Purification of Spirit through Fasting and Alms giving
From a sermon of Saint Leo the Great, pope

Dear friends, at every moment the earth is full of the mercy of God, and nature itself is a lesson for all the faithful in the worship of God. The heavens, the sea and all that is in them bear witness to the goodness and omnipotence of their Creator, and the marvelous beauty of the elements as they obey him demands from the intelligent creation a fitting expression of its gratitude.

But with the return of that season marked out in a special way by the mystery of our redemption, and of the days that lead up to the paschal feast, we are summoned more urgently to prepare ourselves by a purification of spirit.

The special note of the paschal feast is this: the whole Church rejoices in the forgiveness of sins. It rejoices in the forgiveness not only of those who are then reborn in holy baptism but also of those who are already numbered among God’s adopted children.

Initially, men are made new by the rebirth of baptism. Yet there still is required a daily renewal to repair the shortcomings of our mortal nature, and whatever degree of progress has been made there is no one who should not be more advanced. All must therefore strive to ensure that on the day of redemption no one may be found in the sins of his former life.

Dear friends, what the Christian should be doing at all times should be done now with greater care and devotion, so that the Lenten fast enjoined by the apostles may be fulfilled, not simply by abstinence from food but above all by the renunciation of sin.
