The Orthodox Church, regarding man as a unity of soul and body, has always insisted that the body must be trained and disciplined as well as the soul. "Fasting and self-control are the first virtue, the mother, the root, source, and foundation of all good."
Fasting is not a set of dietary laws or legalistic requirements. Rather, fasting accompanied by prayer, is a spiritual aid which disciplines the body and soul and enables them to strive together to bring the whole person closer to God, especially during the preparation periods of the great feastdays of the Church.

1. The day before Epiphany - January 5.
