28 Finally, virginity consecrated to Christ is in itself such an evidence of faith in the kingdom of heaven, such a proof of love for our Divine Redeemer, that there is little wonder if it bears abundant fruits of sanctity. Innumerable are the virgins and apostles vowed to perfect chastity who are the honor of the Church by the lofty sanctity of their lives. In truth, virginity gives souls a force of spirit capable of leading them even to martyrdom, if needs be: such is the clear lesson of history which proposes a whole host of virgins to our admiration, from Agnes of Rome to Maria Goretti.
