30 Worthy of special consideration is the reflection that the most delicate fruit of virginity consists in this, that virgins make tangible, as it were, the perfect virginity of their mother, the Church and the sanctity of her intimate union with Christ. In the ceremony of the consecration of virgins, the consecrating prelate prays God: "that there may exist more noble souls who disdain the marriage which consists in the bodily union of man and woman, but desire the mystery it enshrines, who reject its practice while loving its mystic signification."
