From Dom Prosper Gueranger's 'The Liturgical Year':
Let us celebrate the Nativity of the Virgin Mary; let us adore her Son, Christ our Lord. Such is the invitation addressed to us today by the Church. Let us hearken to her call; let us enter into her overflowing joy. The Bridegroom is at hand, for his throne is now set up on earth; yet a little while, and he will appear in the diadem of our human nature, wherewith his Mother is to crown him on the day of the joy of his heart, and of ours. Today, as on the glorious Assumption, the sacred Canticle is heard; but this time it belongs more to earth than to heaven.
Truly a better Paradise than the first is given us at this hour. Eden, fear no more that man will endeavor to enter thee; thy Cherubim may leave the gates and return to heaven. What are thy beautiful fruits to us, since we cannot touch them without dying? Death is now for those who will not eat of the fruit so soon to appear amid the flowers of the virgin earth to which our God has led us.
Hail, new world, far surpassing in magnificence the first creation! Hail blessed haven, where we find a calm after so many storms! Aurora dawns; the rainbow glitters in the heavens; the dove comes forth; the ark rests upon the earth, offering new destinies to the world. The haven, the aurora, the rainbow, the dove, the ark of salvation, the Paradise of the heavenly Adam, the creation whereof the former was but a shadow: all this art thou, sweet infant, in whom already dwell all grace, all truth, all life.
Thou art the little cloud, which the father of prophets in the suppliant anguish of his soul awaited; and thou bringest refreshment to the parched earth. Under the weakness of thy fragile form, appears the Mother of fair love and of holy hope. Thou art that other light cloud of exquisite fragrance, which our desert sends up to heaven. In the incomparable humility of thy soul, which knows not itself, the Angels, standing like armed warriors around thy cradle, recognize their Queen.
O Tower of the true David; citadel withstanding the first shock of Satan’s attack, and breaking all his power; true Sion, founded on the holy mountains, the highest summits of virtue; temple and palace, feebly foreshadowed by those of Solomon; house built by Eternal Wisdom for herself: the faultless lines of thy fair architecture were planned from all eternity. Together with Emmanuel, who predestined thee for his home of delights, thou art thyself, O blessed child, the crowning point of creation, the divine ideal fully realized on earth.
Let us, then, understand the Church when, even on this day, she proclaims thy divine maternity, and unites in her chants of praise the birth of Emmanuel and thine own. He who, being Son of God by essence, willed to be also Son of man, had, before all other designs, decreed that he would have a Mother. Such, consequently, was the primordial, absolute character of that title of mother, that in the eternal decree, it was one with the very being of the chosen creature, the motive and cause of her existence, as well as the source of all her perfections natural and supernatural. We too, then, must recognize thee as Mother, even from thy very cradle, and must celebrate thy birthday by adoring thy Son our Lord.

When princes are born, we prognosticate their future greatness by recalling the glory of their ancestors. The Church does in like manner today. The Gospel will recount the temporal genealogy of Messias, which is also the genealogy of her, who was born for the very purpose of giving birth to Him. But first, this passage from the Book of Proverbs sets before us the divine origin of the Son and of the Mother. It is of both that eternal Wisdom says:
“Before the hills I was brought forth: when He prepared the heavens, I was present.”
Our weak human nature, subject to time, can conceive of things only according to the series of their progressive evolutions; but God sees them independently of time, which He rules with His eternity; He sees them in the order of mutual dependence in which He has placed them with a view to the manifestation of His glory. With God, the beginning and the principle of every work is the purpose for which it is done. Now the Most High acts outside Himself solely to reveal Himself, by His Word made Flesh and become the Son of a created Mother as He is the Son of the Creator. The God-Man as end, Mary as the means: such is the object of the eternal decrees, the purpose of the world’s existence, the fundamental conception, with regard to which all else is but accessory and dependent.
O Lady, who dost deign to call us also thy children, it is well for us that thy goodness is equal to thy greatness! Happy is the human race for having waited and watched for thee during so many long ages, and for having found thee at length; for with thee is salvation and life.
