God is at work in the “school of the Word of God.”
142. “Blessed is the (one) whom thou dost chasten, O Lord, and whom thou dost teach out of thy law” (Ps 94:12). In the school of the word of God, received in the Church, the disciple, thanks to the gift of the Holy Spirit sent by Christ, grows like his Teacher “in wisdom, stature, and in favour with God and (people)” (Lk 2,52). (They are) also assisted in developing in (themselves) “the divine education” received by means of catechesis and by means of knowledge and experience. (Gravissimum Educationis 4) In this way, by knowing more about the mystery of salvation, by learning to adore God the Father, and “by living in the truth according to charity”, the disciple seeks “to grow in all things towards him, who is the Head, Christ” (Eph 4:15). The pedagogy of God can be said to be completed when the disciple shall “become the perfect (Woman or) Man, fully mature with the fullness of Christ himself” (Eph 4:13). For this reason there cannot be teachers of the faith other than those who are convinced and faithful disciples of Christ and his Church.
Disciples not only faithful, but “convinced.” Convinced by the presence and action of the Spirit? Convinced of the message? Convinced it will be effective?
