Fasting

Fasting is the voluntary going without food for a set time, undertaken as an expression of prayer, repentance, or devotion to God. In Scripture it rarely stands alone: Daniel sets his face to seek God “by prayer and petitions, with fasting and sackcloth and ashes” (Daniel 9:3), and Joel couples fasting with weeping and mourning (Joel 2:12), while the psalmist answers hostility with prayer rather than retaliation (Psalm 109:4). The texts consistently locate the meaning of the act in the inward posture rather than the outward gesture — “Tear your heart and not your garments,” Joel says, grounding that call in God’s character as “gracious and merciful, slow to anger, and abundant in loving kindness” (Joel 2:13).

Fasting in these passages is most often penitential and corporate. Joel summons a whole people to return to God with fasting (Joel 2:12); Nineveh’s fast is joined to hope rather than certainty — “Who knows whether God will not turn and relent” (Jonah 3:9) — and God “saw their works, that they turned from their evil way” and relented (Jonah 3:10). Yet the prophets also press a hard question about motive. Isaiah 58:3 records a people who fasted and complained that God did not notice; the answer given is that the fast God chooses is “to release the bonds of wickedness... to let the oppressed go free” and to feed the hungry, house the outcast, and clothe the naked (Isaiah 58:6–7). Zechariah similarly asks whether seventy years of fasting in the fifth and seventh months was done “to me, really to me” (Zechariah 7:5).

In the New Testament the practice appears in the setting of worship and decision: at Antioch, while they served the Lord and fasted, the Holy Spirit spoke and set apart Barnabas and Saul for missionary work (Acts 13:2). Paul lists “fastings often” among his labours and hardships (2 Corinthians 11:27); the Greek term there can cover going without food whether chosen or forced, so the verse may describe deprivation endured for the gospel as much as deliberate discipline.

Christian traditions read the term differently, and the differences are substantive rather than trivial. Eastern Orthodox, Roman Catholic, Anglican, and Lutheran practice has generally treated fasting as a bodily discipline and a means of grace, with set seasons and days (Lent and Good Friday being the most widely observed), while much of the Reformed and evangelical stream has held that fasting is a free practice rather than a commanded ordinance, wary of anything that looks like earning merit, and often frames it as intensified prayer or a response to crisis. Pentecostal and charismatic traditions commonly emphasize fasting as a way of seeking God’s direction and spiritual power, and liberationist readings return to Isaiah 58 to tie fasting to justice and advocacy for the oppressed. Confessional disagreement also exists over whether the prophetic critique of ritual fasting abolishes the practice or simply purifies it; Isaiah 58 itself, read closely, assumes fasts will continue and defines which kind God accepts.
