Consecrated virgins
"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. Consecrated virgins can form themselves into associations to observe their commitment more faithfully.
