The first is that in Mary it is fruitful, whilst in the Angels it is sterile. The virginity of Mary is not only fruitful in having produced and borne the sweet fruit of life, our Blessed Saviour, but it is fruitful also because it produces a multitude of virgins, for (as we observed in the preceding consideration) if so many young persons dedicate and consecrate their purity to God, it is that they may follow her example. But the pure virginity of Mary not only possesses the property of being fruitful, it can also restore virginal purity in those souls who have defiled this virtue by the contrary vice. In her lifetime she had already called many virgins to follow her, who became her inseparable companions; among others, St. Martha and St. Marcella. But it was also through her means that St. Mary Magdalen, who had been the scandal of Jerusalem, was enrolled after her conversion under the standard of virginal purity, and became like a brilliant crystal vase, capable of receiving and containing the most precious waters of grace. The virginity of Our Lady, therefore, is not sterile, like that of the Angels, but it is so fruitful that from the moment she vowed it to God, until the present time, it has always borne its fruit. A soul that is perfectly dedicated to the service of God is never alone; many others, drawn by the sweetness of its perfumes, flock after to copy its example. It is on this account that the Spouse says to her Beloved: _Trahe me post te, curremus--'Draw me and we shall run.'_ Secondly, the virginity and chastity of the Blessed Virgin surpassed that of the Angels in this, that they are chaste by nature; and we do not, properly speaking, praise a person for the gifts of nature, since praise is not due where there is no merit. But the virginity of the Most Holy Virgin is, on the contrary, worthy of praise, because it was chosen and preferred by her, and consecrated by her to God. Although she was united in marriage to St. Joseph, it was without any prejudice to her virginity, because he to whom she was espoused had also consecrated his virginity to God. Thirdly, the virginity of Our Lady surpassed that of the Angels, because it was subjected to the severest trials, whilst that of the Angels could never be tempted or tried. In this sense St. Augustine, addressing the Angels, says: 'It is not difficult for you, O blessed spirits! to be pure and remain virgins, because you neither are, nor can be, tempted.'
