From the Council of Friuli, A.D. 796

Canon X. It pleased us that, when the conjugal bond has been dissolved on account of fornication, it is not lawful for the man, as long as the adulteress lives, to lead another wife, although she is an adulteress; but neither is it lawful for the adulteress, who ought to pay the heaviest penalties or the torment of penance, to accept another man, neither while her husband lives nor when he is dead, whom she did not blush to defraud. For even if in the sacred evangelical pages the Lord is read to have said that a man may dismiss his wife for the sole cause of fornication, nevertheless he is not read to have conceded that, while she is living, he may associate another to himself in marriage; and it is not doubted that he prohibited this in every way. For he says: "Whoever has dismissed his wife, except on account of fornication, and has led another, commits adultery; and he who has led her who was dismissed commits adultery."

There follows a declaration from the little book of blessed Jerome, that those words, "except on account of fornication," pertain only to the license of dismissing the wife, but not of leading another.

You see that two things are established by the Fathers: first, that neither the man nor the adulteress, while the other lives, enters another marriage; second, that the adulteress, not even when the husband is dead, should lead another. Only the first is demonstrated from the doctrine of the Lord; for the other was observed only from ecclesiastical law. Cf. the canons of Vermerie.

Canon XI. It pleased us concerning women of whatever condition, girls namely or widows, who, voluntarily promising the purpose of virginity or continence, have been emancipated to God and, as a sign of continence, have put on a black garment, as if religious, just as the ancient custom was in these regions: although they have not been consecrated by a priest, nevertheless we command them to persevere perpetually in this purpose. But if afterward they have corrupted themselves, either secretly, or have publicly married, after having indeed been coerced by fitting bodily punishments by secular judgment, let them be separated from each other and do penance all the days of their life, and be deprived of the communion of the Body and Blood of Christ, etc.
