17 Likewise worthy of praise are the ranks of men and women catechists, well deserving of missionary work to the nations. Imbued with the apostolic spirit, they labor much to make an outstanding and altogether necessary contribution to the spread of the Faith and of the Church. In our time, when there are so few clerics to preach the Gospel to such great numbers and to exercise the pastoral ministry, the position of catechists is of great importance. Therefore their training must be so accomplished and so adapted to advances on the cultural level that as reliable coworkers of the priestly order, they may perform their task well, though it be weighed down with new and greater burdens. There should therefore be an increase in the number of schools, both on the diocesan and on the regional levels, wherein future catechists may study Catholic doctrine, especially in the fields of Scripture and the liturgy, as well as catechetical method and pastoral practice; schools wherein they can develop in themselves a Christian character, and wherein they can devote themselves tirelessly to cultivating piety and sanctity of life. Moreover, conventions or courses should be held in which at certain times catechists could he refreshed in the disciplines and skills useful for their ministry and in which their spiritual life could be nourished and strengthened. In addition, for those who devote themselves entirely to this work, a decent standard of living should be provided, and social security, by paying them a just wage. It would be desirable for the Sacred Congregation for the Propagation of the Faith to provide special funds for the due training and support of catechists. If it seems necessary and fitting, let a special "Opus pro Catechists" be founded. Moreover, the churches should gratefully acknowledge the noble work being done by auxiliary catechists, whose help they will need. These preside over the prayers in their communities and teach sacred doctrine. Something suitable should be done for their doctrinal and spiritual training. Besides, it is to be hoped that, where it seems opportune, catechists who are duly trained should receive a "missio canonica" in a publicly celebrated liturgical ceremony, so that in the eyes of the people they may serve the Faith with greater authority.
