When Jesus came, he elevated matrimony to the same status it had originally possessed between Adam and Eve—the status of a sacrament. Thus, any valid marriage between two baptized people is a sacramental marriage and, once consummated, cannot be dissolved. Jesus, therefore, taught that if anyone so married divorces and remarries, that person is living in perpetual adultery, a state of mortal sin.
He said, “Everyone who divorces his wife and marries another commits adultery, and he who marries a woman divorced from her husband commits adultery” (Luke 16:18; cf. Mark 10:11–12).
Paul was equally insistent on this fact, declaring, “Thus a married woman is bound by law to her husband as long as he lives. . . . Accordingly, she will be called an adulteress if she lives with another man while her husband is alive” (Rom. 7:2–3).
This applied, of course, only to sacramental marriages—those between baptized people. For marriages involving an unbaptized party, a different rule applied (1 Cor. 7:12–15).
In the midst of the Greco-Roman culture, which allowed for easy divorce and remarriage, the early Church Fathers proclaimed Christ’s teaching on the indissolubility of marriage—just as the Catholic Church does today in our modern, secular, easy-divorce culture (Catechism of the Catholic Church 1614–1615). Other denominations have modified their teachings to accommodate the pro-divorce ethos that dominates modern culture, but the Catholic Church preserves the teaching of Jesus and the early Christians.
While their ex-spouses are alive, the only time that a baptized couple can remarry after divorce is when a valid sacramental marriage never existed in the first place. For example, for a marriage to be contracted, the two parties must exchange valid matrimonial consent. If they do not, the marriage is null. If the competent authority (a diocesan marriage tribunal) establishes this fact, a decree of nullity (commonly called an annulment) can be granted, and the parties are free to remarry (CCC 1629). In this case there is no divorce followed by remarriage in God’s eyes because there was no marriage before God in the first place.
If, however, the parties are genuinely and sacramentally married, then, while in some cases there may be good reasons for them to live apart and even to obtain a legal separation, in God’s eyes they are not free to remarry (CCC 1649).
This is not a commandment of men, but one that comes directly from Jesus Christ. As Paul said, “To the married I give charge, not I but the Lord, that the wife should not separate from her husband (but if she does, let her remain single or else be reconciled to her husband)—and that the husband should not divorce his wife” (1 Cor. 7:10-11).
Fortunately, God will ensure that the sacramentally married have the grace necessary to live out their marriage vows and either stay married or live continently. The sacrament of matrimony itself gives this grace. Whenever we face a trial, God ensures that we will have the grace we need. As Paul elsewhere says, “No temptation has overtaken you that is not common to man. God is faithful, and he will not let you be tempted beyond your strength, but with the temptation will also provide the way of escape, that you may be able to endure it” (1 Cor. 10:13).
As the following quotations from the early Church Fathers illustrate, they also recognized the seriousness of Christ’s teaching regarding the indissolubility of marriage.
“What then shall the husband do, if the wife continue in this disposition [adultery]? Let him divorce her, and let the husband remain single. But if he divorce his wife and marry another, he too commits adultery” (The Shepherd 4:1:6 [A.D. 80]).
“In regard to chastity, [Jesus] has this to say: ‘If anyone look with lust at a woman, he has already before God committed adultery in his heart.’ And, ‘Whoever marries a woman who has been divorced from another husband, commits adultery.’ According to our Teacher, just as they are sinners who contract a second marriage, even though it be in accord with human law, so also are they sinners who look with lustful desire at a woman. He repudiates not only one who actually commits adultery, but even one who wishes to do so; for not only our actions are manifest to God, but even our thoughts” (First Apology 15 [A.D. 151]).
Clement of Alexandria
“That Scripture counsels marriage, however, and never allows any release from the union, is expressly contained in the law: ‘You shall not divorce a wife, except for reason of immorality.’ And it regards as adultery the marriage of a spouse, while the one from whom a separation was made is still alive. ‘Whoever takes a divorced woman as wife commits adultery,’ it says; for ‘if anyone divorce his wife, he debauches her’; that is, he compels her to commit adultery. And not only does he that divorces her become the cause of this, but also he that takes the woman and gives her the opportunity of sinning; for if he did not take her, she would return to her husband” (Miscellanies 2:23:145:3 [A.D. 208]).
