St. Amadeus of Lausanne (d. 1159), in France, came from a noble family, but renounced the world in order to follow The Lord as a Cistercian in the early days of that order.  Like his master, St. Bernard of Clairvaux, he possessed a fervent devotion to the Blessed Virgin Mary.  The following is from his homily on the Feast of her glorious Assumption into heaven:

"Why did not The Lord's Mother, who was filled with such great love for him, follow him immediately, when he ascended into heaven?  It seems strange that she was not immediately borne aloft into the air with her Son since no cloud of sin weighed her down, no stain was splattered on her life, she was redder than fire because of her charity, and burned more brightly than it because of the rarity of the virginal birth.  Certainly, Enoch walked with God in the innocence of his heart, and he was seen no more, for God took him (cf. Genesis 5, 24).  And we recall that Elijah burned with a very great fire of charity, and was caught up in a fiery chariot with fiery horses (cf. 4 Kings 2, 11).  But why was she not carried into heaven from that place -- she, who exceeded Enoch on purity of heart, and preceded Elijah in love?  After all, she was 'full of grace' and 'blessed among women' (Luke 1, 28).  She alone merited to conceive true God from true God, bore him as a Virgin, fed him as a Virgin, warmed him in her bosom, and ministered sweet duty to him in all things.  At length, she suffered more in spirit than in her flesh when he was dying, revived in the Spirit of God when he rose.  Why should she not rise with him when he ascended into heaven?  Her most sacred body was made pregnant by the Holy Spirit and was made large by the sprouting of the great King (cf. Isaiah 11, 1).  The God-man, 'the Word made flesh', and the fullness of divinity dwelt in it through Christ the Mediator.  It would seem only right for this flesh to be carried up to heaven with the Ascension of her Son.  What slows here?  Why does she suffer separation from her Son?  Why is her most holy desire, burning with fire, delayed?  This delay was, at the very least, a consolation for the disciples of Christ.  This delay took nothing from the Mother, and conferred the remedy of salvation to the world.  The Lord willed, when he returned to the Father, for the Apostles to be nourished by Maternal solace and teaching.  Although, Indeed, they were taught by the Holy Spirit, they were still able to be taught by her who brought forth to the world the Sun of Justice and the Image of Wisdom, from her virginal field, in a basket without stain."
