Is Fasting for Today?

Is Fasting for Today?


The subject of spiritual disciplines comes and goes as a popular topic for Christian authors and teachers. When in vogue, most listings of spiritual disciplines include fasting as one of the desired if not essential practices. Whether in a corporate setting, be it church wide or national, or for individuals, fasting is often touted as a gateway to God’s blessing, a key to determining courses of actions, or a hallmark of spiritual sensitivity and intimacy with God.

Over the years, when I have questioned whether fasting is a spiritual discipline and whether it is to be practiced by today’s Christian, I have normally been met with incredulity. After all, doesn’t everyone know that mature Christians engage in fasting for some purpose? Nonetheless, it is beneficial to explore whether there exists a biblical warrant for the practice of  intentional fasting today.

The terms for fasting occur frequently in both the Old and New Testaments. The basic word for fast in the Old Testament simply refers to abstaining from food. There are five separate terms in the family of words for fasting in the New Testament. The reference is also to abstaining from food.1

I. Observations

An analysis of the various biblical mentions of fasting, including some where the word “fast” is not used, yields a few observations:

Fasting is the abstinence from food for specified length of time (for instance, 1 day, 7 days, 40 days). It is typically voluntary but it can be involuntary (Paul and ship’s crew Acts 27:21,33; Paul in 2 Corinthians 6:5, 11:27; probably also Jesus’ 40 day fast in conjunction with his temptation - Matthew 4, Luke 4, Mark 1).

Fasting was practiced corporately or individually.

In essence, voluntary fasting is self denial.  As such, could refraining from anything be considered fasting? In a general sense, yes. However, all Biblical instances of fasting are of food and drink. Refraining from sex in 1 Corinthians 7:5, 1 Samuel 21:4-5; or Exodus 19:15 are not instances of fasting per se.

In Israel, official national fasts were mourning over national calamities or sin.

In Israel, only the annual fast in conjunction with the Day of Atonement was required. This took place on the 10th day of the 7th month when the high priest sprinkled sacrificial blood on the ark of the covenant (Leviticus 16:29 and Acts 27:9).

Other official national holiday fasts in Israel are declared but not divinely commanded.

Fast of 4th month remembering when Nebuchadnezzar captured Jerusalem (Jeremiah 39:52; Zechariah 8:19).

Fast of 5th month remembering when Jerusalem was destroyed (Zechariah 7:3,4; 8:19).

Fast of 7th month remembering when Gedaliah was murdered (Jeremiah 41:1; 2 Kings 25:25; Zechariah 8:19).

Fast of 10th month remembering when Nebuchadnezzar seized Jerusalem (2 Kings 25; Zechariah 8:19)

Other fasts were practiced in connection with a variety of circumstances or purposes.

Entreaty for divine help or intervention or some divine action - Jehoshaphat in 2 Chronicles 20:3; Ezra in Ezra 8:21; Daniel in Daniel 1:8-21,10:3; David in 2 Samuel 12:13-23 and Psalms; Nineveh in Jonah 3:5

In connection with worship - Anna in Luke 2:36-38

Mourning over death - 1 Samuel 31:13; 2 Samuel 1:12

Making decisions or anticipating certain actions - Esther in Esther 4:16, Nehemiah in Nehemiah 1:4; Israel in Judges 20:26; the early church in Acts 13:1-13, 14:23

Most commonly, fasting was practiced in response to sin and its consequences (1 Kings 21:27; 1 Samuel 7:6; Nehemiah 1:4; 9:1; Daniel 9:3; et al.

Fasting could become an empty religious ritual -  God’s people - Isaiah 58:3-6; Jeremiah 14:12; 1 Kings 21:9-27;  Pharisees (Thursday and Monday) - Luke 18;12; the disciples of John seem to be lumped in with the Pharisees - Matthew 9:14-15, Mark 2:18-19; Luke 5:33-35.

