CCC 2347

The virtue of chastity blossoms in friendship. It shows the disciple how to follow and imitate him who has chosen us as his friends,¹³³ Cf. Jn 15:15. who has given himself totally to us and allows us to participate in his divine estate. Chastity is a promise of immortality. Chastity is expressed notably in friendship with one's neighbor. Whether it develops between persons of the same or opposite sex, friendship represents a great good for all. It leads to spiritual communion.
