The Church performs this kind of function chiefly by means of catechesis (cf. DV, 24). By drawing the truth from the word of God and faithfully adhering to the secure expression of this word, catechesis strives to teach this word of God with complete fidelity. The function of catechesis, however, cannot be restricted to repetition of traditional formulas; in fact, it demands that these formulas be understood, and be faithfully expressed in language adapted to the intelligence of the hearers, using even new methods when necessary. The language will be different for different age levels, social conditions of men, human cultures, and forms of civil life (cf. DV, 8; CD, 14).
