11. It is through the sacraments and the exercise of the virtues that the sacred nature and organic structure of the priestly community is brought into operation. Incorporated in the Church through baptism, the faithful are destined by the baptismal character for the worship of the Christian religion; reborn as sons of God they must confess before men the faith which they have received from God through the Church. They are more perfectly bound to the Church by the sacrament of Confirmation, and the Holy Spirit endows them with special strength so that they are more strictly obliged to spread and defend the faith, both by word and by deed, as true witnesses of Christ. Taking part in the Eucharistic sacrifice, which is the fount and apex of the whole Christian life, they offer the Divine Victim to God, and offer themselves along with It.(6*) Thus both by reason of the offering and through Holy Communion all take part in this liturgical service, not indeed, all in the same way but each in that way which is proper to himself. Strengthened in Holy Communion by the Body of Christ, they then manifest in a concrete way that unity of the people of God which is suitably signified and wondrously brought about by this most august sacrament.
Those who approach the sacrament of Penance obtain pardon from the mercy of God for the offence committed against Him and are at the same time reconciled with the Church, which they have wounded by their sins, and which by charity, example, and prayer seeks their conversion. By the sacred anointing of the sick and the prayer of her priests the whole Church commends the sick to the suffering and glorified Lord, asking that He may lighten their suffering and save them; she exhorts them, moreover, to contribute to the welfare of the whole people of God by associating themselves freely with the passion and death of Christ. Those of the faithful who are consecrated by Holy Orders are appointed to feed the Church in Christ’s name with the word and the grace of God. Finally, Christian spouses, in virtue of the sacrament of Matrimony, whereby they signify and partake of the mystery of that unity and fruitful love which exists between Christ and His Church, help each other to attain to holiness in their married life and in the rearing and education of their children. By reason of their state and rank in life they have their own special gift among the people of God. From the wedlock of Christians there comes the family, in which new citizens of human society are born, who by the grace of the Holy Spirit received in baptism are made children of God, thus perpetuating the people of God through the centuries. The family is, so to speak, the domestic church. In it parents should, by their word and example, be the first preachers of the faith to their children; they should encourage them in the vocation which is proper to each of them, fostering with special care vocation to a sacred state.
Fortified by so many and such powerful means of salvation, all the faithful, whatever their condition or state, are called by the Lord, each in his own way, to that perfect holiness whereby the Father Himself is perfect.
12. The holy people of God shares also in Christ’s prophetic office; it spreads abroad a living witness to Him, especially by means of a life of faith and charity and by offering to God a sacrifice of praise, the tribute of lips which give praise to His name. The entire body of the faithful, anointed as they are by the Holy One, cannot err in matters of belief. They manifest this special property by means of the whole peoples’ supernatural discernment in matters of faith when “from the Bishops down to the last of the lay faithful” they show universal agreement in matters of faith and morals. That discernment in matters of faith is aroused and sustained by the Spirit of truth. It is exercised under the guidance of the sacred teaching authority, in faithful and respectful obedience to which the people of God accepts that which is not just the word of men but truly the word of God. Through it, the people of God adheres unwaveringly to the faith given once and for all to the saints, penetrates it more deeply with right thinking, and applies it more fully in its life.
It is not only through the sacraments and the ministries of the Church that the Holy Spirit sanctifies and leads the people of God and enriches it with virtues, but, “allotting his gifts to everyone according as He wills, He distributes special graces among the faithful of every rank. By these gifts He makes them fit and ready to undertake the various tasks and offices which contribute toward the renewal and building up of the Church, according to the words of the Apostle: “The manifestation of the Spirit is given to everyone for profit”. These charisms, whether they be the more outstanding or the more simple and widely diffused, are to be received with thanksgiving and consolation for they are perfectly suited to and useful for the needs of the Church. Extraordinary gifts are not to be sought after, nor are the fruits of apostolic labor to be presumptuously expected from their use; but judgment as to their genuinity and proper use belongs to those who are appointed leaders in the Church, to whose special competence it belongs, not indeed to extinguish the Spirit, but to test all things and hold fast to that which is good.
35. Christ, the great Prophet, who proclaimed the Kingdom of His Father both by the testimony of His life and the power of His words, continually fulfills His prophetic office until the complete manifestation of glory. He does this not only through the hierarchy who teach in His name and with His authority, but also through the laity whom He made His witnesses and to whom He gave understanding of the faith (sensu fidei) and an attractiveness in speech so that the power of the Gospel might shine forth in their daily social and family life. They conduct themselves as children of the promise, and thus strong in faith and in hope they make the most of the present, and with patience await the glory that is to come. Let them not, then, hide this hope in the depths of their hearts, but even in the program of their secular life let them express it by a continual conversion and by wrestling “against the world‐rulers of this darkness, against the spiritual forces of wickedness.
Just as the sacraments of the New Law, by which the life and the apostolate of the faithful are nourished, prefigure a new heaven and a new earth, so too the laity go forth as powerful proclaimers of a faith in things to be hoped for, when they courageously join to their profession of faith a life springing from faith. This evangelization, that is, this announcing of Christ by a living testimony as well as by the spoken word, takes on a specific quality and a special force in that it is carried out in the ordinary surroundings of the world.
In connection with the prophetic function is that state of life which is sanctified by a special sacrament obviously of great importance, namely, married and family life. For where Christianity pervades the entire mode of family life, and gradually transforms it, one will find there both the practice and an excellent school of the lay apostolate. In such a home husbands and wives find their proper vocation in being witnesses of the faith and love of Christ to one another and to their children. The Christian family loudly proclaims both the present virtues of the Kingdom of God and the hope of a blessed life to come. Thus by its example and its witness it accuses the world of sin and enlightens those who seek the truth.
Consequently, even when preoccupied with temporal cares, the laity can and must perform a work of great value for the evangelization of the world. For even if some of them have to fulfill their religious duties on their own, when there are no sacred ministers or in times of persecution; and even if many of them devote all their energies to apostolic work; still it remains for each one of them to cooperate in the external spread and the dynamic growth of the Kingdom of Christ in the world. Therefore, let the laity devotedly strive to acquire a more profound grasp of revealed truth, and let them insistently beg of God the gift of wisdom.
