night Christ told them to do in his memory what he had just done at the Last Supper. All priests and bishops trace their ordination to the Apostles. Their second essential priestly power, to forgive sins, was conferred by Christ on Easter Sunday, when he told the Apostles, "For those whose sins you forgive, they are forgiven; for those whose sins you retain, they are retained" (John 20-22, 23).All the Christian faithful, however, also share in the priesthood by their baptismal character. They are enabled to offer themselves in sacrifice with Christ through the Eucharistic liturgy. They offer the Mass in the sense that they internally unite themselves with the outward offering made by the ordained priest alone.
