Matthew 5:32

This verb is consistently used in the NT to refer to the legal act of divorce. Jesus is not abolishing the institution of divorce per se, but redefining the grounds for its legitimacy, raising the moral and legal standard beyond the lax practices of his time.

This preposition introduces the exception clause. It is crucial to note that it is an exception to the general prohibition of divorce, not an authorization for divorce. The force of Jesus' prohibition remains primary.

The use of the passive ('to be made an adulteress') is significant. It implies that the man who divorces his wife without just cause exposes her to committing adultery if she remarries, and he himself commits adultery if he marries another. This underscores the man's responsibility in unjustified divorce.

Patristic

The Church Fathers showed a diversity of interpretations regarding the 'πορνεία' clause. Origen (184-253), in his *Commentary on Matthew* (Commentarii in Matthaeum, XIV, 16; PG 13, cols. 1229-1232), interpreted 'πορνεία' primarily as post-marital adultery, acknowledging that the Church's practice of his time permitted separation in some cases, though he himself recognized this was not fully consonant with the evangelical ideal. Chrysostom (347-407), in his *Homily XVII on Matthew* (In Matthaeum Homiliae, XVII, 4; PG 57, cols. 258-260), understood 'πορνεία' as fornication or adultery, but insisted with great rigor that the exception only authorized separation, not remarriage: the innocent spouse who remarries commits adultery. Augustine of Hippo (354-430), in his *On the Sermon on the Mount* (De Sermone Domini in Monte, Book I, chapter 14, nos. 38-41; PL 34, cols. 1247-1250), discussed the exception clause and concluded that 'πορνεία' authorizes separation but not remarriage while the other spouse is still living — a position that consolidated throughout his writings and exercised a decisive influence on the Western tradition toward indissolubility. The interpretation of 'πορνεία' as referring to unions illicit from the beginning (incest, forbidden degrees) was held especially by later Eastern authors and also shaped the exegesis of Basil of Caesarea. Overall, the dominant patristic position was that the exception for 'πορνεία' authorizes separation but does not legitimate a new marriage.

Reformed

The Reformed tradition, influenced by Calvin and Luther, generally interprets 'πορνεία' as adultery or serious sexual immorality. Luther, in particular, allowed divorce and remarriage for the innocent party in cases of adultery, based on this clause. Calvin, while emphasizing the permanence of marriage, also recognized the exception for adultery as a breach of the marriage covenant that could justify divorce and, in some cases, remarriage. The tension within this tradition arises in balancing the high view of marriage as an indissoluble covenant with the provision of an exception, and how to apply this pastorally without trivializing divorce.

Interpretive tension: The tension within the Reformed system lies in how God's sovereignty and the sanctity of the marriage covenant are reconciled with the possibility of divorce and remarriage. If marriage is a covenant before God, how can it be dissolved, even by 'πορνεία', without undermining divine will? The system must explain how God's grace operates in the restoration of lives after a justified divorce, without compromising the teaching of ideal indissolubility.

Arminian

The Arminian tradition, following Wesley, also tends to interpret 'πορνεία' as adultery or sexual immorality, allowing divorce and remarriage for the innocent party. However, it emphasizes human responsibility and choice. The tension here is how to maintain the seriousness of Jesus' teaching on the permanence of marriage while acknowledging the reality of human sin and the need for grace and restoration. Strong emphasis is placed on personal holiness and avoiding divorce, but the exception is recognized as a provision for the aggrieved party.

Interpretive tension: The tension within the Arminian system arises in reconciling human agency in the choice to divorce (even for 'πορνεία') with God's will for the permanence of marriage. While the exception is recognized, the system must be careful not to present divorce as an easy 'option,' but as a painful last resort. Grace for remarriage must be balanced with the exhortation to reconciliation and the sanctity of the original covenant, without human freedom eclipsing the divine ideal.

Contemporary

In contemporary exegesis, there are mainly three interpretations of 'πορνεία': 1) 'πορνεία' as pre-marital sexual immorality, rendering the marriage null (the 'annulment thesis,' held by some Catholics and conservative evangelicals). 2) 'πορνεία' as post-marital adultery, allowing divorce and remarriage for the innocent party (the 'adultery thesis,' common in many Protestant denominations). 3) 'πορνεία' as a generic term for any serious sexual immorality, including adultery, incest, etc., that breaks the marriage covenant (the 'general immorality thesis'). Some scholars like David Instone-Brewer argue that Jesus was aligning with the Shammai school, allowing divorce for sexual immorality, and that 1 Corinthians 7:15 adds a second exception for desertion. Others, like William Heth, argue for a stricter interpretation, limiting remarriage.
