What is a Catholic priest? What is the nature of the priesthood?

(Text  from the decree “Presbyterorum ordinis”, on the ministry and life of priests, of the Second Vatican Council, issued by the Commission on the Discipline of the Clergy, being Blessed Mons. Alvaro del Portillo the secretary)

By the sacrament of Orders priests are formed in the image of Christ the Priest, to be ministers of Christ the Head in constructing and building up his whole Body, the Church, as fellow-workers with the order of bishops. In the consecration of baptism they have already received, in common with all Christians, the sign and gift of so great a vocation and grace that, even in their human weakness, they have the power, and the duty, to seek perfection, in accordance with our Lord’s words: Be perfect, then, as your Father in heaven is also perfect.

Priests are obligated in a special way to acquire this perfection. By receiving holy Orders they have been consecrated in a new way, and made living instruments of Christ the eternal Priest, so as to be able to continue through the years Christ’s wonderful work which, by divine power, has restored to wholeness the entire family of man.

Since each priest acts, as far as he may, in the person of Christ himself, he is given special grace to help him grow toward the perfection of the one whose role he plays, as he ministers to his flock and the whole people of God. He receives grace for the healing of human weakness from the holiness of Christ, who became for us a high priest, holy, innocent, undefiled, separated from sinners.

Christ, whom the Father sanctified, that is, consecrated, and sent into the world, gave himself for us, to redeem us from all sin, and to purify for himself an acceptable people, zealous for good works. So, through his passion he entered into his glory. In the same way, priests, consecrated as they are by the anointing of the Holy Spirit and sent by Christ, put an end in their lives to the sins of our selfish nature, and give themselves wholly to the service of mankind, and so are enabled to grow to perfect manhood in the holiness with which they are enriched in Christ.

As they exercise the ministry of the Spirit and of holiness, they are strengthened in the spiritual life, provided that they are docile to Christ’s Spirit, who gives them life and is their guide. By the sacred actions they perform daily, and by their entire ministry in communion with their bishop and fellow-priests, they are set on the way that leads to perfection.

The holiness of priests is itself an important contribution to the fruitfulness of their ministry. It is true that God’s grace can effect the work of salvation even through unworthy ministers, but God ordinarily prefers to show his wonders by means of those who are more submissive to the inspiration and guidance of the Holy Spirit, and, who through close union with Christ and holiness of life, are able to say with Saint Paul: I live, but no longer is it I who live, it is Christ who lives within me.

The work that the Church carries out in the world would be incomprehensible unless the Holy Spirit dwells on it

Saint John wrote: “On the last day of the festival, Jesus cried out: Streams of living water will flow from the hearts of all who believe in me. If anyone is thirsty, let him come to me and drink. Streams of living water will flow from his heart. He was speaking of the Spirit whom all believers would receive” (John 7:37-39)

And the dogmatic constitution on the Church of the Second Vatican Council, explains:

When the Son completed the work with which the Father had entrusted him on earth, the Holy Spirit was sent on the day of Pentecost to sanctify the Church unceasingly, and thus enable believers to have access to the Father through Christ in the one Spirit. He is the Spirit of life, the fountain of water welling up to give eternal life. Through him the Father gives life to men, dead because of sin, until he raises up their mortal bodies in Christ.

The Spirit dwells in the Church and in the hearts of the faithful as in a temple. He prays in them and bears witness in them to their adoption as sons. He leads the Church into all truth and gives it unity in communion and in service. He endows it with different hierarchical and charismatic gifts, directs it by their means, and enriches it with his fruits.

By the power of the Gospel he enables the Church to grow young, perpetually renews it, and leads it to complete union with its Bridegroom. For the Spirit and the Bride say to the Lord Jesus: “Come!”
In this way the Church reveals itself as a people whose unity has its source in the unity of Father, Son and Holy Spirit.

The whole company of the faithful, who have an anointing by the Holy Spirit, cannot err in faith. They manifest this distinctive characteristic of theirs in the supernatural instinct of faith (sensus fidei) of the whole people when, from the bishops to the most ordinary lay person among the faithful, they display a universal agreement on matters of faith and morals.

This instinct of faith is awakened and kept in being by the Spirit of truth. Through it the people of God hold indefectibly to the faith once delivered to the saints, penetrate it more deeply by means of right judgment, and apply it more perfectly in their lives. They do all this under the guidance of the sacred teaching office: by faithful obedience to it they receive, not the word of men but in truth the word of God.

Moreover, the Holy Spirit not only sanctifies and guides God’s people by the sacraments and the ministries, and enriches it with virtues, he also distributes special graces among the faithful of every state of life, assigning his gifts to each as he chooses. By means of these special gifts he equips them and makes them eager for various activities and responsibilities that benefit the Church in its renewal or its increase, in accordance with the text: To each is given the manifestation of the Spirit for a good purpose.
These charisms, the simpler and more widespread as well as the most outstanding, should be accepted with a sense of gratitude and consolation, since in a very special way they answer and serve the needs of the Church.
