Canon 87
She who has left her husband is an adulteress if she has come to another, according to the
holyand divine Basil, who has gathered this most excellently from the
prophet Jeremiah: If a
woman has become another man's, her husband shall not return to her, but being defiled she shall remain defiled; and again, He who has an adulteress is senseless and impious. If therefore she appears to have departed from her husband without reason, he is deserving of pardon and she of punishment. And pardon shall be given to him that he may be in communion with the
Church. But he who leaves the wife lawfully given him, and shall take another is guilty of
adultery by the sentence of the Lord. And it has been decreed by our Fathers that they who are such must be weepers for a year, hearers for two years, prostrators for three years, and in the seventh year to stand with the faithful and thus be counted worthy of the Oblation [if with tears they do
penance].
