Fasting broken: when does affliction become an empty act?

Source: The prophet's cry: what is truly called a fast?

"Is this the fast I choose, a day for a person to afflict their soul? To bow their head like a reed and spread out sackcloth and ashes? Will you call this a fast, and a day of favor to the Lord?! Is this not the fast I choose - to loosen the chains of wickedness, to untie the bands of the yoke, to let the oppressed go free and to break every yoke... Is it not to share your bread with the hungry, and to bring the homeless poor into your house."

(Isaiah 58:5-7; Image: Isaiah in Michelangelo's painting, in the Sistine Chapel)

Explanation: The great upheaval: when ritual meets reality

Speaking on God's behalf, the prophet Isaiah delivers a sharp critique of formal fasting. The people of Israel fast, afflict themselves, bow their heads like a reed in the wind, put on sackcloth—and think this is what God wants. But Isaiah asks: "Is this the fast I choose?" The answer: no. The true fast is to let the oppressed go free, to share your bread with the hungry, to bring the poor into your home. The physical fast is worthless if one's actions are marked by oppression, exploitation, and ruthlessness. This is the crucial turning point: ritual acts are meant to express kindness and compassion, and without them, those acts are hollow.

Perspective: The irony of Yom Kippur: reading about the worthlessness of fasting while fasting

This is the haftarah (prophetic reading) read on Yom Kippur morning, at the very hour when every synagogue is packed with hungry people praying for forgiveness, while the prophet proclaims that fasting has no intrinsic value. And there is a certain irony in this, because this chapter was written to tell us that our fasting has no intrinsic value. Here is what Isaiah is doing: he takes the central religious act—affliction, fasting—and says, "That is not enough. In fact, that is not the point."

The problem is that fasting is easy; you can sleep for twenty-four hours and fulfill your obligation to fast. But "to loosen the chains of wickedness"? That demands confrontation, it demands taking risks—above all, confronting oneself, admitting a mistake. That is not something you can pretend to do. Isaiah said this 2,700 years ago, and perhaps in our generation we understand it better, even if we still have a long way to go.

Going Deeper: The sin that cannot be mended: when evil ripples beyond us

Maimonides, in the Laws of Repentance (2:7), writes that there are sins for which repentance is not finalized until the day of death arrives. Which sins? "One who leads the public to sin." When someone leads the public to sin, their repentance cannot undo the damage—it sets off a wave of injustice that keeps rolling forward. And this is what Isaiah is saying: a person can fast for forty days, but if they pay their worker starvation wages, exploit the widow, and turn a blind eye to the stranger's plight—the fast, even if undertaken with a sincere heart, cannot completely erase the traces of evil, until death.

Culture: Isaiah in Rome: when a prophet becomes decoration for the corruption he fought

Rome is filled with statues, most of them tied to Christianity. In Piazza Mignanelli, near the Spanish Steps, stands the Column of the Immaculate Conception, surrounded by four prophets—Moses, David, Ezekiel, and Isaiah—with the mother of Jesus above them. All five were Jewish, and all demanded doing what is right and good in their time. Standing before this magnificent column, what one must remember above all is the gulf between Christian Rome and these five Jews. The role of the four prophets at the base of the monument was to herald the coming of Jesus—ascetic, moral—yet ultimately, had Isaiah risen from his statue, he surely would have cried out at how his image and his book were used to justify wickedness, corrupt wealth, and terrible cruelty.
