Direct Answer
The early Christian sources supplied here understood divorce and remarriage in a very strict way: marriage is God’s joining of a man and woman, divorce was a concession to human hardness of heart, Christ restored marriage to its original permanence, and remarriage after divorce was treated as adultery.
The clearest line of evidence comes from Jesus’ own teaching as quoted and explained by the early Christian writers. Tertullian states the Lord’s rule this way: “Christ prohibits divorce, saying, ‘Whoever puts away his wife and marries another commits adultery; and whoever marries a woman put away from her husband also commits adultery.’” He then explains that Christ forbids divorce by making it unlawful to marry a divorced woman.
The early writers also recognized a difference between separation and remarriage. In one passage, Tertullian quotes the apostolic rule that if a wife departs, she is to “remain unmarried or be reconciled to her husband”. Justin Martyr tells of a Christian woman who separated from an immoral and violent way of life with her husband “to avoid becoming a participant in his wickedness,” but that account is about separation and persecution, not permission to remarry.
So, in short: the early Christians represented in these sources did not treat divorce as a normal option, and they did not treat remarriage after divorce as permissible. Separation could be discussed in exceptional moral circumstances, but remarriage after divorce was condemned or denied.
What Scripture Says
No separate Scripture text rows were supplied, but the early Christian sources quote and expound the key biblical passages directly. Their argument begins with Jesus.
1. Jesus: Moses permitted divorce because of hardness of heart, but “from the beginning it was not so”
Irenaeus, in Against Heresies, explains Jesus’ answer to the question about Moses and divorce:
“When they asked Him, ‘Why then did Moses command us to give a certificate of divorce and send a wife away?’ He replied, ‘Because of the hardness of your hearts, he permitted these things to you; but from the beginning it was not so.’”
Irenaeus draws several conclusions from this. First, Jesus was not attacking Moses as though Moses belonged to a different god or a lower moral order. Rather, Jesus was “clearing Moses as a faithful servant” while criticizing the people’s hardness of heart. Second, Irenaeus says the divorce law was “tailored to their hard nature.” In other words, the Mosaic permission was a concession, not the original will of God for marriage.
Irenaeus then broadens the principle. He says that even in the New Testament, the apostles sometimes gave instructions “in consideration of human weakness,” citing Paul’s language: “But these things I say, not the Lord,” and “But this I speak by permission, not by commandment.” His point is not that Christ’s command can be set aside, but that Scripture itself distinguishes God’s original intention and firm command from concessions given because of human weakness.
For the question of divorce, Irenaeus’ witness is important because he presents Jesus’ teaching as a return to the beginning: divorce was not God’s original design.
Tertullian makes the same argument in Against Marcion. He quotes Jesus’ answer:
“Moses,” He says, “because of the hardness of your hearts, allowed you to give a bill of divorcement; but from the beginning it was not so.”
Then Tertullian adds the creation text as Jesus used it:
“For this reason, because He who made them male and female had also said, ‘The two shall become one flesh.’ ‘Therefore what God has joined together, let not man put asunder.’”
This establishes the basic early Christian reasoning: marriage is not merely a private contract that one spouse can dissolve. It is something God joins. Human divorce is therefore described as an attempt to separate what God has joined.
2. Jesus: remarriage after divorce is adultery
Tertullian states Christ’s prohibition very plainly:
“But Christ prohibits divorce, saying, ‘Whoever puts away his wife and marries another commits adultery; and whoever marries a woman put away from her husband also commits adultery.’ Luke 16:18”
He immediately interprets the logic of the command:
“To forbid divorce, He makes it unlawful to marry a woman who has been put away.”
This is one of the clearest statements in the supplied sources. Tertullian does not merely say divorce is unfortunate, unwise, or socially disruptive. He says Christ prohibits it, and he explains that Christ’s prohibition works by denying remarriage: the man who divorces and marries another commits adultery, and the man who marries a divorced woman also commits adultery.
That means remarriage is not treated as forming a clean new union after divorce. The continuing force of the first marriage is assumed. Otherwise, remarriage after divorce would not be adultery.
3. Paul: if separation happens, remain unmarried or be reconciled
Tertullian also cites Paul’s teaching in Against Marcion:
“Even Christ, however, when He here commands the wife not to depart from her husband, or, if she does depart, to remain unmarried or be reconciled to her husband, 1 Corinthians 7:10-11, both permitted divorce, which indeed He never absolutely prohibited, and confirmed the sanctity of marriage by first forbidding its dissolution.”
