Do Christians Really "Fast" During Lent?

Jesus is tempted to make bread while fasting

The other day on Facebook I got a question from a friend about my article on the 40 days of Lent. It is a good question, especially if you have the religious background both of us do, wherein we once attempted to celebrate the holy days God gave ancient Israel. Long story; maybe I'll tell it one day. But in the Old Testament you'll notice, fasting could sometimes be quite rigorous. So why do members of the Christian Movement call the somewhat gentler thing we do during Lent "fasting?"

Well, at one time the Lenten fast was much more rigorous too! But I didn't get into that. Here is the question and a modified version of my response.

______________________

Q: How do you define fasting? My understanding of it is that it's literally going without any food or water for a period of 24 hours.

I remember many years ago a minister... mentioning in a sermon (on the Day of Atonement) that he never knew of anyone who tried to fast this way for 40 days that didn't end up doing permanent damage to his/her body, and thus strictly warned against attempting it in this day and age, due to the degeneration of the human body.

But your article makes it sound as if it's a relatively common thing for folks to do.

What am I missing here?


A: As you point out there would be a lot of dead and sickly worshipers each year if it was a full on fast. This Scientific American article says it's just barely possible to to go without food for 40 days or a little longer, but if you also don't drink anything you'll be dead in 2 weeks.  It seems to me that Christ, Moses -- who did it twice! -- and Elijah must have had supernatural assistance to make it that long.

We're dealing with the Christian fast of Lent of course, which is not necessarily patterned on an ancient Israelite fast. But it's not without biblical precedent, since it does resemble Daniel's 'no pleasant bread' fast in the Book of Daniel 10.3 (In the old King James Version Daniel says, "I ate no pleasant bread, neither came flesh nor wine in my mouth, neither did I anoint myself at all, till three whole weeks were fulfilled." ('Pleasant bread' means 'rich food.')

So for instance I'm eating no meat for the 40 days. Others abstain from other things.  In the Old Testament there are fasts that include not putting oil in your hair or even refusing to bathe (although Jesus said not to do that.)

At any rate, yes this type of a fast is fairly common.

The Scriptures mention different degrees and  types of fasts. In case you are really, really interested in what the Bible says about fasting (or just have a research paper on it), here is a comprehensive list of every fast it mentions.

Scriptural References to Fasting

What follows is a comprehensive list of references to fasting in Scripture, with a brief summary of the contents of each passage (synoptic passages have been treated together). Notation is made of the extent of the fast (whether the fast is strictly individual or of a corporate nature), for the purpose of highlighting the corporate nature of biblical fasting in contrast to the frequent misconception that fasting was intended to be a strictly private, individualistic matter. Some text critical notes related to questionable NT passages are made here, but a fuller discussion may be found above in the discussion in the second chapter.
