From a letter to the Corinthians by Saint Clement, Pope
Repent

Let us fix our attention on the blood of Christ and recognize how precious it is to God his Father, since it was shed for our salvation and brought the grace of repentance to all the world.

If we review the various ages of history, we will see that in every generation the Lord has offered the opportunity of repentance to any who were willing to turn to him. When Noah preached God’s message of repentance, all who listened to him were saved. Jonah told the Ninevites they were going to be destroyed, but when they repented, their prayers gained God’s forgiveness for their sins, and they were saved, even though they were not of God’s people.

Under the inspiration of the Holy Spirit, the ministers of God’s grace have spoken of repentance; indeed, the Master of the whole universe himself spoke of repentance with an oath: As I live, says the Lord, I do not wish the death of the sinner but his repentance. He added this evidence of his goodness: House of Israel, repent of your wickedness. Tell the sons of my people: If their sins should reach from earth to heaven, if they are brighter than scarlet and blacker than sackcloth, you need only turn to me with your whole heart and say, “Father”, and I will listen to you as a holy people.

In other words, God wanted all his beloved ones to have the opportunity to repent and he confirmed this desire by his own almighty will. That is why we should obey his sovereign and glorious will and prayerfully entreat his mercy and kindness. We should be suppliant before him and turn to his compassion, rejecting empty works and quarrelling and jealousy which only lead to death.

Brothers, we should be humble in mind, putting aside all arrogance, pride and foolish anger. Rather, we should act in accordance with the Scriptures, as the Holy Spirit says: The wise man must not glory in his wisdom nor the strong man in his strength nor the rich man in his riches. Rather, let him who glories glory in the Lord by seeking him and doing what is right and just. Recall especially what the Lord Jesus said when he taught gentleness and forbearance. Be merciful, he said, so that you may have mercy shown to you. Forgive, so that you may be forgiven. As you treat others, so you will be treated. As you give, so you will receive. As you judge, so you will be judged. As you are kind to others, so you will be treated kindly. The measure of your giving will be the measure of your receiving.

Let these commandments and precepts strengthen us to live in humble obedience to his sacred words. As Scripture asks: Whom shall I look upon with favour except the humble, peaceful man who trembles at my words?

Sharing then in the heritage of so many vast and glorious achievements, let us hasten toward the goal of peace, set before us from the beginning. Let us keep our eyes firmly fixed on the Father and Creator of the whole universe, and hold fast to his splendid and transcendent gifts of peace and all his blessings.

From a sermon by Saint Leo the Great, pope
(Sermo 6 de Quadragesima, 1-2: PL 54, 285-287)
Purification of spirit through fasting and almsgiving

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.

There is no more profitable practice as a companion to holy and spiritual fasting than that of almsgiving. This embraces under the single name of mercy many excellent works of devotion, so that the good intentions of all the faithful may be of equal value, even where their means are not. The love that we owe both God and man is always free from any obstacle that would prevent us from having a good intention. The angels sang: Glory to God in the highest, and peace to his people on earth. The person who shows love and compassion to those in any kind of affliction is blessed, not only with the virtue of good will but also with the gift of peace.

The works of mercy are innumerable. Their very variety brings this advantage to those who are true Christians, that in the matter of almsgiving not only the rich and affluent but also those of average means and the poor are able to play their part. Those who are unequal in their capacity to give can be equal in the love within their hearts.

(Supp. Hom. 6 De precatione: PG 64, 462-466)
Prayer is the light of the spirit

Prayer and converse with God is a supreme good: it is a partnership and union with God. As the eyes of the body are enlightened when they see light, so our spirit, when it is intent on God, is illumined by his infinite light. I do not mean the prayer of outward observance but prayer from the heart, not confined to fixed times or periods, but continuous throughout the day and night.

Our spirit should be quick to reach out toward God not only when it is engaged in meditation; at other times also, when it is carrying out its duties, caring for the needy, performing works of charity, giving generously in the service of others, our spirit should long for God, and call him to mind, so that these works may be seasoned with the salt of God's love, and so make a palatable offering to the Lord of the universe. Throughout the whole of our lives we may enjoy the benefit that comes from prayer if we devote a great deal of time to it.

Prayer is the light of the spirit, true knowledge of God, mediating between God and man. The spirit, raised up to heaven by prayer, clings to God with the utmost tenderness; like a child crying tearfully for its mother, it craves the milk that God provides. It seeks the satisfaction of its own desires, and receives gifts outweighing the whole world of nature.

Prayer stands before God as an honored ambassador. It gives joy to the spirit, peace to the heart. I speak of prayer, not words. It is the longing for God, love too deep for words, a gift not given by man but by God's grace. The apostle Paul says: "We do not know how we are to pray but the Spirit himself pleads for us with inexpressible longings."

When the Lord gives this kind of prayer to someone; he gives him riches that cannot be taken away, heavenly food that satisfies the spirit. One who tastes this food is set on fire with an eternal longing for the Lord: his spirit burns as in a fire of the utmost intensity.

Practice prayer from the beginning. Paint your house with the colors of modesty and humility. Make it radiant with the light of justice. Decorate it with the finest gold leaf of good deeds. Adorn it with the walls and stones of faith and generosity. Crown it with the pinnacle of prayer. In this way you will make it a perfect dwelling place for the Lord. You will be able to receive him as in a splendid palace, and through his grace you will already possess him, his image enthroned in the temple of your spirit.

From the treatise Against Heresies by Saint Irenaeus, bishop
(Lb. 4,13-14,1: SC 100, 534-540)
The friendship of God

Our Lord, the Word of God, first drew men to God as servants, but later he freed those made subject to him. He himself testified to this: I do not call you servants any longer, for a servant does not know what his master is doing. Instead I call you friends, since I have made known to you everything that I have learned from my Father. Friendship with God brings the gift of immortality to those who accept it.

In the beginning God created Adam, not because he needed man, but because he wanted to have someone on whom to bestow his blessings. Not only before Adam but also before all creation, the Word was glorifying the Father in whom he dwelt, and was himself being glorified by the Father. The Word himself said: Father, glorify me with that glory I had with you before the world was.

Nor did the Lord need our service. He commanded us to follow him, but his was the gift of salvation. To follow the Saviour is to share in salvation; to follow the light is to enjoy the light. Those who are in the light do not illuminate the light but are themselves illuminated and enlightened by the light. They add nothing to the light; rather, they are beneficiaries, for they are enlightened by the light.

The same is true of service to God: it adds nothing to God, nor does God need the service of man. Rather, he gives life and immortality and eternal glory to those who follow and serve him. He confers a benefit on his servants in return for their service and on his followers in return for their loyalty, but he receives no benefit from them. He is rich, perfect and in need of nothing.

The reason why God requires service from man is this: because he is good and merciful he desires to confer benefits on those who persevere in his service. In proportion to God’s need of nothing is man’s need for communion with God.

This is the glory of man: to persevere and remain in the service of God. For this reason the Lord told his disciples: You did not choose me but I chose you. He meant that his disciples did not glorify him by following him, but in following the Son of God they were glorified by him. As he said: I wish that where I am they also may be, that they may see my glory.
