How do Christians Fast?

how do Christians fastYesterday we answered the question “Why do Christians fast?” Today we’ll take a closer look at how Christians fast.

Eating Less

Though there was no single method St. John Cassian prescribed, he did offer “a single goal: avoid overeating and the filling of our bellies.”[1] While going long periods of time without food is a common form of fasting in Scripture, for many of us it can backfire and lead to binge eating when breaking a fast.  In contrast, refusing to get seconds or putting down your fork before you’re full can be simple but powerful way to fast, and avoids the dangers of either irritability or binge eating.

Eating at Fixed Times

In Celtic monasticism, people like St. Aidan often waited until after 3:00 p.m. to eat, but then ate whatever was available in moderation. They didn’t want to eat during the hours when Christ was on the cross. How might the timing of your meals create a greater awareness for you of the events of Christ’s life?

 Eating a Disciplined Diet

Our Eastern Christian sisters and brothers abstain from meat and dairy products on most Wednesdays and Fridays during the year, and do the same throughout the entire season of Lent. Wednesdays are traditionally fasting days because they are the day on which Judas agreed to betray Jesus. Fridays are fasting days because of the crucifixion. The restricted diet helps one grow in consciousness and discipline, but doesn’t deplete one’s energy as much as a total fast.

 Eating With Your Attention on Christ

St. Ignatius of Loyola wrote that “While one is eating, it is good to imagine Christ our Lord eating in company with his apostles, and to observe how he eats, how he drinks, how he looks about, and how he converses, and then to try to imitate him. In this way, one’s mind will be occupied chiefly with the consideration of Our Lord and less with the sustenance of the body.”[2] Similarly, I know a pastor who has a large replica of Rublev’s famous Trinity Icon in his dining room. When he practices his morning devotions, he imagines sitting at the table with the Trinity. How might we eat differently if we were sitting at the table with Jesus?

Regardless of how we fast, we do it as a discipline to bring us closer to God.

The Rev. Christopher Brown moved to Pittsburgh from Colorado to pursue a master of divinity (MDiv) degree at Pittsburgh Theological Seminary. He currently serves as the coordinator of the Church Planting Initiative at the Seminary along with pursuing his master’s in sacred theology. Chris is the organizing co-pastor of The Upper Room Presbyterian Church, a church plant of the PC (U.S.A.) in Pittsburgh’s Squirrel Hill neighborhood.

Why do Christians fast?

Why do Christians fast?

Updated 02/28/17

In the Ash Wednesday Gospel reading, Jesus says “when you fast, put oil on your head and wash your face, so that your fasting may be seen not by others but by your Father who is in secret; and your Father who sees in secret will reward you” (Matt 6:17-18). Notice that Jesus doesn’t say “If you fast . . .” The implication is that Jesus’ disciples will fast. Aside from teaching his disciples to fast humbly and not call attention to themselves, Jesus does not give explicit instructions about how and when to fast. Even the why seems to be taken for granted in the Gospels. During this season of Lent, as many Christians practice some form of fasting, I think it may be helpful to consider some of the reasons why the Church has practiced fasting over the centuries.

Why do Christians fast?


We fast to learn self-control.

For starters, we do not fast because we’re dualistic, gnostic, platonic, or don’t see value in food. The creation is good, and we honor God’s intentions for the world and our bodies when we nourish our bodies appropriately. But we often are not the best judges of what is appropriate. One of the fruits of the Spirit is “self-control”—the ability to discipline one’s appetites and urges. Fasting helps produce this fruit in our lives.

For example, because the same part of our brain that controls our appetite for food also controls our sexual appetites, the monastic tradition has long recommended fasting as a remedy for lust. On a larger scale, by delaying the gratification of our appetite for food, we cultivate the sort of self-discipline that is valuable in all things (1 Pet 4:8). As Richard Foster wrote, “Our human cravings and desires are like rivers that tend to overflow their banks; fasting helps keep them in their proper channels.”[1]


We fast to think more clearly.

Our culture has a playful term for the drowsy and sluggish feeling one has after eating too much: a “food coma.” But it’s hard to pray when you’re in a food coma. Jesus invites us to practice watchfulness instead of drunkenness (Luke 21:34), and we can be more mentally alert to pray and serve when we’re not weighed down by too much food. St. John Cassian was a monk who lived in the late fourth and early fifth centuries, and whose writings influenced the famous Rule of St. Benedict. Writing about why we ought to fast, Cassian said, “It is not only too much wine that besots our mind: too much water or too much of anything makes it drowsy and stupefied.”[2]

Fasting can have the opposite effect: sharpening our thinking and making us more attentive to God and those to whom God sends us. (Many of us will respond at this point, “But I get cranky when I don’t eat!” Anger is obviously not a desired fruit of fasting, but here’s a hint: eating a low carbohydrate diet makes it easier to fast without getting irritable, because it forces your body to get used to burning fat for energy, and fat is a more stable source of energy. Try it.)

