31 Various types of the apostolate demand also a specially suitable formation.
a) In regard to the apostolate for evangelizing and sanctifying men, the laity must be specially formed to engage in conversation with others, believers, or non-believers, in order to manifest Christ's message to all men.(5)
Since in our times, different forms of materialism are spread far and wide even among Catholic, the laity should not only learn doctrine more diligently, especially those main points which are the subjects of controversy, but should also exhibit the witness of an evangelical life in contrast to all forms of materialism.
b) In regard to the Christian renewal of the temporal order, the laity should be instructed in the true meaning and value of temporal things, both in themselves and in relation to all the aims of the human person. They should be trained in the right use of things and the organization of institutions, attentive always to the common good in line with the principles of the moral and social teaching of the Church. Laymen should above all learn the principles and conclusions of the social doctrine so as to become capable of working for the development of this doctrine to the best of their ability and of rightly applying these same principles and conclusions to individual cases.(6)
c) Since the works of charity and mercy express the most striking testimony of the Christian life, apostolic formation should lead also to the performance of these works so that the faithful may learn from childhood on to have compassion for their brethren and to be generous in helping those in need.(7)

32 There are many aids for lay persons devoted to the apostolate, namely, study sessions, congresses, periods of recollection, spiritual exercises, frequent meetings, conferences, books, and periodicals directed toward the acquisition of a deeper knowledge of sacred Scripture and Catholic doctrine, the nourishment.of spiritual life, the discernment of world conditions, and the discovery and development of suitable methods.(8)
These aids in formation take into consideration the various types of the apostolate in the milieu where it is exercised.
For this purpose also centers or higher institutes have been erected, and they have already proved highly successful.
The most holy council rejoices over projects of this kind which are already flourishing in certain areas, and it desires that they may be promoted also in other areas where they may be needed. Furthermore, centers of documentation and study not only in theology but also in anthropology, psychology, sociology, and methodology should be established for all fields of the apostolate for the better development of the natural capacities of the laity-men and women, young persons and adults.

33 The most holy council, then, earnestly entreats all the laity in the Lord to answer gladly, nobly, and promptly the more urgent invitation of Christ in this hour and the impulse of the Holy Spirit. Younger persons should feel that this call has been directed to them especially and they should respond to it eagerly and generously. Through this holy synod, the Lord renews His invitation to all the laity to come closer to Him every day, recognizing that what is His is also their own (Ph 2,5), to associate themselves with Him in His saving mission. Once again He sends them into every town and place where He will come (cf. Lc 10,1) so that they may show that they are co-workers in the various forms and modes of the one apostolate of the Church, which must be constantly adapted to the new needs of our times. Ever productive as they should be in the work of the Lord, they know that their labor in Him is not in vain (cf. 1Co 15,58).
