Assumpta est Maria in Caelum

"It was fitting that she, who had kept her virginity intact in childbirth, should keep her own body free from all corruption even after death. It was fitting that she, who had carried the Creator as a child at her breast, should dwell in the divine tabernacles. It was fitting that the spouse, whom the Father had taken to himself, should live in the divine mansions. It was fitting that she, who had seen her Son upon the cross and who had thereby received into her heart the sword of sorrow which she had escaped in the act of giving birth to him, should look upon him as he sits with the Father. It was fitting that God's Mother should possess what belongs to her Son, and that she should be honored by every creature as the Mother and as the handmaid of God." - St. John Damascene

Gaudium Mundi - Vespers I: Solemnity of the Assumption

Joy of poor sinners, fairest Star of heaven,
Sun of true justice chose you as his mother;
Save us who perish, raise the sadly fallen,
Mary, pure Virgin.

You were the ladder by which God descended,
Through you the Highest came to seek the lowest;
By your protection, help us as we journey
Onwards to heaven.

Choirs of bright angels throng with joy to meet you,
Saints of the Old Law, prophets and apostles,
Hasten to lead you to your throne of glory
Next to the Godhead.

Praise be forever Trinity most holy,
Who crowned you, Mary, Virgin pure and sinelss,
And save you to us, Queen and loving MOther,
​Now and forever. Amen.

"Hence the revered Mother of God, from all eternity joined in a hidden way with Jesus Christ in one and the same decree of predestination, immaculate in her conception, a most perfect virgin in her divine motherhood, the noble associate of the divine Redeemer who has won a complete triumph over sin and its consequences, finally obtained, as the supreme culmination of her privileges, that she should be preserved free from the corruption of the tomb and that, like her own Son, having overcome death, she might be taken up body and soul to the glory of heaven where, as Queen, she sits in splendor at the right hand of her Son, the immortal King of the Ages." - Munificentissimus Deus: Apostolic Constitution defining the Dogma of the Assumption by Pope Pius XII​

On this blessed solemnity of our Mother, we ask you to join us in praying for our newest Sisters as they begin their postulancy. From her glorious throne in heaven, may the Blessed Virgin Mary be their Mother, Mistress, and Guide on this journey of their religious life. O Mary, assumed into heaven, pray for these - your dearest daughters - and obtain for them every grace to persevere in their holy vocation. 

Almighty everlasting God, Who hast taken body and soul into heaven the Immaculate Virgin Mary, Mother of Thy Son: grant, we beseech Thee, that by steadfastly keeping heaven as our goal, we may be counted worthy to join her in glory." - Collect, Mass of the Solemnity of the Assumption