Perhaps this clarity of mind is why the disciples—“while they were worshiping the Lord and fasting”—heard the Holy Spirit calling them to send out Barnabas and Saul as missionaries in Acts 13:2-3. This means that fasting can be a powerful, but often misunderstood or overlooked element in our processes of discernment.


We fast to open ourselves up to God’s power flowing through us.

A curious thing happens when Jesus gets caught up in conversation with the Samaritan woman in John 4: He doesn’t get hungry, even though the other disciples are off searching for lunch. Jesus tells his disciples “I have food to eat that you do not know about. . . . My food is to do the will of him who sent me” (vv. 32, 34). Jesus, in his full humanity, practiced fasting as a way to live in the power of the Spirit and do the Father’s will. The inverse of this statement shows us that fasting is not a way to manipulate God. Fasting does not bend our God’s will to match our own. Rather it bends our will to match God’s. And when our will is aligned with God’s, we may discover that power greater than we imagine is at work within us (Eph 3:20).


We fast to confess our sin and brokenness.

This is most appropriate during the season of Lent, as we practice turning back to God and away from our sinful or selfish desires. Repentance gets short shrift in our proclamation of the Gospel today, but it was integral to the proclamation of Christ and the Apostles (cf. Matt 4:17, Acts 2:38, 2 Cor 7:10). To again quote Richard Foster, “More than any other Discipline, fasting reveals the things that control us.”[3] Fasting reveals the attachments we have to the world and demonstrates our desire to be attached only to Christ. To fast without an element of soul-searching and relinquishment of one’s own will is self-defeating.

All these are valid reasons to practice fasting. Maybe now you’re asking, “But how? Where do I begin?”  

We explore these questions in our next post: How do Christians fast?

Would Thomas Merton Delete His Facebook Account?

giving up facebook for Lent

Updated 02/28/17

On the first day of Lent, I expect when I open my Facebook news feed that several of my friends will post this type of status update:

“Hey y’all! I’ve decided to give up Facebook for Lent. I need to spend some quality time with my buddy JC. If you need to get ahold of me during Lent, please shot me a text, an e-mail, or a tweet.
See you in 40 days, Facebook friends!!!!!”

This status update is followed by 35 likes, and 10 comments where my friend’s Facebook friends congratulate my friend on her self-discipline, and how this fast will help her grow closer to Jesus.

Having read Thomas Merton’s New Seeds of Contemplation, these status updates make me stop and assess the validity of social media fasts as a form of detachment. There seems to be a growing movement amongst my Christian friends to equate social media usage with un-holiness. I can understand why this link exists. Facebook can be a huge time-suck. Twitter could put newspapers out of business. Instagram might be producing a generation of narcissists.

I’m not denying that excessive social media usage can make it difficult to follow Christ. My problem with Facebook fasts is that they can encourage Christians to take a certain pride in their ability to unplug, without helping them to address the overemphasis of self their attachment to social media can perpetuate.

Let me explain.

Thomas Merton, in New Seeds of Contemplation believes that a contemplative must detach themselves not just from the things of this world that distract them, but also from their very sense of self. In other words, a Facebook fast is not going to help you draw closer to God if the fast does not make you think about why your sense of self depends on having 900 Facebook friends. A Facebook fast also will not help you draw closer to God if you substitute one area of self for another, i.e giving up Facebook, but making yourself more available via text messaging, e-mail, or Twitter.

So instead of doing a Facebook fast this Lent, should we all delete our Facebook accounts?

Perhaps. For some people, the only way for them to detach themselves from their sense of self is by removing all things that distract them from God. But what if we started to envision social media not as a way for us to brag about ourselves, but as a way for us to detach from ourselves and more fully engage with each other as people of God? Instead of fasting from Facebook for 40 days, what would it look like if we committed to wishing everyone a “Happy Birthday” whose birthday fell during Lent? Or if we committed to writing one encouraging post a day on a different friend’s wall for 40 days?

If Thomas Merton were alive today, I like to imagine how he would use social media in a detached way. I picture him logging in on Sunday afternoons while sipping a hot cup of tea, gleeful with the idea of loving his scattered friends with words of encouragement, birthday wishes, and inspirational quotes.
