Saint Bernard of Clairvaux is the last of the ancient church Fathers. He founded the Abbey of Clairvaux and was renowned both for his own personal sanctity and for his theological and spiritual writings. He also is called the "Troubadour of Mary," as he had an incredibly deep devotion to the Blessed Mother.
A monk who lived before Bernard, named Radbertus, once wrote this: "Mary is your sister." Bernard read this and must have pondered the relationship with his own sister, Humbeline, in his contemplation and exposition of Mary.
Bernard loved his little sister, Humbeline, though for a while he was disappointed in her. Married to a wealthy nobleman of Lorraine, it was said Humbeline "was more notable for dancing than devotion." Bernard refused to see her until she changed. One day he wrote a simple note to her: "Remember our mother's virtue."
So moved by this comment, Humbeline persuaded her husband, Guy de Marcy, to let her become a nun. She entered the convent, was elected abbess, and lived a great life of prayer and penance. In fact, when her sisters thought her self-denial and asceticism too extreme, she responded, "That is all very well for you, my sisters, who have been serving God in religion all your lives. But I have lived so long in the world and of the world that no penance can be too much for me."
Humbeline's four brothers were all incredibly proud of their sister. None was prouder than Bernard, who held his little sister, eventually canonized a saint, as she died in his arms.
Brothers have a fatherly care for their sisters and take great pride in them. A sister can prompt an individual to holiness. Saint Humbeline did for Bernard, as Mary, our little sister, can for us.