“Just as a woman is an adulteress, even though she seem to be married to a man, while a former husband yet lives, so also the man who seems to marry her who has been divorced does not marry her, but, according to the declaration of our Savior, he commits adultery with her” (Commentaries on Matthew 14:24 [A.D. 248]).
Council of Elvira
“Likewise, women who have left their husbands for no prior cause and have joined themselves with others, may not even at death receive Communion” (Canon 8 [A.D. 300]).
“Likewise, a woman of the faith [i.e., a baptized person] who has left an adulterous husband of the faith and marries another, her marrying in this manner is prohibited. If she has so married, she may not receive Communion—unless he that she has left has since departed from this world” (Canon 9).
“If she whom a catechumen [an unbaptized person studying the faith] has left shall have married a husband, she is able to be admitted to the fountain of baptism. This shall also be observed in the instance where it is the woman who is the catechumen. But if a woman of the faithful is taken in marriage by a man who left an innocent wife, and if she knew that he had a wife whom he had left without cause, it is determined that Communion is not to be given to her even at death” (Canon 10).
Ambrose of Milan
“No one is permitted to know a woman other than his wife. The marital right is given you for this reason: lest you fall into the snare and sin with a strange woman. ‘If you are bound to a wife do not seek a divorce’; for you are not permitted, while your wife lives, to marry another” (Abraham 1:7:59 [A.D. 387]).
“You dismiss your wife, therefore, as if by right and without being charged with wrongdoing; and you suppose it is proper for you to do so because no human law forbids it; but divine law forbids it. Anyone who obeys men ought to stand in awe of God. Hear the law of the Lord, which even they who propose our laws must obey: ‘What God has joined together let no man put asunder’” (Commentary on Luke 8:5 [A.D. 389]).
“So long as a husband lives, be he adulterer, be he sodomite, be he addicted to every kind of vice, if she left him on account of his crimes, he is her husband still and she may not take another” (Letters 55:3 [A.D. 396]).
“Wherever there is fornication and a suspicion of fornication, a wife is freely dismissed. Because it is always possible that someone may calumniate the innocent and, for the sake of a second joining in marriage, act in criminal fashion against the first, it is commanded that when the first wife is dismissed, a second may not be taken while the first lives” (Commentaries on Matthew3:19:9 [A.D. 398]).
Pope Innocent I
“[T]he practice is observed by all of regarding as an adulteress a woman who marries a second time while her husband yet lives, and permission to do penance is not granted her until one of them is dead” (Letters 2:13:15 [A.D. 408]).
“A woman begins to be the wife of no later husband unless she has ceased to be the wife of a former one. She will cease to be the wife of a former one, however, if that husband should die, not if he commit fornication. A spouse, therefore, is lawfully dismissed for cause of fornication; but the bond of chastity remains. That is why a man is guilty of adultery if he marries a woman who has been dismissed even for this very reason of fornication” (Adulterous Marriages 1:9:9 [A.D. 419]). .
“Undoubtedly the substance of the sacrament is of this bond, so that when man and woman have been joined in marriage they must continue inseparably as long as they live, nor is it allowed for one spouse to be separated from the other except for cause of fornication. For this is preserved in the case of Christ and the Church, so that, as a living one with a living one, there is no divorce, no separation forever” (Marriage and Concupiscence 1:10:11 [A.D. 419]).
“In marriage, however, let the blessings of marriage be loved: offspring, fidelity, and the sacramental bond. Offspring, not so much because it may be born, but because it can be reborn; for it is born to punishment unless it be reborn to life. Fidelity, but not such as even the unbelievers have among themselves, ardent as they are for the flesh. . . . The sacramental bond, which they lose neither through separation nor through adultery, this the spouses should guard chastely and harmoniously” (ibid., 1:17:19).
