27 The fruit of virginity is not only in these external works, to which it allows one to devote oneself more easily and fully, but also in the earnest prayer offered for others and the trials willingly and generously endured for their sake, which are other very perfect forms of charity toward one's neighbor. To such also the servants and spouses of Christ, especially those who live within the convent or monastery walls, have consecrated their whole lives.