Apparently Jesus and His disciples did not fast. If they did, no instance is recorded in Scripture. In contrast, they were questioned about their lack of fasting (Matthew 9:14; Mark 2:18; Luke 5:33) and were accused of gluttony and drunkenness (Matthew 11:19).

 Fasting was often associated with external phenomena such as dressing in sackcloth, ashes, weeping, prostration, an assembly, or typically prayer.

Fasting is not presented as a means to enhance personal spirituality or become more intimate with God. Nor is it suggested as a solution to health and diet issues.

Early history of Christin fasting

Asceticism (renunciation of the pleasures of the flesh in order to enhance the life of the spirit), including fasting, was sometimes prevalent among early Christians during the transition period from Jewish customs and legalism.

The “Teaching of the Twelve”. This document discovered in 1883 is thought to have been written in the late second century AD. It contains a whole chapter devoted to directions concerning fasting and prayer. Fasting was to take place on Wednesday and Friday and the Lord’s prayer was to be recited three times per day.

The Montanists practiced fasting. Montanus, who lived from 135-160 AD, claimed to have special divine revelation. He advocated outward religious observances including fasting. This sect was the forerunner to ascetic Christianity that arose in the fourth century AD.

Teaching of Jesus

Matthew 6:16-18

NAU  Matthew 6:16 "Whenever you fast, do not put on a gloomy face as the hypocrites do, for they neglect their appearance so that they will be noticed by men when they are fasting. Truly I say to you, they have their reward in full. 17 "But you, when you fast, anoint your head and wash your face 18 so that your fasting will not be noticed by men, but by your Father who is in secret; and your Father who sees what is done in secret will reward you.”

Fasting seems to be permitted in Matthew 6. The author uses the same phrase “whenever (Ὅταν) you…” regarding giving to the poor vs 2, praying vs 5, and fasting vs 16. While “when you are praying” vs 7 and “when you fast” vs 17 are both present participles.

 “Whenever you fast” of vs 16 (νηστεύητε) is a subjunctive indicating the possibility of fasting - “but if you are fasting and you probably are” (see Machen para 283-88). It is almost like a third class condition of probability. It is followed by the present participle “while fasting” in v 17.

Jesus does not forbid fasting nor does he require it. Rather he says that if a person chooses to fast he/she must do so privately without alerting others of his/her practice.

So, Jesus assumes that his followers might voluntarily fast. However, he admonishes them to avoid fasting with wrong motives like some of their contemporaries were doing. Apparently many were fasting privately but then appearing publicly with the trampings of fasting so others would know they had been fasting. If fasting is advertised then the practice is undoubtedly false piety rather than genuine spirituality. The motive is likely self promotion. Thus, Jesus calls these people hypocrites. The empty ritual described in Isaiah 58 comes to mind when reading Jesus’ sermon.

Matthew 9:14-15 (Mark 2:18-20; Luke 5:33-35)

NAU  Matthew 9:14 Then the disciples of John came to Him, asking, "Why do we and the Pharisees fast, but Your disciples do not fast?" 15 And Jesus said to them, "The attendants of the bridegroom cannot mourn as long as the bridegroom is with them, can they? But the days will come when the bridegroom is taken away from them, and then they will fast.

Jesus and his disciples were feasting at Matthew’s house while John the Baptist’s disciples were fasting. Thus, John’s disciples pose the “why” question to Jesus.  

“Attendants of the bridegroom” refer to either those who assist the bridegroom in wedding preparation and arrangements, or to the guests at the wedding ( as ESV and NIV). This wedding language probably had pointed significance to the disciples of John the Baptist in that John apparently referred to himself as the “friend of the Bridegroom” (John 3:28-29).

In Jesus answer to John’s disciples he connects, if not equates, fasting with mourning. This fits the general tenor of the practice among the Jews.

Jesus says that there is no need for those close to Jesus (attendants or guests) to mourn while Jesus, the Bridegroom, is present. Rather, feasting or joy is appropriate.

The “days will come when the bridegroom is taken away from them” likely refers to the cross and the initiation of the new covenant era. At the time of His crucifixion fasting would have been expected as a normal reaction by Christ’s followers.

