Isaiah 58:5Meaning & Commentary from the Church Fathers

Is this such a fast as I have chosen: for a man to afflict his soul for a day? is this it, to wind his head about like a circle, and to spread sackcloth and ashes? wilt thou call this a fast, and a day acceptable to the Lord?

John Chrysostom

4th centuryChurch Father

When you engage in judgment and disputes, you fast and afflict the lowly (Isaiah 58:4). Symmachus refers to this as 'torment.' Consider the different commands given. Fasting and chastity hold no value if the outcomes they should yield are missing. Some commandments stand alone while others depend on supplementary actions; similarly, just as agricultural efforts require seeds, cultivation, and additional resources, wrestling necessitates fists, oil, and training, so too do spiritual practices require complementary efforts.

What purpose does fasting serve? It is aimed at eradicating conflict. And where does conflict arise? It emerges when individuals surrender their minds to foolishness. Why do you fast in the manner that you do today? Why do you approach Me when I am not inclined to listen? * You, O Jew, should have fasted in times when your indulgence brought you distress, when excessive feasting spawned wickedness - that was the time for fasting, not now, as your current fast is inappropriate and detestable. Who asserts this? It is Isaiah himself, who proclaims with urgency: 'I have chosen not this fast.' Why? Because, 'in judgments and quarrels you shall fast, and you shall strike with the heels of the humble.' If your fast was deemed loathsome while you oppressed those beneath you, will it be pleasing now, when you have harmed the Lord? How can this be right? A true faster should be gentle, repentant, and humble, not consumed by rage; yet you strike those who are already subjugated like yourself.

Cyrill of Alexandria

5th centuryChurch Father

How can I observe a fast on this day in order to hear Your voice calling out? I have not chosen a fast of this nature nor a day dedicated merely to humbling the spirit of a person. It is beneath that to bow your neck like a sickle and don sackcloth and ashes, and to call it a delightful fast. The essence of genuine fasting holds great significance before God, the sovereign of all; for He graciously hears the prayers of those who revere Him. When He witnesses individuals who humble themselves through actions and sacrifices, fully divested of worldly cares, He embraces their requests; however, fasting that is approached carelessly or without effort is cast aside. We deem as holy that fasting which arises from a sincere conscience.

Anyone desiring to engage in such a fast must first valiantly distance themselves from wickedness, cleanse their soul of all impurities, eradicate the corruption of worldly desires, and cleanse their hands in innocence (Psalm 25:6). To summarize, they must demonstrate zealous commitment to every virtuous deed. Conversely, fasting that does not embody these qualities is a mere pretense and lacks the essence of authentic fasting; thus, it becomes laughable and inappropriate. Those who possess unwavering faith in their righteousness might refrain from good works, all the while mistaking futile abstention from food as a significant act in the eyes of God, yet they engage in empty gestures and exert themselves in vain. Such actions will yield no reward, as they do not please God. Therefore, why should I fast in the same manner as you on this day, merely to hear Your voice raised in lament? The term "cry" may refer to prayers associated with unproductive, I assert, fasting, or it could stem from genuine actions; for it has been said that our actions resonate with God, similar to how it was conveyed to Cain: "the voice of your brother’s blood cries out to me from the earth" (Gen. 4:10). Therefore, I did not opt for a fast of this sort; the true nature of this fast was previously defined: "In the days of your fasting you shall find your own desires, and all your labor shall be maintained; in disputes and conflicts you shall fast, while you strike the heels of the humble." Thus, if you bow your appearance like a sickle and cover yourself with ashes, that is, even if you achieve the utmost humility and undertake significant efforts, but remain burdened with intolerable vices, you will still consider such a fast to be enjoyable; for, He notes, if you are truthful, you yourselves would not deem such a fast to be pleasant.

Athanasius the Great

4th centuryChurch Father

Humility and Fasting The Word spoke against the children of Israel regarding their manner of fasting, urging them through the prophet Isaiah, saying, 'This is not the fast nor the day that I have chosen, that a man should humble his soul' (cf. Is 58:4-5). To clarify what our demeanor should be during fasting and the true essence of the fast, we must listen to God’s instructions to Moses: 'On the ninth day of this seventh month, the day of purification, let you have a holy convocation; humble your souls, and offer a sacrifice to the Lord' (Lev 23:27). Further emphasizing the seriousness of this command, He adds, 'Every soul that shall not humble itself shall be destroyed from among the people' (Lev 23:39).

Jerome of Stridon

4th centuryChurch Father

They earnestly seek Me daily and wish to understand My ways, as a community that has performed righteousness and has not abandoned the judgment of their God. The Septuagint conveys a similar message, referring specifically to the Jewish people who hurry to the synagogue and engage with the law of God, eager to learn about the actions of Abraham, Isaac, Jacob, and other saints. By clearly opening the sacred texts of the prophets and Moses, they recite the divine commandments that aptly apply to the Jews. As it is written, "the wicked shall seek Me, and shall not find Me." For it is stated, "Whosoever seeketh shall find" (Matt. 7:8), and those who do not find shall be found guilty of having sought poorly; the Lord reveals Himself to those who seek Him with goodness and sincerity.

