What Does the Torah Say About Marriage? A Comparative Religious Overview

The Torah is the foundational source of Jewish marriage law, and its rulings are developed extensively in rabbinic literature, particularly the Mishnah tractate Yevamot. Marriage in Jewish law isn't just a social contract—it's a legally binding religious institution with specific rules about who may marry whom, and what obligations arise from that union.

One of the Torah's clearest marriage prohibitions concerns intermarriage with certain foreign peoples. In Deuteronomy, Abraham's servant is charged with finding a wife for Isaac from within the covenant community, not from the surrounding Canaanites Genesis 24:3. This principle is later codified more explicitly: "Neither shalt thou make marriages with them; thy daughter thou shalt not give unto his son, nor his daughter shalt thou take unto thy son" Deuteronomy 7:3. Scholars like Jacob Milgrom (in his 2000 Leviticus commentary) note this wasn't purely ethnic but covenantal—protecting Israelite religious identity.

The Torah also prohibits adultery as one of the Ten Commandments: "Neither shalt thou commit adultery" Deuteronomy 5:18. This single commandment generated enormous rabbinic discussion. The Mishnah in Yevamot elaborates on forbidden sexual unions (arayot), specifying that a man who has relations with a woman forbidden to him—such as a widow with a High Priest or a divorcée with a common priest—disqualifies her from certain priestly privileges Mishnah Yevamot 6:2. Rabbi Tarfon and Rabbi Akiva disagreed sharply on how to handle edge cases, such as when a man betrothed one of five women but couldn't identify which—Rabbi Akiva insisting on the stricter remedy to prevent any possible transgression Mishnah Yevamot 15:7.

The ketubah (marriage contract) is also a Torah-rooted institution, ensuring a wife's financial protection. It's worth noting that Jewish marriage law is detailed, contested, and evolving—Orthodox, Conservative, and Reform communities interpret these Torah passages quite differently today.

Christianity inherits the Torah's teachings on marriage but interprets them through the lens of the New Testament and centuries of theological development. The prohibition on adultery from the Decalogue remains fully authoritative for Christians Deuteronomy 5:18, and the New Testament book of Hebrews affirms the Torah's positive view of the institution itself: "Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge" Hebrews 13:4.

The specific Torah prohibition against marrying into certain foreign peoples (Deuteronomy 7:3) Deuteronomy 7:3 is generally not applied literally in Christian theology. Most mainstream Christian scholars—including John Calvin in his 16th-century Commentaries—interpreted that passage as historically specific to ancient Israel's covenantal situation, not a binding rule for the church. The New Testament shifts the concern from ethnic or national identity to shared faith: Paul's instruction in 2 Corinthians 6:14 ("be not unequally yoked") is often cited as the Christian functional equivalent.

The Torah's framework of marriage as a sacred, regulated institution is affirmed broadly across Christian denominations. However, Christians don't observe the detailed rabbinic elaborations found in the Mishnah [[cite:7], [cite:8]]—those are considered part of the ceremonial law that Christ's coming fulfilled or superseded, depending on one's theological tradition. Catholic, Orthodox, and Protestant traditions each developed their own canon law around marriage, drawing selectively from Torah principles.

Islam doesn't derive its marriage law from the Torah directly—Islamic jurisprudence is rooted in the Quran and Sunnah, not the Hebrew scriptures. That said, the Hadith literature does reflect overlapping Abrahamic concerns about who may and may not be married.

The Prophet Muhammad forbade a man from being simultaneously married to a woman and her paternal or maternal aunt: "The Prophet forbade that a woman should be married to a man along with her paternal aunt or with her maternal aunt (at the same time)" Sahih al Bukhari 5111. This prohibition is extended by analogy to foster-suckling relationships as well Sahih al Bukhari 5110—a distinctly Islamic legal concept with no direct Torah parallel.

On the question of choosing a spouse, the Prophet's guidance is practical and spiritually prioritized: "A woman is married for four things, i.e., her wealth, her family status, her beauty and her religion. So you should marry the religious woman (otherwise) you will be a loser" Sahih al Bukhari 5090. This hadith, recorded in Sahih al-Bukhari, is widely cited by scholars like Ibn Hajar al-Asqalani (d. 1449) in Fath al-Bari as evidence that piety should outweigh worldly considerations in choosing a spouse—a sentiment that resonates with Torah-based Jewish and Christian values even if the legal source differs.

The Torah prohibits adultery as a core command of the Decalogue, shaping the moral boundary of marriage within Israel Deuteronomy 5:18.

It also bans intermarriage with the Canaanite nations, framing communal and covenantal concerns in spouse selection Deuteronomy 7:3.

Patriarchal narrative illustrates this boundary when Abraham makes his servant swear not to take a Canaanite wife for Isaac, favoring kinship endogamy Genesis 24:3.

Rabbinic law later elaborates these Torah boundaries with detailed categories of forbidden unions and priestly ineligibilities, and it regulates complex betrothal and ketubah disputes to prevent transgression Mishnah Yevamot 6:2Mishnah Yevamot 15:7.

The New Testament affirms that “marriage is honourable in all” and warns that God will judge the sexually immoral and adulterers, reflecting continuity with the Torah’s prohibition of adultery Hebrews 13:4Deuteronomy 5:18.

Christians also read the Torah’s regulation of marriage boundaries, such as the ban on intermarriage with Canaanite nations, as part of Israel’s covenantal history in the biblical canon Deuteronomy 7:3.
