No methodology, no matter how well tested, can dispense with the person of the catechist in every phase of the catechetical process. The charism given to him by the Spirit, a solid spirituality and transparent witness of life, constitutes the soul of every method. Only his own human and Christian qualities guarantee a good use of texts and other work instruments. The catechist is essentially a mediator. He facilitates communication between the people and the mystery of God, between subjects amongst themselves, as well as with the community. For this reason, his cultural vision, social condition and lifestyle must not be obstacles to the journey of faith. Rather, these help to create the most advantageous conditions for seeking out, welcoming and deepening the Christian message. He does not forget that belief is a fruit of grace and liberty. Thus, he ensures that his activities always draw support from faith in the Holy Spirit and from prayer. Finally, the personal relationship of the catechist with the subject is of crucial importance. The activity and creativity of the catechized 18DCG (1971) 75.
The active participation of all the catechized in their formative process is completely in harmony, not only with genuine human communication, but specifically with the economy of Revelation and salvation. Believers, indeed, in the ordinary state of Christian life, individually or in age groups, are called to respond to the gift of God through prayer, participation in the sacraments, the liturgy, ecclesial and social commitment, works of charity and promotion of human values, such as liberty, justice and peace and the protection of creation. In catechesis, therefore, subjects take on a commitment in activities of faith, hope and charity, to acquire the capacity and rectitude of judges, to strengthen their personal conversion, and to a Christian praxis in their lives. The same subjects, especially if adults, can contribute to catechesis, by pointing out the most effective ways of understanding and expressing the message such as: "learning while doing", by employing research 'and dialogue, by exchanging challenging points of view.