Therefore, having turned away from the righteousness and judgment of God—which are titles attributed to Christ, as the Psalmist proclaims, "O God, give Thy judgment to the King, and Thy righteousness to the Son of the King" (Psalm 71:1)—they boast foolishly in their knowledge of the law. Meanwhile, a righteous individual does not boast of understanding Scripture but of their deeds, as it is said, "The way of Thy commandments flowed when Thou enlargedst my heart" (Ps. 118:32).

*****

They ask Me about judgments of righteousness and long to draw near to Me. They question, "Why did we fast, and You did not notice; why did we humble our souls, and You did not respond?" Behold, on the day of your fasting, your desires will be fulfilled, yet you extort from all your debtors. You fast for strife and discord, beating your fists unjustly. According to the Septuagint: they plead for judgment and righteousness, stating, "Why have we fasted, and You have not perceived? We have humbled our souls, and You have not known." For on the days of your fasts, your desires are granted, and you exhaust those under your authority, fasting for conflicts and beating the meek. Another folly exists among the Jews, as if they possessed confidence in a clear conscience—they demand righteous judgment and echo the words of the saints, saying: "Judge me, O Lord, for I am not evil in my walk" (Psalm 23:1), and again: "Try me, O Lord, and test me; kindle my womb and my heart" (Psalm 23:2). In another passage: "Judge my trial, and deliver me" (Psalms 118:154). They strive to come near to God, yet such proximity is not about location, but rather disposition; it is not about empty contemplation but requires diligent action. Hence, the Scripture instructs us about what it means to draw near to God: "Seek the Lord. And when He draweth nigh unto you, let the wicked forsake his ways, and the lawless man his thoughts." The Lord is close to those who approach Him, to them who act righteously according to the truth and can proclaim, "It is good for me to cleave unto God" (Psalm 72:28). For if the Almighty God is the Father of truth and righteousness, then those who are false and unrighteous cannot draw near Him, of whom it is declared, "Neither shall the wicked sit down to Thee, nor shall the unrighteous abide before Thy eyes" (Psalm 5:6). They challenge, "Why have we fasted, and You have not seen; we have humbled our souls, and You have not known?" They accuse the Lord of injustice, claiming He overlooks their good deeds, while presenting to God a mere need for sustenance, devoid of virtues, neglecting the true nourishment designed for the faithful who recognize the truth, and instead pursuing the warnings of Proverbs: "These feed on the food of wickedness, but they are drunk with the wine of transgression" (Proverbs 4:17). The Pharisee who feasted on such fare boasted of his fasting twice a week (Luke 18), though he drank not from the vineyard of Sorek but from the vineyard of Sodom, whose wine is the fury of dragons and the poisonous clusters of bitterness (Deuteronomy 32). God rebukes them through the prophet: "The sins of My people are consuming them" (Hosea 4:8). Furthermore, "Wherefore wickedness hath prevailed, and unrighteousness hath enlarged; the fruit of falsehood hath come to an end" (Hosea 10:13). As they posed the question to God, desiring the reason for their fasting and humility without response from Him, they overlooked the ancient account of why He did not regard the offerings of Cain, who, though he brought gifts properly, failed to share rightly with his brother (Genesis 4). Ignoring the commandment to "love the Lord thy God with all thy heart, and with all thy soul, and with all thy might" (Matthew 22:37; Matthew 22:39), they forgot that God is not dismissive of fasting but of the behaviors enacted during those fasts, asserting, "In the days of your fasts your desires are fulfilled," indicating that you fulfill not God's wishes but your own, as Paul cautions in his letter to the Ephesians: "According to the prince of the power of the air, the spirit that now works in the children of disobedience; among whom we all once lived in the desires of our flesh, doing the will of the flesh and of the mind, and were by nature children of wrath, even as the others" (Eph. 2:2-3). The expression in the Seventy referring to extorting from creditors is better rendered by Theodotion and Symmachus, whose interpretations we adopt here, stating you take advantage of your debtors. This demonstrates the danger of exploiting a poor individual who cannot repay, as well as the objection of seizing a garment from a cold debtor, lest their voice reach God. For he who shows mercy to the poor lends to God (Proverbs 19:17), whereas he who extorts the needy inflicts harm upon God. Assuredly, the text implies the same, leading us to the subsequent passage: "Loose the bonds of wickedness, untie the cords of the oppressed." This likely references unjust claims. For what benefit is there in appearing pale from fasting, or fasting for quarrels and conflict, as stated: "He who loves sin rejoices in strife" (Proverbs 17). The servant of the Lord ought not to quarrel but should exemplify gentleness (2 Tim. 2), imitating Him who teaches, "Learn from Me, for I am gentle and lowly in heart" (Matt. 11:29), ensuring that humility is genuine and seeks not the accolades of men but the awareness within one’s own soul. Yet alas, they fast and strike down the humble with their fists, thus denying them dignity. Hence, a bishop must not be a striker (1 Tim. 2:3). For how can he who cannot control his hands or speech restrain his passions? This is the sort of fasting the Lord reproaches at the outset of this prophet, declaring: "My soul hates fasting and idleness, new moons and Sabbaths and your other feasts" (Isaiah 1:13-14). Thus, it is commanded through Joel, "Sanctify the fast, proclaim a holy assembly" (Joel 2:15), so we may turn from sin and sanctify our fasts through good works and heal the wounds of sin. Consequently, it is further stated, "Let the bridegroom go forth from his chamber, and the bride from her bridal room" (Joel 2:16), calling for a focus on prayer during the fast, that our inward selves may not consume the flesh of the dragon given as food to the nations of Ethiopia. We do not assert this to discourage fasting, for through fasting, Daniel, the beloved of God, learned what was to come (Dan. 9), and the Ninevites turned away God’s wrath (John 3), and Elijah (3 Kings 19) and Moses (Ex. 34), during their forty days of fasting, received divine love, just as the Lord Himself (Mt. 4) fasted for that same duration, establishing annual days of fasting. It is futile to have an empty belly while simultaneously engaging in actions displeasing to God; to wear a disfigured face merely to appear fasting before others; for such individuals will be excluded from the kingdom of God, having already received their reward (Matt. 6). In light of this, the Apostle emphasizes that even if one were to sacrifice their body to be burnt or glorified (as both are possible), without the love of God that resides in the heart, such acts of devotion would amount to nothing.

