Fasting in Lent: A Guide

What follows is a guide for God’s people at All Saints, and for others who might find it useful.

This post is part of a new “Why We Do What We Do” series, explaining the biblical and historic practices of the Church.

For many centuries, Christians have observed Lent as a season of repentance, prayer, and renewal. One of the ancient practices associated with this season is fasting. In recent years, All Saints has been recovering this discipline—not as a burden, but as a gift. As we approach Lent, it is helpful to consider what fasting is, why Christians have practiced it, and how it may be undertaken faithfully in the freedom of the Gospel.

The Scriptural Foundation

Fasting appears throughout Holy Scripture. Moses fasted on Mount Sinai (Exodus 34). David fasted in repentance (Psalm 35). The prophet Joel called Israel to “return to the Lord” with fasting (Joel 2:12). Our Lord Jesus Himself fasted for forty days in the wilderness (Matthew 4), and He assumed that His disciples would fast: “When you fast…” (Matthew 6:16), not “if.”

In the Book of Acts, the early Church fasted in times of prayer and discernment (Acts 13:2–3). Fasting, then, is not a medieval invention, nor a foreign custom. It belongs to the biblical life of God’s people.

Fasting and the Gospel

As Lutheran Christians, we are careful to confess that fasting does not earn God’s favor. It does not forgive sins. It does not make us more worthy of salvation. There is only one sacrifice for sin: the atoning death of Jesus Christ on the cross. Any attempt to use fasting as payment for sin turns it into a false work and robs Christ of His glory.

For this reason, Scripture and the Confessions place no binding laws on how Christians must fast. Practices have differed across centuries and cultures. As St. Irenaeus observed long ago, “differences in fasting do not destroy the unity of faith.” We fast, not by compulsion, but in freedom.

What Is Fasting?

Fasting and abstinence are related but distinct.

To fast is to eat less—to experience hunger.

To abstain is to refrain from certain foods, such as meat or rich foods.

The traditional fast of the Western Church was 1/4 meal for breakfast and lunch and a simple evening meal. Abstinence—especially from meat—was commonly practiced on Fridays.

The specific form of fasting may vary according to health, age, vocation, and circumstance. The goal is not to imitate a particular rule, but to practice moderation and self-discipline before God.

Why Do We Fast?

Our Small Catechism teaches that bodily discipline is “a fine outward training.” Fasting trains the Christian body and soul.

First, fasting teaches self-control. St. Paul writes that he disciplines his body lest he become disqualified (1 Corinthians 9:27). In a culture of constant indulgence, fasting reminds us that we are not slaves to appetite. Second, fasting deepens repentance. Hunger humbles us. It reminds us of our weakness and our dependence on God’s mercy. Third, fasting strengthens prayer. When we deny ourselves food, we become more attentive to our need for God. Physical hunger points us to a deeper hunger: “My soul thirsts for God” (Psalm 42:2). Fourth, fasting cultivates compassion. Going hungry in small measure unites us with those who lack daily bread. What we save through simpler living can be given to those in need.

Fasting, Prayer, and Almsgiving

Traditionally, fasting has never stood alone. It belongs with prayer and almsgiving—the three classic Lenten disciplines. By eating less, we often gain more time for prayer and Scripture. By spending less on food, we gain more resources for charity. Thus Lent becomes not a season of grim self-denial, but of renewed devotion and generosity.

How Might We Practice Fasting?

Each Christian should approach fasting thoughtfully and prayerfully. Some possibilities include:

• Eating smaller or simpler meals during Lent

• Abstaining from meat on Fridays

• Giving up rich foods, snacks, or alcohol

• Observing partial fasts on certain days

• Limiting eating between meals

Those with medical needs, demanding vocations, or other limitations should not burden their consciences. God desires mercy, not harm.

Begin modestly. Choose a discipline that is realistic. Pair it with prayer.

The True Purpose

Fasting is not about self-improvement. It is about re-centering our lives on Christ. By loosening our grip on earthly comforts, we learn again that “man does not live by bread alone, but by every word that proceeds from the mouth of God” (Matthew 4:4).

In the freedom of the Gospel, we discipline our flesh, strengthen our faith, and prepare our hearts to walk with Christ to the cross—and then to rejoice in His resurrection. May this coming Lenten season be for us a joyful time of repentance, renewal, and deeper trust in our gracious Lord.

Tues., May 27: Downtown Rogation Procession

A local, urban take on an ancient Christian tradition.

An “Urban Rogation Procession” for the entire Jonesboro community will be held Tuesday, May 27, beginning at 6:00pm, in downtown Jonesboro. The procession will begin in front of the Municipal Center (300 S Church St) and will continue through downtown, giving thanks to God for His blessings and asking for His continued blessing and care upon: hospitals and healthcare workers, the homeless and neglected, the unemployed, children and schools, commerce and industry, agriculture and the arts, and our city.

What are Rogation Days and what is an “Urban Rogation Procession”?

Very quickly after Jesus’ ascension into heaven on the fortieth day after Easter and His sending of the Holy Spirit at Pentecost, a Church calendar began to take form. Christians wanted to organize their lives around the life of Jesus, and so they began to observe annually days like Christmas (to celebrate Jesus’ birth), Epiphany (to celebrate the visit of the Magi to the infant Christ), Good Friday (to commemorate and give thanks for His crucifixion for our sins), Easter (to celebrate Jesus’ victory over sin and death in the resurrection), and so on. 

Quickly, days were also added to the calendar to commemorate other people and events that were especially important in the Church’s life—like the days on which various apostles were martyred, the Annunciation to the Blessed Virgin Mary, and others—including days dedicated to repentance and prayer. The Rogation Days fall into that final category.

For about fifteen hundred years now, these days of repentance and prayer have been historically observed on the Monday, Tuesday and Wednesday before the Feast of the Ascension of our Lord.  The name “Rogation” is derived from the Latin rogare, which means “to ask” or “to pray.”

According to tradition, Rogation Days were introduced into the Church’s calendar about the year 470 by Saint Mamertus, Bishop of Vienna, when the ripening crops were threatened by a volcano. Following that example, the primary focus of the Rogation Days has been that of asking for God’s blessings upon the fruits of the earth. Throughout most of history and around the world, there have been processions to fields and gardens on these days each spring, giving thanks to God for the ways He provides for our body and life and asking that He would bless the crops and give a bountiful harvest. 

Particularly in a modern urban context, many of the ways which God uses to bless us and take care of us in our bodies goes beyond just a successful crop of food. The “Urban Rogation Procession” is being held to thank God and pray for His blessing also upon the other ways He cares for our body and life in society, like the ways listed above. We will also pray for peace in the world, and many of the same prayers that were used in the first Rogation procession all the way back in the year 470 will also be prayed.
