One of the most debated texts in New Testament studies is the so-called “Matthean Exception Clause,” where Jesus appears to permit divorce in cases of porneia. Since the parallel texts in Mark, Luke, and Paul contain no such exception, the Matthean passages have generated significant exegetical and theological discussion.
The central question is: Does Jesus permit the dissolution of marriage in certain circumstances, or should the exception be understood in another way consistent with His teaching on the indissolubility of marriage?
1. The Matthean Exception Clauses
Matthew 5:32
“But I say to you that everyone who divorces his wife, except on the ground of porneia, makes her commit adultery; and whoever marries a divorced woman commits adultery.”
Matthew 19:9
“And I say to you: whoever divorces his wife, except for porneia, and marries another, commits adultery.”
These two passages are known as the Matthean Exception Clauses because they are found only in the Gospel of Matthew.
2. Parallel New Testament Texts
Mark 10:11–12
“Whoever divorces his wife and marries another commits adultery against her; and if she divorces her husband and marries another, she commits adultery.”
Luke 16:18
“Everyone who divorces his wife and marries another commits adultery, and he who marries a woman divorced from her husband commits adultery.”
1 Corinthians 7:10–11
“To the married I give charge, not I but the Lord, that the wife should not separate from her husband … and that the husband should not divorce his wife.”
The absence of any exception in Mark, Luke, and Paul makes Matthew’s formulation a significant exegetical problem.
3. Why is Matthew Different?
Most scholars agree that Matthew wrote primarily for a Jewish-Christian audience.
His Gospel contains numerous references to:
- Jewish law and customs
- Fulfilment of Old Testament prophecies
- Rabbinic debates
- Issues particularly relevant to Jewish Christians
In Matthew 19:3, the Pharisees ask:
“Is it lawful to divorce one’s wife for any cause?”
This reflects a contemporary Jewish controversy concerning divorce.
The Rabbinic Debate :
Two major schools of interpretation existed:
School of Hillel: Permitted divorce for a wide variety of reasons.
School of Shammai: Permitted divorce only for serious sexual misconduct.
The Pharisees’ question therefore concerns an ongoing Jewish dispute. Matthew’s inclusion of the exception clause may reflect the pastoral and theological needs of his Jewish-Christian readers.
4. The Meaning of the Word Porneia
The key term is the Greek word porneia.
Possible meanings include:
- Sexual immorality
- Fornication
- Illicit sexual union
- Unlawful marriage
The interpretation of this word largely determines the meaning of the exception clause.
5. Major Interpretations of the Exception Clause
A. Adultery Interpretation
Many Protestant interpreters understand porneia as marital infidelity.
According to this view:
Adultery permits both divorce and remarriage.
This interpretation is not accepted by Catholic doctrine because it appears incompatible with the indissolubility of a valid sacramental marriage.
B. Unlawful Union Interpretation
This has been one of the most influential interpretations within the Catholic tradition.
According to this view, porneia refers to unions prohibited by Jewish law, especially those condemned in Leviticus 18.
Examples include:
· Incestuous unions.
· Marriages within prohibited degrees of kinship.
In such cases the relationship is not a valid marriage in the first place.
Thus, Jesus would mean:
Whoever divorces his wife, except in the case of an unlawful union, and marries another commits adultery.
The exception therefore concerns invalid unions rather than the dissolution of a valid marriage.
C. Betrothal Interpretation
Some scholars argue that porneia refers to unchastity discovered during the Jewish betrothal period.
The case of Joseph and Mary (Matthew 1:19) is often cited as background for this interpretation.
D. Separation Interpretation
Some Catholic exegetes understand porneia as grave sexual misconduct within marriage.
However, they maintain that the exception concerns separation from cohabitation, not dissolution of the marriage bond.
Thus, adultery may justify living apart but does not permit remarriage while the spouse remains alive.
6. Catholic Understanding of Separation and Dissolution of Marriage
Catholic doctrine distinguishes carefully between:
Separation
· Living apart for serious reasons.
· Possible in certain circumstances.
· The marriage bond remains intact.
Dissolution
· The ending of the marriage bond itself.
· Impossible in a valid ratified and consummated sacramental marriage.
7 Adultery as a Ground for Separation
The Catholic Church recognizes adultery as a legitimate ground for separation.
A spouse may choose:
· Forgiveness and reconciliation, or
· Separation from the offending spouse.
However:
Separation does not dissolve the marriage bond.
Consequently, neither spouse is free to contract another marriage while the original spouse lives.
8. Witness of the Early Church
The Fathers of the Church consistently defended the indissolubility of marriage.
St. Augustine
Augustine held that adultery may justify separation but not remarriage.
His position may be summarized as:
Separation is permitted; remarriage is not.
This became the dominant Western interpretation and profoundly influenced later Catholic doctrine.
9. Theological Significance
The Matthean exception clause presents three major questions:
A. Textual Problem: Why does Matthew alone include the exception?
B. Lexical Problem: What exactly does the word porneia mean?
C. Theological Problem: How can Matthew’s exception be reconciled with Christ’s teaching on the indissolubility of marriage?
10. Catholic Synthesis
The Catholic Church teaches that the Matthean exception clause does not provide a basis for dissolving a valid sacramental marriage.
The clause is generally understood either:
1. As referring to unlawful or invalid unions (porneia as an illicit marriage), or
2. As permitting separation from cohabitation in cases of grave sexual misconduct without permitting remarriage.
A further reason for this interpretation is the Church's conviction that Sacred Scripture must be interpreted as a unified whole. Any interpretation that allows the dissolution of a valid marriage would be difficult to reconcile with the broader biblical witness concerning the permanence of marriage.
Throughout the Old Testament, marriage is presented as a covenantal bond reflecting God's faithful relationship with His people. In the New Testament, Jesus repeatedly reaffirms the Creator's original plan for marriage (Mt 19:4–6; Mk 10:6–9), while Mark, Luke, and Paul preserve His teaching without any exception permitting remarriage after divorce. Consequently, the Catholic interpretation seeks to harmonize Matthew's exception clause with the consistent biblical teaching on the indissolubility of marriage rather than treating it as a contradiction of that teaching.
Therefore, Matthew’s exception clause does not contradict the teaching found throughout the New Testament that marriage is intended by God to be a permanent and indissoluble covenant.
Conclusion
The Matthean exception clause remains one of the most important and debated texts in biblical theology. While Matthew alone records the phrase “except for porneia,” the Catholic tradition interprets this exception in a manner fully consistent with Christ’s teaching on the permanence of marriage. Adultery may justify separation, but it does not dissolve a valid sacramental marriage. Thus, the Church maintains both fidelity to the Gospel texts and the Lord’s unequivocal teaching: “What therefore God has joined together, let no man put asunder” (Mt 19:6).
