Virginity and Humility

A friend has written with a seasonal quotation from Bernard of 
Clairvaux's sermons on Advent:

"Who is this Virgin so reverently saluted by the angel? and so lowly
as to be espoused to a carpenter ? Beautiful commingling of
virginity with humility! That soul is in no small degree pleasing to
God, in whom humility commends virginity, and virginity adorns
humility. But how much more worthy of veneration is she, in whom
fecundity exalts humility, and child-bearing consecrates virginity.
