Canon 19
About a 4-year penance, as for remarried couples, for those who violated the vow of virginity. That virgins should not cohabit with some as brothers.
Those who take a vow of virginity and break it, let them suffer the punishment of bigamists. We forbade this for virgins who cohabit with someone as sisters.
Greek original
Ὅσοι παρθενίαν ἐπαγγελλόμενοι, ἀθετοῦσι τὴν ἐπαγγελίαν, τὸν τῶν διγάμων ὅρον ἐκπληρούτωσαν. Τὰς μέντοι συνερχομένας παρθένους τισὶν ὡς ἀδελφὰς ἐκωλύσαμεν.
