Apostolate of the Laity (Part One)

Indeed, the organic union in this body and the structure of the members are so compact that the member who fails to make his proper contribution to the development of the Church must be said to be useful neither to the Church nor to himself.

They exercise the apostolate in fact by their activity directed to the evangelization and sanctification of men and to the penetrating and perfecting of the temporal order through the spirit of the Gospel. In this way, their temporal activity openly bears witness to Christ and promotes the salvation of men. Since the laity, in accordance with their state of life, live in the midst of the world and its concerns, they are called by God to exercise their apostolate in the world like leaven, with the ardor of the spirit of Christ.

4. Since Christ, sent by the Father, is the source and origin of the whole apostolate of the Church, the success of the lay apostolate depends upon the laity’s living union with Christ, in keeping with the Lord’s words, “He who abides in me, and I in him, bears much fruit, for without me you can do nothing” (John 15:5). This life of intimate union with Christ in the Church is nourished by spiritual aids which are common to all the faithful, especially active participation in the sacred liturgy.(5) These are to be used by the laity in such a way that while correctly fulfilling their secular duties in the ordinary conditions of life, they do not separate union with Christ from their life but rather performing their work according to God’s will they grow in that union. In this way the laity must make progress in holiness in a happy and ready spirit, trying prudently and patiently to overcome difficulties.(6) Neither family concerns nor other secular affairs should be irrelevant to their spiritual life, in keeping with the words of the Apostle, “What-ever you do in word or work, do all in the name of the Lord Jesus Christ, giving thanks to God the Father through Him” (Col. 3:17).

They who have this faith live in the hope of the revelation of the sons of God and keep in mind the cross and resurrection of the Lord. In the pilgrimage of this life, hidden with Christ in God and free from enslavement to wealth, they aspire to those riches which remain forever and generously dedicate themselves wholly to the advancement of the kingdom of God and to the reform and improvement of the temporal order in a Christian spirit. Among the trials of this life they find strength in hope, convinced that “the sufferings of the present time are not worthy to be compared with the glory to come that will be revealed in us” (Rom. 8:18).

This plan for the spiritual life of the laity should take its particular character from their married or family state or their single or widowed state, from their state of health, and from their professional and social activity. They should not cease to develop earnestly the qualities and talents bestowed on them in accord with these conditions of life, and they should make use of the gifts which they have received from the Holy Spirit.

Furthermore, the laity who have followed their vocation and have become members of one of the associations or institutes approved by the Church try faithfully to adopt the special characteristics of the spiritual life which are proper to them as well. They should also hold in high esteem professional skill, family and civic spirit, and the virtues relating to social customs, namely, honesty, justice, sincerity, kindness, and courage, without which no true Christian life can exist.

5. Christ’s redemptive work, while essentially concerned with the salvation of men, includes also the renewal of the whole temporal order. Hence the mission of the Church is not only to bring the message and grace of Christ to men but also to penetrate and perfect the temporal order with the spirit of the Gospel. In fulfilling this mission of the Church, the Christian laity exercise their apostolate both in the Church and in the world, in both the spiritual and the temporal orders. These orders, although distinct, are so connected in the singular plan of God that He Himself intends to raise up the whole world again in Christ and to make it a new creation, initially on earth and completely on the last day. In both orders the layman, being simultaneously a believer and a citizen, should be continuously led by the same Christian conscience.

However, an apostolate of this kind does not consist only in the witness of one’s way of life; a true apostle looks for opportunities to announce Christ by words addressed either to non-believers with a view to leading them to faith, or to the faithful with a view to instructing, strengthening, and encouraging them to a more fervent life. “For the charity of Christ impels us” (2 Cor. 5:14). The words of the Apostle should echo in all hearts, “Woe to me if I do not preach the Gospel” (1 Cor. 9:16).(1) Since, in our own times, new problems are arising and very serious errors are circulating which tend to undermine the foundations of religion, the moral order, and human society itself, this sacred synod earnestly exhorts laymen-each according to his own gifts of intelligence and learning-to be more diligent in doing what they can to explain, defend, and properly apply Christian principles to the problems of our era in accordance with the mind of the Church.