This sentence needs careful reading. Tertullian says Christ “never absolutely prohibited” divorce in the sense that separation may occur; but he does not say the separated person may remarry. Quite the opposite: the rule he cites is that if departure happens, the person must “remain unmarried or be reconciled.”
He continues:
“And if separation had taken place, He wished the marriage bond to be resumed by reconciliation.”
So the early Christian reading of Paul, at least in this passage, distinguishes between physical or household separation and the dissolution of the marriage bond. Separation does not create freedom to marry someone else. The goal remains reconciliation, and the alternative is remaining unmarried.
4. Paul: Tertullian says the divorced are not granted permission to marry
In On Monogamy, Tertullian discusses Paul’s statements about being “loosed” from a wife. He insists that the “loosing” in view is death, not divorce:
“The loosing having taken place through death, of course, not through divorce. For to the divorced he would grant no permission to marry, against the primary precept.”
This is another very direct witness. Tertullian reads Paul as allowing remarriage after death in some cases being discussed, but not after divorce. For the divorced, he says, Paul “would grant no permission to marry.” The reason is “the primary precept,” that is, the foundational command of Christ concerning the permanence of marriage and the adultery involved in remarriage after divorce.
What the Early Christian Writers Say
Irenaeus: divorce was a concession to hard hearts, not God’s original design
Irenaeus’ discussion in Against Heresies is not mainly a pastoral manual about divorce. It is part of a larger argument about the unity of God’s work in the Old and New Testaments. Still, his comments on divorce are directly relevant.
He says the Lord showed that some rules were given through Moses because of Israel’s “stubbornness and unwillingness to obey.” The divorce command is his example:
“Because of the hardness of your hearts, he permitted these things to you; but from the beginning it was not so.”
Irenaeus’ conclusion is that Moses’ divorce law was not the highest expression of God’s will for marriage. It was “this law of divorce, tailored to their hard nature.”
That is an important early Christian interpretation. It means the Christian norm is not established by asking only, “What did Moses permit?” The Christian norm is established by Christ’s restoration of the creation purpose: “from the beginning it was not so.”
Irenaeus also notes that God sometimes gives concessions “for the benefit of His people” in order to restrain worse evils. But those concessions do not erase the original good. Applied to divorce, the Mosaic permission regulated hard-hearted people; Christ calls His disciples back to the beginning.
Tertullian: Christ prohibits divorce and forbids remarriage after divorce
The strongest supplied witness is Tertullian, especially in Against Marcion. He writes:
“But Christ prohibits divorce, saying, ‘Whoever puts away his wife and marries another commits adultery; and whoever marries a woman put away from her husband also commits adultery.’”
Then he explains:
“To forbid divorce, He makes it unlawful to marry a woman who has been put away.”
Tertullian’s argument is not merely that Christians should avoid divorce if possible. He presents the Lord’s command as prohibiting divorce because remarriage after divorce is adulterous. He also contrasts Moses and Christ:
“You see, therefore, that there is a difference between the law and the gospel, between Moses and Christ.”
But he immediately guards that contrast from becoming a rejection of Moses. Christ, he says, explains why Moses permitted divorce:
“Because of the hardness of your hearts.”
And Christ restores the Creator’s institution:
“What God has joined together, let not man put asunder.”
Tertullian therefore sees continuity and fulfillment. Moses gave a concession for hard hearts; Christ restores marriage to the Creator’s purpose.
Tertullian: separation is not the same as permission to remarry
In another passage from Against Marcion, Tertullian quotes Paul’s rule:
“The wife [is] not to depart from her husband, or, if she does depart, to remain unmarried or be reconciled to her husband.”
He says this both “confirmed the sanctity of marriage” and showed that if separation happened, Christ “wished the marriage bond to be resumed by reconciliation.”
This is the key distinction in the supplied sources. Tertullian can speak of a kind of “divorce” or departure in the sense of separation, but the separated person remains bound to the marriage. The evidence for that is the command to remain unmarried or be reconciled. If the marriage bond had been dissolved, reconciliation would not be the named goal, and remarriage would not be forbidden.
In On Monogamy, Tertullian makes the same point from another angle:
“For to the divorced he would grant no permission to marry, against the primary precept.”
So in Tertullian’s reading, divorce does not create a right to a new marriage.