Matthew 6 and 9 might be harmonized as follows: In 6:16-18 Jesus assumes his followers might wish to fast and admonishes them to do it properly. In 9:14-15 Jesus acknowledges that his followers are not currently fasting but that they might fast following his departure. So, chapter 6 looks to the future time when his followers might fast and chapter 9 identifies that time as the initiation of the new covenant.


Remember the question at hand is whether or not today’s Christian should practice intentional  fasting for religious purposes. Fasting for non-religious reasons is not part of the discussion.

Jesus did expect that his followers might fast (Matthew 9). Why? Because they would be sorrowful and frustrated that he was no longer with them. As an expression of mourning because of his departure some of his followers might engage in fasting.

However, does this imply that life in the new covenant era is primarily one of mourning rather than joy? I think not. Indeed, Jesus’ presence was an occasion for joy (see John 3 above). Yet, the resurrection, appearances, ascension, prospect of His return, and giving of the Holy Spirit were also reasons for joy. The new covenant itself was grand and glorious news (Hebrews 8-10). Christians do not mourn Christ’s ascension and present session; they rather rejoice with great anticipation of what is to come.

What do we make of this? Perhaps we are informed by the following observations.

Jesus does not command fasting nor does He even recommend it.

The early church initially fasted in conjunction with major actions (Acts 13 and 14). However, fasting is not mentioned in connection with other subsequent actions, not even in conjunction with the critical decision regarding the core and practice of Christianity as related to Jewish rituals as recorded in Acts 15. Apparently fasting ceased to be part of Christian religious practice.  

None of the letters to the churches even mention intentional fasting. Significantly, it is not mentioned in connection with spiritual warfare in Ephesians 6. Nor is it connected with life in the Spirit in Galatians 5.

The pastoral epistles direct and advise church leaders to engage in many practices and refrain from others, but fasting isn’t one of them.

Unlike praying, Christ followers are never admonished to fast nor are they rebuked for not fasting

Fasting is not described as an element of spiritual discipline nor as a means to get closer to God nor as a way to get time or money to engage in ministry.

It appears that fasting was specially connected with the old covenant. However, when the observance of the Day of Atonement ended, the requirement to fast ended.

On the other hand, the new covenant era is a time of great anticipation and joy. Fasting as an expected religious practice or personal spiritual discipline seems out of place.

Thus, fasting is not required or even expected as a part of corporate church life or individual spiritual life. Intentional fasting will not be a public religious practice of Christianity. Instead, some individual Christians might fast voluntarily but privately. And fasting will not be required nor viewed as a mark of spirituality nor a spiritual discipline. In fact, at best, individual intentional private fasting for spiritual purposes will be the exception not the norm.

Fasting was primarily associated with mourning. Intentional fasting was part of the old covenant religious practices but not part of the new covenant religious practices. Involuntary or unintentional fasting obviously occurs in both old and new eras.2

Jesus’ teaching and practice could be understood as follows:

The Jews prior to Jesus and in his day practiced religious fasting under the old covenant scheme. In Jesus’ day, his followers did not fast because Jesus was with them; his presence was a reason for joy or feasting, not fasting. However, when Jesus was crucified his followers might fast because his absence was a cause of mourning. But following Jesus resurrection, his presence was a cause for joy and thus fasting was not expected. Then following his ascension during the current era, even though Jesus is not physically present, the Holy Spirit is. Because this is great cause for joy, fasting is out of place. Throughout all of this but especially in the new covenant era, intentional individual fasting is not required nor is it forbidden but must be done with the right motive and must remain private. And public or corporate fasting is not part of the religious practice of Christians.

2  Pastor Dennis Clark cites an intriguing possibility regarding fasting by today’s Christian. He suggests that fasting happens for Christians today unintentionally rather than intentionally. For instance, when deeply engaged in study or prayer or ministry, sometimes a Christian basically forgets to eat or eating becomes unimportant resulting in a missed meal or two.
