The Complexities Of Brother-Sister-In-Law Marriages

The question of whether a brother and sister-in-law can marry is complex and depends on cultural, religious, and legal perspectives. From a legal standpoint, marrying a sibling-in-law is permissible as long as there is no direct blood relation. In some cultures, it may be uncommon or considered taboo, but it is not illegal. However, from a religious perspective, the answer varies. For instance, in Islamic law (Sharia) and Jewish law (halakha), sexual relations between siblings-in-law are prohibited as incestuous unless the spouse is no longer married. In contrast, the Bible suggests that while God initially allowed brothers and sisters to marry, He later prohibited such marriages in Leviticus 18:6, classifying them as incest.

Can brother and sister-in-law get married?

Brother and sister-in-law marriage in the Bible

In the Bible, a brother and sister-in-law are related by a type of kinship called affinity, which is similar to all in-law relationships. This means that they are not related by blood. While the Bible does not explicitly state whether or not a brother and sister-in-law can marry, it does provide guidelines and principles that suggest such a union is not condoned.

For example, in Ezekiel 22:11 (NASB), the Bible condemns sexual relations between a man and his sister, referring to it as an "abomination". This suggests that any sexual relationship between a brother and a sister, whether by blood or affinity, is prohibited.

Furthermore, in 1 Peter 2:13-14 (NASB), the Bible instructs believers to submit themselves to human institutions, including the laws of their state and government. If the laws of their state or government prohibit marriage between a brother and sister-in-law, then the Bible would advise against such a union.

Additionally, the concept of levirate marriage in the Bible, which is now extinct, may provide some insight. Levirate marriage, as outlined in Deuteronomy 25:5–6, commanded Israelites to care for women whose husbands died before they had children. In this case, the unmarried brother of the deceased man was expected to marry his sister-in-law to continue the family line and preserve the inheritance within the tribe. While this practice may suggest a level of acceptance for marriages between a brother and sister-in-law, it is important to note that these marriages were specifically between a widow and her late husband's brother, and the primary purpose was to bear children who would carry on the late husband's name and inherit his property.

In summary, while the Bible does not explicitly address the marriage between a brother and sister-in-law, it provides guidelines that suggest such a union is not condoned. Sexual relations between siblings, whether by blood or affinity, are prohibited, and believers are instructed to follow the laws of their state and government, which may prohibit such marriages. While levirate marriage in the past may have involved marriages between a widow and her late husband's brother, the primary purpose was to continue the family line and preserve inheritances, rather than a choice based on romantic love or attraction.

Islamic and Jewish law on the marriage

Islamic Law on the Marriage of Brother and Sister-in-Law

Islamic law does not explicitly address the marriage of a brother and sister-in-law. However, it does provide guidelines regarding living arrangements with in-laws. According to Islamic teachings, a husband should respect his wife's wishes if she does not want to live with her in-laws, such as his mother, sister, or daughter from another marriage. In such cases, the husband is obligated to provide separate accommodation for his wife.

Jewish Law on the Marriage of Brother and Sister-in-Law

In Jewish law, the concept of a brother marrying his sister-in-law is related to the practice of levirate marriage or "yibbum." This custom is described in Deuteronomy 25:5–10, where the brother of a man who died without children is permitted and even encouraged to marry the widow. This serves as an exception to the biblical prohibition against a man having sexual relations with "his brother's wife," as outlined in Leviticus 18:16 and 20:21.

However, Jewish law also provides an alternative to levirate marriage called "halizah" or "chalitzah." If the brother-in-law refuses to marry his sister-in-law, they must perform the halizah ceremony, which involves symbolic acts of renunciation. During this ceremony, the widow takes off the brother-in-law's shoe, symbolizing mourning, and spits on the ground to show contempt. After this ceremony, the widow is free to marry anyone she chooses.

Over time, the preference within Jewish law has shifted from levirate marriage to halizah. This change is attributed to concerns about the brother's intentions and the potential for incestuous relationships. Today, yibbum is rare among Jewish communities, and in Israel, it has been prohibited by the Chief Rabbinate.

It is worth noting that Jewish incest law prohibits a woman from marrying her deceased husband's brother, as mentioned in Deuteronomy 25:5–10. This prohibition is part of the broader Jewish religious law regarding marriages between specific individuals, such as close relatives.

Marrying an in-law: taboo or not?

Marrying an in-law is not illegal as long as there is no direct blood relation. In fact, it is more common than one might think. People who spend a lot of time together often develop feelings for each other. For instance, there are instances of parent in-laws marrying each other, and brother/sister in-laws marrying each other.

