Put to death, then, the parts of you that are earthly: immorality, impurity, passion, evil desire, and the greed that is idolatry. Because of these the wrath of God is coming [upon the disobedient]. By these you too once conducted yourselves, when you lived in that way. But now you must put them all away: anger, fury, malice, slander, and obscene language out of your mouths. Stop lying to one another, since you have taken off the old self with its practices and have put on the new self, which is being renewed, for knowledge, in the image of its creator. Here there is not Greek and Jew, circumcision and uncircumcision, barbarian, Scythian, slave, free; but Christ is all and in all. Put on then, as God’s chosen ones, holy and beloved, heartfelt compassion, kindness, humility, gentleness, and patience, bearing with one another and forgiving one another, if one has a grievance against another; as the Lord has forgiven you, so must you also do. And over all these put on love, that is, the bond of perfection. And let the peace of Christ control your hearts, the peace into which you were also called in one body. And be thankful. Let the word of Christ dwell in you richly, as in all wisdom you teach and admonish one another, singing psalms, hymns, and spiritual songs with gratitude in your hearts to God. And whatever you do, in word or in deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him.

Colossians 3: 5-17

"The word of Christ": the whole corpus of our Lord's teachings, of which the Apostles are accredited witnesses. This should be ever-present to the Christian's soul and "dwell... richly" in him, imbuing everything he does: the word of Christ is the best nourishment of one's life of prayer and an inexhaustible source of practical teaching; and it is to be found in the first instance in the books of the New Testament. St John Chrysostom says that these writings "are teachers which never cease to instruct us [...]. Open these books. What a treasury of good remedies they contain! [...]. All you need do is look at the book, read it and remember well the wise teachings therein. The source of all our evils is our ignorance of the sacred books" (Hom, on Col, ad loc.).St Paul also reminds us that our appreciation should lead us to glorify the Lord with songs of joy and gratitude. We can use ready-made hymns for this purpose, and also the Psalms, which the Church has always used in its liturgy to praise God and to nourish the spiritual life.

"Just as the mouth savors good food, so does the heart savor the Psalms"

"Christ . . . fulfills this prophetic office, not only by the hierarchy . . . but also by the laity. He accordingly both establishes them as witnesses and provides them with the sense of the faith [sensus fidei] and the grace of the word" To teach in order to lead others to faith is the task of every preacher and of each believer.

Lay people who are capable and trained may also collaborate in catechetical formation, in teaching the sacred sciences, and in use of the communications media.
