Our Church adopted fasting from the Old Testament. Christ Himself fasted and preached about its significance (Matt. 6:16, Mark 2:20 and 9:29). The Early Church too, observed fasting (Acts 13:2, 14:23 and II Cor. 2:27). As early as the beginning of the third century, we have documents (of Didache) substantiating the early establishment of regular fast days, such as Wednesday and Friday: these two days are symbolical and commemorative of Christ’s betrayal and crucifixion. And by the end of the fourth century, the forty day (Great) Lenten fast was wide-spread. Later other fasting periods were also adopted by our Church.
Fasting, accompanied by prayer and charity, is a way of disciplining our entire person, not just the body. Contrary to what most people think, it underlines –rather than undermining- the significance of the body towards whose glory it also contributes. Furthermore fasting is a small way of sharing in contemporary suffering throughout the world.
In our ecclesiastical calendar, fasting usually precedes great feasts and acts as a preparation for these events.
