Saint Peter Chrysologus: "speak to the people"

"Where did this man get such wisdom?"

-- Mt 13:54-58

The Magisterium of the Pastors of the Church in moral matters is ordinarily exercised in catechesis and preaching, with the help of the works of theologians and spiritual authors. Thus from generation to generation, under the aegis and vigilance of the pastors, the "deposit" of Christian moral teaching has been handed on, a deposit composed of a characteristic body of rules, commandments, and virtues proceeding from faith in Christ and animated by charity. Alongside the Creed and the Our Father, the basis for this catechesis has traditionally been the Decalogue which sets out the principles of moral life valid for all men.

From Saint Peter Chrysologus:

"We ask God to hallow his name, which by its own holiness saves and makes holy all creation . . . . It is this name that gives salvation to a lost world. But we ask that this name of God should be hallowed in us through our actions. For God's name is blessed when we live well, but is blasphemed when we live wickedly. As the Apostle says: "The name of God is blasphemed among the Gentiles because of you." We ask then that, just as the name of God is holy, so we may obtain his holiness in our souls."

-- CCC 2814

"The Father in heaven urges us, as children of heaven, to ask for the bread of heaven. [Christ] himself is the bread who, sown in the Virgin, raised up in the flesh, kneaded in the Passion, baked in the oven of the tomb, reserved in churches, brought to altars, furnishes the faithful each day with food from heaven."
