Catechism of the Catholic Church: Article 6:The Sacrament of Holy Orders
IV. The Celebration of This Sacrament
1572Given the importance that the ordination of a bishop, a priest, or a deacon has for the life of the particular Church, its celebration calls for as many of the faithful as possible to take part. It should take place preferably on Sunday, in the cathedral, with solemnity appropriate to the occasion. All three ordinations, of the bishop, of the priest, and of the deacon, follow the same movement. Their proper place is within the Eucharistic liturgy.
1573The essential rite of the sacrament of Holy Orders for all three degrees consists in the bishop's imposition of hands on the head of the ordinand and in the bishop's specific consecratory prayer asking God for the outpouring of the Holy Spirit and his gifts proper to the ministry to which the candidate is being ordained.
1574As in all the sacraments additional rites surround the celebration. Varying greatly among the different liturgical traditions, these rites have in common the expression of the multiple aspects of sacramental grace. Thus in the Latin Church, the initial rites - presentation and election of the ordinand, instruction by the bishop, examination of the candidate, litany of the saints - attest that the choice of the candidate is made in keeping with the practice of the Church and prepare for the solemn act of consecration, after which several rites symbolically express and complete the mystery accomplished: for bishop and priest, an anointing with holy chrism, a sign of the special anointing of the Holy Spirit who makes their ministry fruitful; giving the book of the Gospels, the ring, the miter, and the crosier to the bishop as the sign of his apostolic mission to proclaim the Word of God, of his fidelity to the Church, the bride of Christ, and his office as shepherd of the Lord's flock; presentation to the priest of the paten and chalice, "the offering of the holy people" which he is called to present to God; giving the book of the Gospels to the deacon who has just received the mission to proclaim the Gospel of Christ.
V. Who Can Confer This Sacrament?
1575Christ himself chose the apostles and gave them a share in his mission and authority. Raised to the Father's right hand, he has not forsaken his flock but he keeps it under his constant protection through the apostles, and guides it still through these same pastors who continue his work today. Thus, it is Christ whose gift it is that some be apostles, others pastors. He continues to act through the bishops.
1576Since the sacrament of Holy Orders is the sacrament of the apostolic ministry, it is for the bishops as the successors of the apostles to hand on the "gift of the Spirit," the "apostolic line." Validly ordained bishops, i.e., those who are in the line of apostolic succession, validly confer the three degrees of the sacrament of Holy Orders.
VI. Who Can Receive This Sacrament?
1577"Only a baptized man (vir) validly receives sacred ordination." The Lord Jesus chose men (viri) to form the college of the twelve apostles, and the apostles did the same when they chose collaborators to succeed them in their ministry. The college of bishops, with whom the priests are united in the priesthood, makes the college of the twelve an ever-present and ever-active reality until Christ's return. The Church recognizes herself to be bound by this choice made by the Lord himself. For this reason the ordination of women is not possible.
1578No one has a right to receive the sacrament of Holy Orders. Indeed no one claims this office for himself; he is called to it by God. Anyone who thinks he recognizes the signs of God's call to the ordained ministry must humbly submit his desire to the authority of the Church, who has the responsibility and right to call someone to receive orders. Like every grace this sacrament can be received only as an unmerited gift.
1579All the ordained ministers of the Latin Church, with the exception of permanent deacons, are normally chosen from among men of faith who live a celibate life and who intend to remain celibate "for the sake of the kingdom of heaven." Called to consecrate themselves with undivided heart to the Lord and to "the affairs of the Lord," they give themselves entirely to God and to men. Celibacy is a sign of this new life to the service of which the Church's minister is consecrated; accepted with a joyous heart celibacy radiantly proclaims the Reign of God.
1580In the Eastern Churches a different discipline has been in force for many centuries: while bishops are chosen solely from among celibates, married men can be ordained as deacons and priests. This practice has long been considered legitimate; these priests exercise a fruitful ministry within their communities. Moreover, priestly celibacy is held in great honor in the Eastern Churches and many priests have freely chosen it for the sake of the Kingdom of God. In the East as in the West a man who has already received the sacrament of Holy Orders can no longer marry.
