From Dom Gueranger's The Liturgical Year.
Let us consider how the immaculate Mary came into this world nine months after her conception, and how each day of her life gave man fresh reason to hope for the great promises made him by God. Let us admire the fulness of grace which God has given to her, and contemplate the respect and the love wherewith the holy angels look upon her as the future Mother of Him who is to be their Head and King, as well as ours. Let us follow this august Queen to the temple of Jerusalem, where she is presented by her parents, St. Joachim and St. Anne. When but three years of age, she was initiated into all the secrets of divine love. 'I always rose at midnight (thus she spoke of herself, in a revelation to St. Elizabeth of Hungary), and went before the altar of the temple, where I besought of God that I might observe all the commandments of His Law, and be enriched with those graces which would render me pleasing to His Majesty. I most earnestly prayed Him, that I might live to see that most holy virgin who was to bring forth into this world His own divine Son. I asked Him to grant me to enjoy the use of my eyes that I might see her, of my tongue that I might praise her, of my hands that I might serve her, of my feet that I might go her errands, and of my knees that I might adore the Son of God resting in her arms.’
Thou, O Mary, thou thyself wast this Virgin, who was worthy of the praises of men and angels! But God had not yet revealed it to thee, and thy heavenly humility forbade thy thinking that the immense dignity, which thou didst so deeply venerate, could ever be thine. Nay, thou wast the first and the only one of the daughters of Israel that had renounced all hope of ever being the Mother of the Messias. To be Mother of the Messias was, indeed, an ineffable honour; but it seemed as though it could only be received on the condition of having another spouse besides God, and this thou wouldst not suffer; thou wouldst be united to God alone, and thy vow of virginity which made thee so, was dearer to thee than the possibility of any privilege, which would rob thee of even a tittle of that. Thy marriage with St. Joseph, therefore, was a fresh lustre added to thy incomparable purity, whilst, in the designs of God, it provided thee with the protection which thy coming honours would soon require. We follow thee, O bride of Joseph, into thy house at Nazareth, where is to be spent thy humble life. There we behold thee diligent in all thy duties, the valiant woman of the Scriptures,[1] the object of the admiration of God and of His angels. Suffer us, O Mary! to unite our Advent devotions with the prayers which thou didst offer up for the coming of the Messias; with the veneration wherewith thou didst think upon her that was to be His Mother; and with the inflamed desires wherewith thou didst long for the divine Saviour. We salute thee as the Virgin[2] foretold by Isaias; it is thyself, O blessed Mother, that deservest the praise and love of the holy people and city, the redeemed of the Lord.[3]

Exsultemus, quæsumus, Domine Deus noster, omnes recti corde inunitate fidei congregati: ut veniente Salvatore nostro Filio tuo, immaculati occurramus illi in ejus sanctorum comitatu. Per Christum Dominum nostrum. Amen.
Grant, we beseech thee, O Lord our God, that all we, who are united with upright hearts in the unity of faith, may rejoice: that so, when thy Son our Saviour shall come, we, being purified, may meet him in the society of his saints. Through Jesus Christ our Lord. Amen.
