On November the 15th we began the Nativity Fast. In a way analogous to the Great Lenten Fast, we will spend six weeks avoiding certain foods—meat, dairy, fish, wine, and olive oil. But, why do we do this. Just what is this winter fast?

It is a kind of Journey in which we join the Magi, kings from the east, and follow the guiding star into an ever increasing awareness of the awesome wonder of the salvation that is provided in Christ. The discipline of the fast helps us focus on the coming of our Savior. It moves us beyond our indifference toward a vivid appreciation for the new and marvelous blessing that is Nativity. Gradually we begin to grasp the significance of our Lord’s birth, and with the angelic hosts we look

with trembling on this mystery and [are] struck with wonder: for Thou who hast adorned the vault of heaven with stars hast been well pleased to be born as a babe; and Thou who holdest all the ends of the earth in the hollow of Thy hand art laid in a manger of dumb beasts. For by such a dispensation has Thy compassion been made known, O Christ, and Thy great mercy: glory to Thee. (Sticheron of the Third Hour, Christmas Eve)

The fast then is a time of progress, a time of Preparation. As our awareness of the significance of the Nativity grows, we are afforded an opportunity to prepare ourselves to worship, to rejoice, and, above all, to thank God for His great mercy to us. Throughout the Advent season our anticipation of His coming grows, and by the time Nativity arrives we are ready to join with all of creation in joyful celebration.

Make glad, O ye righteous! Greatly rejoice, O ye heavens! Ye mountains, dance for joy! Christ is born; and like the cherubim the Virgin makes a throne, carrying at her bosom God the Word made flesh. Shepherds, glorify the newborn Child! Magi, offer the Master gifts! Angels, sing praises, saying: 'O Lord past understanding, glory to Thee!'
(First sticheron of the Praises, Nativity Matins)
