SDG here (not Jimmy) with some brief thoughts on fasting.
In recent decades, many American Evangelicals have rediscovered the practice of fasting long practiced in the Catholic and Orthodox traditions. In 1978 Richard J. Foster, a Protestant writer in the Quaker tradition, published Celebration of Discipline, a book on spiritual practices that introduced many Protestants to the ascetical and devotional heritage of the early monastic tradition, the mystical writings of John of the Cross, and other writers ranging from Brother Lawrence to Dostoyevski to Thomas Merton.
It was reading Foster as a young Evangelical that I first encountered the claim that fasting is a normative part of the Christian life: After all, Our Lord in the Sermon on the Mount said to his followers "When you fast," not "if"; and in Mark 2 Jesus declared that while His disciples could not fast while He, the Bridegroom, was among them, in the days when the Bridegroom would be taken away, "then they will fast."
Later, as I learned more about the early Fathers, I discovered the Didache, one of the earliest extrabiblical Christian texts (possibly as early as 70 AD), which records that Christians in the apostolic Church fasted twice a week, on Wednesdays and Fridays (in contradistinction to the practice of the "hypocrites," which was to fast Mondays and Thursdays).
Even so, for many Christians, fasting continues to be a somewhat exotic or unfamiliar practice, perhaps carrying a suspicious whiff of works-righteousness or something of the sort. Why do we fast? How can we explain it to others?
What follows below the fold is my attempt, originally written for and posted in a non-Catholic Christian forum, to brief sum up what I understand to be the basics regarding the place of fasting in Christian spirituality as a form of penance and asceticism. Additional thoughts, insights, corrections and comments are welcome.
