When we leave Mass, we ought to go out the way Moses descended Mt Sinai: with his face shining, with his heart brave and strong to face the world's difficulties.

You know that the air and water are being polluted, as is everything we touch and live with, and we go on corrupting the nature that we need. We don't realize we have a commitment to God to take care of nature. To cut down a tree, to waste water when there is so much lack of it, to let buses poison our atmosphere with those noxious fumes from their exhausts, to burn rubbish haphazardly-all that concerns our alliance with God.

God is not satisfied with appearance. God wants the garment of justice. God wants his Christians dressed in love.

When we speak for the poor, please note that we do not take sides with one social class. What we do is invite all social classes, rich and poor, without distinction, saying to everyone let us take seriously the cause of the poor as though it were our own.

Social sin is the crystallization ... of individuals' sins into permanent structures that keeps sin in being and makes its force to be felt by the majority of people.

The church would betray its own love for God and its fidelity to the gospel if it stopped being . . . a defender of the rights of the poor . . . a humanizer of every legitimate struggle to achieve a more just society . . . that prepares the way for the true reign of God in history.

We must not seek the child Jesus in the pretty figures of our Christmas cribs. We must seek him among the undernourished children who have gone to bed at night with nothing to eat, among the poor newsboys who will sleep covered with newspapers in doorways.
