Augustine of Hippo : He is finding fault, you see, with the fasts of the quarrelsome; he is looking for the fasts of the kindhearted. He is finding fault with those who oppress others; he is looking for those who give relief. He is finding fault with those who stir up strife; he is looking for those who set free. That is why, you see, during these days you restrain your desires for lawful things; it is in order not to commit unlawful things. If you refrain from your marriage rights during these days, then surely you should not drown yourself in wine or adultery on any day.In this way, in humility and charity, by fasting and giving, by restraining ourselves and forgiving, by paying out good deeds and not paying back bad ones, by turning away from evil and doing good, our prayer seeks peace and obtains it. — SERMON 206:3 Caesarius of Arles : If we carefully heed the fact that Christ hungers in the person of the poor, beloved, it will be profitable for us.… Listen and see, a coin and a kingdom. What comparison is there, beloved? You give the poor a coin and receive a kingdom from Christ; you bestow a mouthful and are given eternal life; you offer clothes, and Christ grants the forgiveness of your sins. — SERMON 25:2 Clement of Alexandria : And we shall find many examples also in other places,-as, for instance, respecting prayer: "Good works are an acceptable prayer to the Lord," says the Scripture. And the manner of prayer is described. "If thou seest," it is said, "the naked, cover him; and thou shalt not overlook those who belong to thy seed. Then shall thy light spring forth early, and thy healing shall spring up quickly; and thy righteousness shall go before thee, and the glory of God shall encompass thee." What, then, is the fruit of such prayer? "Then shall thou call, and God will hear thee; whilst thou art yet speaking, He will say, I am here." — The Instructor Book 3 Cyril of Alexandria : When you refrain from doing these things, then the things you lack will be yours. For the bearing of fruit toward the neighbor refers to the noble things of love. Love is the fulfillment of the law, as it stands written. For the fulfilling of love toward brothers and compassion are the marks of a reward with God. Seeing how to abstain from evil and doing good are not the same thing. For it does not suffice for glory with God to flee evil but to try in all ways to meet needs and do good works and hold fast to diligence in godliness … thus the old law being a schoolmaster to Christ did not introduce the fulfillment of the good for those at that time but rather taught them to restrain from evil. Thus, "do not kill, do not commit adultery, do not swear" have this force. But the perfect fulfillment of all goodness in the oracles is kept through Christ, through which we learn to fulfill those works of love toward God and our fellows. — COMMENTARY ON Isaiah 5:3.58:6-7 Jerome : Or indeed, this must be said, because it is about fasting, and fasting has affliction and humiliation of the soul: but the affliction of sinners' bodies begs for indulgence. Divine Scripture teaches us to forgive our debtors, so that the Heavenly Father may also forgive us our debts (Mark 11). The ancient history tells that in the year of the Jubilee, which is the true Jubilee, all possessions return to their owners and slaves regain their freedom, and all obligations, commonly known as cautions, become void (Leviticus 25 and 27). If this is commanded in the old Law (Exodus 21), how much more in the Gospel, where everything that is good is multiplied: and not an eye for an eye, or a tooth for a tooth is commanded, but to offer the other cheek to the one who strikes! And so that we know what we have said above: Collect all your debtors, have the creditors written down, and join them with the debtors more clearly: Forgive those who are broken, that is, those who are broken by poverty, whom affliction has afflicted, so that you do not allow them to beg. And break all burdens by which they are oppressed. For which the Seventy translated it more clearly, and cut off all unjust writing: which Symmachus translated: And break all false caution. But it could happen that someone would say, 'I have no debtors, what should I do to observe my fast?' It follows: Break your bread to the hungry. Not many loaves, nor cause poverty, but one loaf. Not the whole loaf itself, but a portion of bread: which if you did not fast, you would eat; so that your fast is not a profit for your purse, but a satisfaction for your soul. And beautifully he added 'your', so that you do not make your alms from robbery: For the redemption of a man's soul is his own treasure (Proverbs 13, 6). And in another place: Honor the Lord with your just labor (Proverbs 3, 9). Certainly if you do not have bread, and there is a great multitude of hungry people, give from what you suffer no harm. In which there are no expenses, bring the homeless, the poor without shelter, into your home. Or as it is said in Hebrew, into the house, so that if you do not have your own, you bring them into a small guesthouse, which you either rent or possess as a favor. If you see someone naked, cover him. And what the Lord said in the Gospel: Whoever has two tunics, let him give one to him who has none (Luke 3, 11). For he did not command that one be torn and divided, as many do for the sake of popular applause, but that the other not be preserved, increasing the precepts of justice, so that he also may say that having handed a cup of cold water has its rewards. And he says 'your' flesh, do not despise it. For every man is our flesh. And according to the Gospel parable, he is called the neighbor who does good to the one who came down from Jerusalem to Jericho and was wounded by robbers (Luke 10). Or certainly according to the Seventy who said: And do not despise the servants of your own seed, let us understand those servants of your own seed, about whom the Apostle also teaches, saying that alms should be done to all, but especially to the servants of faith (Galatians 6). For they are our flesh and our seed, being generated with us by the same parent. To whom the Savior also extended his hand, saying: These are my mother and my brothers, who do the will of my Father (Mark 3, 34, 35). And so that we know that there is one Lord, both of the new and the old Testament, the Lord speaks the same in the Gospel about those who will stand on the right on the day of judgment, saying: Come, you blessed of my Father, inherit the kingdom prepared for you from the foundation of the world. For I was hungry and you gave me food. I was thirsty and you gave me drink. I was sick and in prison, and you visited me. I was a stranger and you brought me into your home. And I was naked and you clothed me (Matthew 25, 34-36). And to those who humbly say that they have done nothing for the Lord and Savior, he responds: As long as you have done it to one of the least of my brothers, you have done it to me. According to tropology, we can say: Whoever fasts from all evil and wishes his fast to be respected, not only must turn away from evil, but also do good, so as to break every bond of iniquity by which simple believers are bound by the deceit of heretics. And the Prophet also speaks about the bonds of violent contracts, which he demonstrates in the psalm, saying: But those who go astray in their obligations, the Lord will bring with those who work iniquity (Psalms 125, 5). For all those who are bound by the bonds of heretics, turn away from the Lord; they are like a bull led to the slaughter; and they choose and exchange falsehood for truth. Therefore, let the Ecclesiastical man dismiss and dissolve these kinds of men, who are broken in judgment; and break and tear apart all the writings of heretics, about whom the same Prophet says: Woe to those who write iniquity: for they write malice, stealing the judgment of the poor people of mine (Isaiah 10, 1, 2), so that they do not hold every simple person ensnared by their traps. And when he does this, let him break his bread to the hungry of the Ecclesiastical doctrine, which the Lord also did, giving broken bread to the Apostles, which he left for them in seven baskets and twelve small baskets, not whole as they were in the Law, but crushed and broken in the Gospel, so that they would have something to give to the poor (Matthew 15). When you see those who do not have the warmth of faith, but who freeze outside the Church in the coldness of unbelief, bring them into the house of the Church, and cover them with the robe of incorruption; so that, clothed in Christ's tunic, they do not remain in the graves, as we read of the one who was possessed by a legion of demons, who lived naked among the memorials of the dead. And when you have done this, let your generosity be shown to all, especially to the faithful servants. — Commentary on Isaiah