Tertullian: God joins; man must not separate
In On Monogamy, Tertullian also states the Lord’s teaching in a compressed dogmatic form:
“Yet the Lord spoke of this when He dealt with divorce. Divorce had been allowed before, but now He forbids it. First, because from the beginning it was not so, just as having many marriages was not so. Second, because, ‘What God has joined together, man must not separate’—so that a man may not oppose the Lord.”
Here again the logic is simple and strong. Divorce is forbidden because marriage is God’s act of joining. To divorce is to “oppose the Lord” by separating what He joined.
This passage goes beyond divorce and connects the argument to Tertullian’s wider strict teaching about marriage. In the supplied excerpt, he even argues against remarriage after death, saying that just as man must not separate what God joined, man must not join what God separated by death. That particular extension is stricter than the divorce question itself. But the divorce portion is clear: he says divorce “had been allowed before, but now He forbids it.”
Justin Martyr: a Christian woman separated from a wicked husband
Justin Martyr provides a different kind of evidence in The Second Apology. He tells a narrative about a Christian woman married to a heavy-drinking and immoral husband. After learning “the teachings of Christ,” she became sober-minded and tried to persuade her husband to live temperately, warning him of judgment. He continued in excess and worsened.
Justin says:
“She considered it wicked to continue living as a wife with a husband who sought pleasure in ways contrary to natural and moral law and wanted a divorce.”
Friends persuaded her to stay for a time, hoping he might change. But later, when he went to Alexandria and was reported to be acting worse, Justin says:
“She, to avoid becoming a participant in his wickedness through marriage, gave him a bill of divorce and separated from him.”
This account is significant because it shows an early Christian source recognizing a grave situation in which a Christian woman separated from a wicked husband. Justin does not present her as immoral for separating. Rather, the husband becomes the persecutor, accusing her of being a Christian and then targeting Ptolemaeus, her teacher.
However, this passage does not say she remarried. It does not say separation dissolved the marriage bond before God. It does not give a general rule permitting remarriage after divorce. Its value is narrower: it shows that at least in an extreme case involving serious wickedness, separation could be seen as a way to avoid participation in evil.
That fits the distinction already seen in Tertullian’s use of Paul: if departure occurs, the rule is not remarriage, but remaining unmarried or reconciliation.
Tertullian: apostolic teaching is received through Christ and the apostles
One supplied passage from Tertullian’s On Prescription Against Heretics does not discuss divorce directly, but it helps explain why these writers argue as they do. Tertullian says:
“Since the Lord Jesus Christ sent the apostles to preach, our rule is that no others should be accepted as preachers except those whom Christ appointed.”
He continues that what the apostles preached is what “Christ revealed to them,” and that this can be proved through the churches founded by the apostles. This does not itself prove any particular divorce teaching, but it explains the early Christian method: the Lord’s teaching comes first, the apostolic teaching follows, and Christian practice is measured by that received rule.
On divorce and remarriage, the supplied sources follow exactly that order. They begin with Christ’s words, then cite Paul’s apostolic instruction, and then apply those teachings to Christian discipline.
What Is Explicitly Stated
Several points are explicitly stated in the supplied sources.
1. Moses permitted divorce because of hardness of heart
Irenaeus quotes Jesus:
“Because of the hardness of your hearts, he permitted these things to you; but from the beginning it was not so.”
Tertullian quotes the same explanation and says Moses’ allowance must be understood in light of the Creator’s original institution.
2. From the beginning, divorce was not God’s design
Both Irenaeus and Tertullian emphasize the phrase “from the beginning it was not so.” Tertullian connects it with creation:
“He who made them male and female had also said, ‘The two shall become one flesh.’”
3. What God joins, man must not separate
Tertullian quotes the Lord’s command:
“Therefore what God has joined together, let not man put asunder.”
And in On Monogamy he applies it directly:
“What God has joined together, man must not separate.”
4. Remarriage after divorce is adultery
Tertullian quotes Christ:
“Whoever puts away his wife and marries another commits adultery; and whoever marries a woman put away from her husband also commits adultery.”
Then he interprets:
“To forbid divorce, He makes it unlawful to marry a woman who has been put away.”
5. If separation happens, the person is to remain unmarried or be reconciled
Tertullian cites 1 Corinthians 7:10-11:
“If she does depart, to remain unmarried or be reconciled to her husband.”
And he adds:
“If separation had taken place, He wished the marriage bond to be resumed by reconciliation.”
6. The divorced are not granted permission to marry
Tertullian says directly:
“For to the divorced he would grant no permission to marry, against the primary precept.”