"Do not fast as you do today, that your voice may be elevated on high. Is this the kind of fasting I have chosen—wearing out one's soul all day, bowing down one's head like a bulrush, and covering oneself with sackcloth and ashes? Is this the fasting I desire and the acceptable day of the Lord?" The Septuagint states: "Why do you fast for Me, as you do now, that your voice may be heard crying? Not such a fast have I chosen, nor such a day to humble your soul. And not such a one if you bend your neck in a circle or cover yourself with rags and ashes will you call an acceptable fast." To prevent them from dismissing the fasting He has commanded, He instructs on the proper manner of fasting, warning what to avoid. Thus, concerning your cries being heard on high, do not shout when you pray, nor pray in the synagogues or at the street corners to make yourself visible to men (Matt. 6), nor lift your voice excessively, like the Pharisee rejected in God's eyes; do not parade your appearance and deeds (Luke 18). Therefore, the Lord, in distancing Himself from the prayers of Pharisees, teaches the disciples the proper approach to prayer (Matt. 6): let them conceal their inner thoughts and speak privately to God, who listens to the silence of the heart; let them cry out internally, "Abba, Father" (Rom. 8:15), and rather than distorting their faces in somberness, wash and anoint themselves with oil. The Evangelist John reflects this: "And you also have an anointing from the Holy One" (1 John 2:20), by which, when they are anointed, they themselves become holy. For God desires not merely exhaustion and internal humility at the expense of the body, bending it shapeless, lowering the neck, and trudging about morose, as reflected in the Psalms: "I have suffered and slumbered to the end; I have walked all day long in sorrow" (Psalm 37:7). No one should don ragged clothing or sleep in ashes, as we read concerning David and Ahab (2 Sam. 3; 3 Sam. 21), but let him pursue what follows. The Apostle mentions often fasting (2 Cor. 6; 2 Cor. 11), and the Lord teaches that when the Bridegroom is taken from the disciples, they will fast (Mk. 2), whereas the penitent declares in the Psalms, "I will eat ashes like bread, and my drink will be mingled with weeping" (Ps. 101:10). When they neglected me, I was veiled (Psalm 34:13). From these verses, we learn that we should prioritize pleasing the Lord and not neglect other duties.

Bodily fasting and spiritual fasting are both important aspects of our faith. Bodily fasting entails refraining from food and drink, while spiritual fasting involves abstaining from immoral thoughts, actions, and words. A true practitioner of fasting is one who steers clear of fornication, adultery, and all forms of impurity. Those who avoid anger, resentment, and revenge exemplify genuine fasting. A remarkable individual is he who exercises restraint over his speech, avoiding idle chatter, profanity, foolishness, slander, harsh judgment, falsehoods, and all forms of harmful language. A virtuous faster also keeps his hands from theft, deceit, and coveting the possessions of others. Ultimately, a true faster is one who distances himself from all evil.

