All human education and all real communication require first of all that interior activity be made possible and be stimulated in the one to whom they are directed. In catechesis, therefore, one must stir up the activity of faith (of hope, too, and of charity); for correctness and vigor of judgment, which are to be stimulated by an active style of instruction, here help to bring about acceptance of the word of God. But the confidence which inspires active education should never lead one to forget that the act of faith necessarily involves a conversion of the one making it.
This active way of catechizing is in complete harmony with the economy of revelation and salvation. The pedagogical art which promotes an active response on the part of those to be catechized is in harmony with the general condition of the Christian life in which the faithful actively respond to God's gifts through prayers, through participation in the sacraments and the sacred liturgy, through acceptance of responsibilities in the Church and in social life, and through the practice of charity.
Those to be taught, especially if they are adults, can contribute in an active way to the progress of the catechesis. Thus, they should be asked how they understand the Christian message and how they can explain it in their own words. Then a comparison should be made between the results of that questioning and what is taught by the Magisterium of the Church, and only those things which are in agreement with the faith should be approved. In this way powerful aids can be found to hand on effectively the one true Christian message.
