I have had a handful of conversations about fasting lately, coincidentally falling around the time of Lent. If you know me very well, you’ll know that this is a topic I love discussing, because of how much it transformed my life. For the last five years, fasting has also been the focus of my academic research, and I am always thinking about it.
The point of contention I always encounter with people in conversations is the issue of fasting from social media. I would like to make an apologia (defense) of fasting as strictly a physical sacrifice of food, meaning that abstaining from social media, as beneficial as this is and can be, is not true fasting. First, we will look at how fasting was historically practiced, especially in the Christian tradition. Then, we will see how in Isaiah 58, the prophet condemns the religious hypocrisy he saw in Judah at the time. Finally, we will see why the physical sacrifice of food is so central to this practice.
What is true fasting?
Practically, fasting has been practiced by both Jews and Christians for at least around two thousand years. In Jesus’ day, Jews observed two fast days per week, on Mondays and Thursdays. Later on, Christians adopted this practice, but changed their fast days to Wednesdays and Fridays. There were also certain days in the liturgical calendar during which Jews were commanded to fast (like on Purim eve, or Yom Kippur, among other days). Lent is, of course, another season marked by fasting or abstention. Typically when Christians do fast, they will spend time in the Word and in prayer when they would normally be eating.
Jesus’ Instructions for Christian Piety
In Matthew 6, Jesus gives us instructions for living a pious, or devoted life, saying, “When you pray…” When you give alms…” and “When you fast…” He contrasts the self-focused, performative ways in which people were doing these things with the better way to practice: without thought for what we gain, or how we are perceived. In modern day Evangelical practice, we tend to pray in our “prayer closets” and to give without being recognized for our generosity, although we likely wouldn’t observe fasting, regularly or otherwise.
In Eastern Orthodox tradition, which is incredibly strict around fasting, they follow Jesus’ instructions in Matthew 6 as a unified triad. They are told that on their regular fast days, whatever money they save on food should be given to the poor instead. It is a literal and direct observance of these instructions we have from Jesus, and almost surprising in its outward, community focus. We tend to think of fasting as an individual and private thing, not least of all because Jesus tells us not to broadcast that we are fasting. But our fasting is pointless if it does not in some way help me love my neighbor better, and benefit someone else other than myself.
Hypocritical Fasting
Beyond weekly fasting, in the Old Testament, sometimes it was used as a way to try and get God’s attention, to ask Him for mercy in suffering. Hannah does this in 1 Samuel 1 when she is desperate for a child, and God gives her a son in Samuel, the first prophet of Israel. David also does this in 2 Samuel 12, in an attempt to save his son’s life after conceiving illegitimately with Bathsheba. His plea is not answered in this instance. This kind of fasting is what is happening in Isaiah 58, in which God answers back to why their pleading fasts are unsuccessful. At the beginning of this chapter, God quotes the people of Judah:
“‘Why do we fast, but you do not see? Why humble ourselves, but you do not notice?’” (58:3a).
God responds by saying,
“Look, you serve your own interest on your fast day, and suppress all your workers. Look, you fast only to quarrel and fight and to strike with a wicked fist. Such fasting as you do today will not make your voice heard on high. …Will you call this a fast, a day acceptable to the Lord?” (vv. 3-4, 5b)
Following this, God corrects them by telling them they should pursue justice and to fight for the poor, oppressed, and marginalized:
“Is not this the fast that I choose: to loose the bonds of injustice, to undo the thongs 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 bring the homeless poor into your house; when you see the naked, to cover them, and not to hide yourself from your own kin?” (vv. 6-7)
The setting of this chapter takes place around the end of the 8th century or early 7th century BCE, after the nation of Israel has split in two: Israel in the north (who had already fallen to the Assyrians), and Judah in the south. Isaiah is in the Judean capital of Jerusalem, speaking to the nation of the imminent threat of invasion and destruction on the horizon. He warns them that if they do not return to God, their city will be destroyed. Of course we do know that Jerusalem did eventually fall, to the Babylonians, less than 150 years afterward, and the people of God were sent into exile.
In a manner not much different from today, the poor were being extorted and exploited in order to benefit a very few rich at the top. This is what the prophets time and again condemned, for we know this is not what God commanded for His people. He hates religious hypocrisy and performative piety. In continuation with the Old Testament prophetic tradition, just as in Matthew 6, we also see this in the words of Jesus in Matthew 9:13, where he quotes from Hosea: “I desire steadfast love and not sacrifice; the knowledge of God rather than burnt offerings.” (Hos. 6:9)
Social Media “Fasting”
Having done a brief overview of how fasting was practiced historically by both Jews and Christians on a regular basis; how improper fasting was condemned in the Old Testament; and how different Christian traditions practice fasting still today, where do we place abstention from social media?
A simple reductio ad absurdum will make the matter clear: Jesus did not have a Facebook to delete from his phone; Moses did not have Instagram to abstain from; and Paul certainly did not spend his evenings scrolling on Twitter or TikTok. I use social media daily, and I am not calling it evil. Nor am I saying that abstaining from social media for a time is hypocritical, pointless, or self-serving. While there is much benefit in decreasing our time scrolling mindlessly, I maintain it is a shortsighted way to cultivate one of those time-honored spiritual disciplines, like prayer, fasting, scripture reading, and simply sitting still in God’s presence.
As we have seen in both the Old Testament and the New, true fasting must be sacrificial, and involve abstention from food. This sacrifice is just as legitimate whether it is as small as giving up chocolate or meat, or doing a full, water-only fast for a time. The cravings or hunger of the body must be a reminder to us throughout our fast of the sacrifice we have chosen to make, and why we have chosen to do so–and that is so that we see God’s will be done and his Kingdom come!
We are called to imitate Christ in his self-sacrificial love for us, and fasting can become a highly effective way to live out a cruciform life. Through this we willingly enter into the suffering of Christ, even on some small level, for its power to transform us more and more into His image. Therefore, while abstaining from social media is a useful auxiliary to our cultivation of spiritual disciplines, we cannot call it fasting. Be encouraged, this is a doable practice that can yield much fruit, even with the smallest of sacrifices.
