" No less important than the ideal of martyrdom was that of virginity, which also goes back to the first age of the Church. Indeed the two ideals were associated - first by the cult of virgin martyrs, like St. Agnes, which was so popular, and secondly by the idea that virginity was a kind of living martyrdom, a witness to the power of the faith to transcend human weakness.
