S John Bosco: "great is the goodness"

which, toward those who take refuge in you, you show in the sight of the children of men.

-- Ps 31:20, 21, 22, 23, 24

From the very beginning Christians have brought, along with the bread and wine for the Eucharist, gifts to share with those in need. This custom of the collection, ever appropriate, is inspired by the example of Christ who became poor to make us rich:

Those who are well off, and who are also willing, give as each chooses. What is gathered is given to him who presides to assist orphans and widows, those whom illness or any other cause has deprived of resources, prisoners, immigrants and, in a word, all who are in need.

-- CCC 1351

The family should live in such a way that its members learn to care and take responsibility for the young, the old, the sick, the handicapped, and the poor. There are many families who are at times incapable of providing this help. It devolves then on other persons, other families, and, in a subsidiary way, society to provide for their needs: "Religion that is pure and undefiled before God and the Father is this: to visit orphans and widows in their affliction and to keep oneself unstained from the world."

-- CCC 2208