That is one of the most direct answers to the remarriage part of the question.
What Is Strongly Implied
1. The marriage bond was viewed as continuing after divorce
The adultery language strongly implies that the original marriage bond continues despite divorce. If divorce fully dissolved the marriage, then marrying another would not be adultery. Tertullian’s explanation confirms this: Christ forbids divorce by making remarriage unlawful.
2. Separation could be tolerated in grave situations, but not as freedom to remarry
Justin’s account of the Christian woman shows separation from a wicked husband. Tertullian’s citation of Paul allows for the possibility that someone “does depart.” But the supplied sources do not turn that departure into permission for a new marriage. The stated options are remaining unmarried or reconciliation.
3. The Christian standard was understood as stricter than the Mosaic concession
Tertullian says plainly:
“There is a difference between the law and the gospel, between Moses and Christ.”
The difference is not that Moses was evil or that the Creator changed. Rather, Moses regulated hard-heartedness; Christ restored the beginning.
4. Early Christian discipline was shaped by Jesus’ command, not by Roman civil divorce norms
Justin’s account mentions a woman giving a bill of divorce, but the theological sources do not treat civil divorce paperwork as dissolving the marriage before God. Tertullian’s statements point in the opposite direction: man must not separate what God joined, and the divorced are not granted permission to marry.
What These Sources Do Not Address
Several limits should be stated clearly.
1. The supplied sources do not give a full pastoral procedure for every abusive or dangerous marriage
Justin gives one narrative of a Christian woman separating from a wicked husband. Tertullian quotes the apostolic rule about departure and reconciliation. But these excerpts do not provide a complete church process for cases of violence, abandonment, legal danger, protection of children, or other complex pastoral situations.
2. The supplied excerpts do not provide a detailed discussion of every biblical exception clause
The sources quoted here emphasize Luke 16:18, Matthew 19:8, Matthew 19:4 and 19:6, and 1 Corinthians 7:10-11. They do not, in the supplied excerpts, analyze every possible interpretation of every exception clause in Matthew. Therefore, this answer should not pretend to settle debates not addressed in these sources.
3. The sources do not say Justin’s separated woman remarried
Justin’s story is sometimes important for discussions of separation, but the supplied excerpt does not mention remarriage. It should not be used as evidence that remarriage after divorce was permitted.
4. Tertullian’s *On Monogamy* includes a stricter argument about remarriage after death
Some supplied passages from On Monogamy go beyond divorce and discuss whether widows or widowers may remarry. That is related to Tertullian’s wider strict view of marriage, but it is not the same as divorce and remarriage. The clearest divorce-specific statements are his claims that Christ forbids divorce, that remarriage after divorce is adultery, and that the divorced are not granted permission to marry.
5. These sources do not represent every Christian writer of every century
The evidence here includes Irenaeus, Justin Martyr, and Tertullian, with several Tertullian passages being especially direct. It is enough to show a strong early Christian witness in the supplied materials, but it is not a complete survey of every ancient Christian text.
Summary
The supplied early Christian evidence gives a clear answer.
Irenaeus says Jesus explained Mosaic divorce as a concession to “the hardness of your hearts,” adding, “from the beginning it was not so.” For Irenaeus, the divorce law was “tailored to their hard nature,” not the Creator’s original purpose for marriage.
Tertullian gives the most direct statements. In Against Marcion, he quotes Christ: “Whoever puts away his wife and marries another commits adultery; and whoever marries a woman put away from her husband also commits adultery.” He then explains, “To forbid divorce, He makes it unlawful to marry a woman who has been put away.” In another passage, he cites the apostolic rule that if a wife departs, she must “remain unmarried or be reconciled to her husband.” In On Monogamy, he says plainly: “For to the divorced he would grant no permission to marry.”
Justin Martyr shows that separation could occur in an extreme moral situation: a Christian woman separated from a husband whose conduct was gravely wicked, “to avoid becoming a participant in his wickedness.” But Justin does not say she remarried, and his account does not overturn the rule stated by Tertullian from Paul: remain unmarried or be reconciled.
Therefore, according to these sources, the early Christians believed that divorce was contrary to God’s original design, permitted by Moses only because of hardness of heart, forbidden by Christ as a dissolution of what God joined, and that remarriage after divorce was adultery. Separation might be recognized in severe circumstances, but remarriage after divorce was not presented as permissible in the supplied evidence.