Fasting is fundamentally a mental discipline. While bodily fasting aids in subduing our desires, mental fasting is essential, as physical fasting alone lacks value without it. Numerous individuals may refrain from food and drink yet fail to purify their minds of wicked thoughts, actions, and words—what benefit is that to them? Many might fast for a day or longer but do not renounce anger and revenge. Others may avoid wine, meat, or fish yet use their tongues to harm others—what good is that? Some may avoid touching food but engage in corruption and theft—what value is that?

True fasting is defined by the abstention from all forms of evil. If you wish for fasting to be fruitful for you, then engage in both bodily and spiritual fasting continuously. As you fast with your body, also fast from evil thoughts and desires. Let your mind refrain from futile thoughts. Let your memory abstain from spite. Let your will resist harmful inclinations. Ensure your eyes turn away from wicked sights: “Turn away your eyes, that you may not see vanity” (Psalm 118:37). Let your ears be deafened to vile songs and slanderous whispers. Restrain your tongue from gossip, judgment, blasphemy, lies, flattery, profanity, and all harmful and worthless speech. Keep your hands from violence and theft. Avoid walking in paths of evil: “Turn away from evil and do good” (Psalm 33:15; 1 Peter 3:11). This is the fasting that God desires from us.

Repent, and by avoiding all forms of wickedness, strive to learn virtue, and you will perpetually fast before God. “If you fast for quarrels and conflicts, and strike the soul of the humble, why do you fast as you do now, so that your voice may be heard? This is not the fast I have chosen, nor is it the day for a man to afflict his soul, to bow his head like a bulrush and lay under sackcloth and ashes. This is not the fast to call a day of delight, nor is this the fast I have chosen,” says the Lord.

Instead, release every unjust bond, eliminate all debts acquired by oppression, set free those who are bound, abolish all unjust records, share your bread with the hungry, and bring the homeless into your home. When you see someone naked, cover them, and do not hide from your fellow man. Then your light will break forth like the dawn, and your healing will quickly appear; your righteousness will go before you, and the glory of the Lord will be your rear guard. You will call out, and the Lord will respond; you will cry out, and He will say, “Here am I!” When you remove the burdens from among you, cease pointing fingers and speaking maliciously, when you offer your soul to the hungry and satisfy the afflicted: then your light will rise in the darkness, and your gloom will be like the midday sun” (Isaiah 58:4-10).

Nicephoros (Theotokis)

18th centuryCommentator

Those who fervently pursue fasting should exercise great self-awareness, for it is precisely these individuals upon whom the adversary unleashes his harmful arrows, seeking to wound their spirits and render their efforts in fasting ineffective. He injects thoughts of distraction into their minds, suggesting that relying solely on their fasting without attending to other virtues is sufficient. We often observe those who fast falling into grievous sins that undermine the rewards of their abstinence. One individual may profess faith yet harbor animosity and injustice towards a brother. Another may believe but fails to control his wrath, resorting to slander and insults against someone unable to defend themselves. Can such a fast find favor with God?

"I have chosen no fast of this kind," declares the Lord. It is not merely the act of abstaining from food that matters; one who engages in this while simultaneously causing harm to others has a meager spirit but a heart full of hardness. "I have chosen not this fast," proclaims the Lord. If your fasting resembles this—where even if you bow your neck like a sickle or lay upon coarse rags and ashes, your efforts will be rejected by God: "If you bend your neck like a sickle and lay rags and ashes on your bed, it is in vain that you call your fasting pleasant," states God through Isaiah. Another abstains from oil and wine but fails to pay the wages owed to laborers and inflicts suffering upon the vulnerable. Another refrains from food and drink until sunset, yet fills the hours with judgments, gossip, and profanity; though his stomach is empty, his mind is teeming with wicked thoughts: "I have chosen not this fast," says the Lord. How wretched is the state of those who engage in such fasting! He who abstains may either disregard God's commandment or fear becoming lax, yet still fulfills his bodily desires. However, one who fasts without regard for other divine principles does not truly honor the essence of fasting.

Vissarion (Nechaev)

19th centuryCommentator

Fasting is an act that is pleasing to God, as indicated by the Lord through the prophet Joel, who instructed the people of Israel to engage in fasting for His atonement during times of communal distress (Joel 1:14; Joel 2:12). The essence of fasting goes beyond merely humbling the spirit, inducing a sorrowful disposition, or enduring hunger as a form of self-denial. It is not sufficient to show grief or a longing for Divine assistance through outward manifestations such as bowing the head or donning sackcloth and ashes. Equally important is the necessity of maintaining harmonious relationships with our neighbors during the act of fasting. Without reconciliation with those around us, our fasting cannot truly bring us closer to God; therefore, a fast devoid of peace cannot be considered acceptable in His sight.
