There are three things, my brethren, by which faith stands firm, devotion remains constant, and virtue endures. They are prayer, fasting and mercy. Prayer knocks at the door, fasting obtains, mercy receives. Prayer, mercy and fasting: these three are one, and they give life to each other.
Fasting is the soul of prayer, mercy is the lifeblood of fasting. Let no one try to separate them; they cannot be separated. If you have only one of them or not all together, you have nothing. So if you pray, fast; if you fast, show mercy; if you want your petition to be heard, hear the petition of others. If you do not close your ear to others you open God’s ear to yourself.
When you fast, see the fasting of others. If you want God to know that you are hungry, know that another is hungry. If you hope for mercy, show mercy. If you look for kindness, show kindness. If you want to receive, give. If you ask for yourself what you deny to others, your asking is a mockery.
Let this be the pattern for all men when they practise mercy: show mercy to others in the same way, with the same generosity, with the same promptness, as you want others to show mercy to you.
Therefore, let prayer, mercy and fasting be one single plea to God on our behalf, one speech in our defence, a threefold united prayer in our favour.
Let us use fasting to make up for what we have lost by despising others. Let us offer our souls in sacrifice by means of fasting. There is nothing more pleasing that we can offer to God, as the psalmist said in prophecy: A sacrifice to God is a broken spirit; God does not despise a bruised and humbled heart.
Offer your soul to God, make him an oblation of your fasting, so that your soul may be a pure offering, a holy sacrifice, a living victim, remaining your own and at the same time made over to God. Whoever fails to give this to God will not be excused, for if you are to give him yourself you are never without the means of giving.
To make these acceptable, mercy must be added. Fasting bears no fruit unless it is watered by mercy. Fasting dries up when mercy dries up. Mercy is to fasting as rain is to earth. However much you may cultivate your heart, clear the soil of your nature, root out vices, sow virtues, if you do not release the springs of mercy, your fasting will bear no fruit.
When you fast, if your mercy is thin your harvest will be thin; when you fast, what you pour out in mercy overflows into your barn. Therefore, do not lose by saving, but gather in by scattering. Give to the poor, and you give to yourself. You will not be allowed to keep what you have refused to give to others.
– From a sermon by Saint Peter Chrysologus, bishop
Are you not occupied with Christ? Why do you not talk with him? By reading the Scriptures, we listen to Christ.
– Ambrose of Milan (339-397 AD)
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.
