Catechism of the Catholic Church
922 From apostolic times Christian virgins 461 and widows, 462 called by the Lord to cling only to him with greater freedom of heart, body, and spirit, have decided with the Church's approval to live in the respective states of virginity or perpetual chastity "for the sake of the Kingdom of heaven." 463
923 "Virgins who, committed to the holy plan of following Christ more closely, are consecrated to God by the diocesan bishop according to the approved liturgical rite, are betrothed mystically to Christ, the Son of God, and are dedicated to the service of the Church." 464 By this solemn rite (Consecratio virginum), the virgin is "constituted . . . a sacred person, a transcendent sign of the Church's love for Christ, and an eschatological image of this heavenly Bride of Christ and of the life to come." 465
924 "As with other forms of consecrated life," the order of virgins establishes the woman living in the world (or the nun) in prayer, penance, service of her brethren, and apostolic activity, according to the state of life and spiritual gifts given to her. 466 Consecrated virgins can form themselves into associations to observe their commitment more faithfully. 467
