Teach the Fundamentals of the Faith
4. Therefore with the example of St. Charles Borromeo before Us, We encourage you and implore you by the mercy of Jesus Christ not to despair in this important work of handing on the fundamentals of the Christian faith, even if hitherto you have devoted all your zeal and care to it. See to it that every minister performs carefully the measures laid down by the holy Council of Trent and by the statutes of your synods: that on fixed days school-masters and mistresses should teach Christian doctrine; that confessors should perform this part of their duty whenever anyone stands at their tribunal who does not know what he must by necessity of means know to be saved; that priests should also provide this instruction before uniting spouses in marriage; that fathers of families and lords of houses should be gravely advised of the duty imposed on them of being themselves instructed and of seeing to the instruction in the commandments of Christian doctrine of their sons and of the members of their household; that the practice of reciting aloud properly-composed acts of Faith, Hope and Charity by the priest and people before or after the parish mass should be preserved in the dioceses in which it is customary and be carefully introduced where it is not...Preachers should also follow this path, recalling the salutary advice that they should join instruction to exhortation whenever their hearers stand in need of both.
Finally, the best method for instructing ignorant men in Christian doctrine is indicated by St. Augustine who says (de Cath. Rud., 10) that the most fruitful procedure is to ask questions in a friendly fashion after the explanation; from this questioning one can learn whether each one understood what he heard or whether the explanation needs repeating. In order that the learner grasp the matter, "we must ascertain by questioning whether the one being catechised has understood, and in accordance with his response, we must either explain more clearly and fully or not dwell further on what is known to them, etc. But if a man is very slow, he must be mercifully helped and the most necessary doctrines especially should be briefly imparted to him." We are assured that you yourselves will pursue many more paths than We point out to you in this encyclical letter. In the meantime, Venerable Brothers, We lovingly impart to you and to the flock entrusted to your care Our Apostolic Blessing.