However, in Islamic law (Sharia) and Jewish law (halakha), sexual relations between siblings-in-law are prohibited as incestuous, unless the spouse is no longer married. In Judaism, there was a custom of yibbum, where a man had a non-obligatory duty to wed his deceased brother's childless widow so that she might have progeny by him.

In the Bible, it is stated that God no longer allowed brothers and sisters to marry, with the first prohibition mentioned in Leviticus 18:6. However, if a brother and sister marry without knowing that it is prohibited and later realize their mistake, they are not required to get a divorce. Instead, they can confess their sin, and God will forgive them.

While not illegal, marrying an in-law may be considered taboo or unusual by some families and cultures. It may raise eyebrows and lead to conflicted opinions. However, others may view it as an opportunity to bring two families closer together and foster new relationships. Ultimately, the decision to marry an in-law depends on personal and cultural beliefs, as well as the legal framework of the region.

What to do if you're already married to your sibling's spouse

In most places, it is not illegal for a person to marry their sibling-in-law, or the spouse of their sibling. In Islamic law (Sharia) and Jewish law (halakha), sexual relations between siblings-in-law are prohibited as incestuous unless the spouse is no longer married. In Judaism, there was a custom of yibbum, where a man had a non-obligatory duty to wed his deceased brother's childless widow.

In the past, affinity laws invalidated marriages between siblings-in-law in some cultures and religions. However, these laws have since been abolished, and a person can marry their sibling-in-law without legal repercussions in most places.

If you are already married to your sibling's spouse, there are a few things you should consider and steps you can take:

• Understand the legal implications: While it may be legally permissible to marry your sibling's spouse, it is important to consult with a legal professional to understand any specific laws or regulations that may apply in your jurisdiction.
• Seek family counselling: Marrying your sibling's spouse can have complex emotional and relational dynamics. It is essential to seek family counselling to help navigate these dynamics and ensure healthy relationships between all parties involved.
• Establish clear boundaries: It is crucial to set clear boundaries and communicate openly with your spouse and sibling. Discuss and agree upon the level of involvement and interaction you are all comfortable with to maintain a respectful and harmonious relationship.
• Consider extended family relationships: Marrying your sibling's spouse can impact relationships with extended family members, such as parents, aunts, uncles, and cousins. Be prepared to address any concerns or objections they may have and work towards fostering understanding and acceptance.
• Prioritize self-care: This situation can be emotionally challenging and stressful. Prioritize self-care and seek individual counselling or join support groups to process your emotions and ensure your well-being.
• Legal documentation: Ensure that you have all the necessary legal documentation for your marriage. This includes a marriage license, which needs to be signed by at least one witness, and the officiant's filing of the license with the local government recording agency.

Remember, while there may not be legal restrictions on marrying your sibling's spouse, it is important to approach this situation with sensitivity and empathy towards all involved parties.

Twins marrying twins: an example of brother and sister-in-law marriage

The concept of twins marrying twins can be considered an example of a brother and sister-in-law marriage. While it might seem unconventional, such unions are not unheard of and present an intriguing dynamic within the realm of relationships and in-law terminology.

Let's consider the scenario of identical twin brothers Jeremy and Caleb Baker, who married another set of identical twin sisters, Kristen and Brooklyn Stutler. In this case, Jeremy is Kristen's brother-in-law, and vice versa. Simultaneously, Caleb is Brooklyn's brother-in-law, and she is his sister-in-law. This reciprocal relationship creates a unique situation where each twin is both a sibling and a sibling-in-law to their own twin.

The intricacies of in-law relationships are fascinating. A sibling-in-law is the spouse of one's sibling or the sibling of one's spouse. It's important to note that these relationships are not directly related by blood but are connected through a type of kinship called affinity. In Indian English, there is a specific term called "co-sibling" to refer to this dynamic.

In the context of twins marrying twins, the in-law relationships become even more intertwined. For instance, in the case of Jeremy, Caleb, Kristen, and Brooklyn, the twins are not only siblings to each other but also brothers-in-law and sisters-in-law due to their marriages. This double relationship adds an extra layer of complexity to their family connections.

While the idea of twins marrying twins and the resulting brother and sister-in-law relationships might raise eyebrows in certain cultures, it's important to note that these unions are not prohibited by law in most places. However, in Islamic law (Sharia) and Jewish law (halakha), sexual relations between siblings-in-law are considered incestuous and are prohibited unless the spouse is no longer married.
