The popular reality television series “Sister Wives” has captivated audiences for years, offering an unfiltered look into the lives of Kody Brown and his four wives. Beyond the familial dynamics and interpersonal relationships, a significant driving force behind the family’s lifestyle is their religious affiliation. Understanding the religion of the Sister Wives is crucial to grasping the foundational principles that shape their choices, their community, and their unique interpretation of marriage. The family openly identifies with a specific branch of fundamentalist Mormonism, a practice that sets them apart from mainstream Christianity and often elicits curiosity and questions from the public. This exploration delves into the core tenets of their faith, the historical context of polygamy within their tradition, and how these beliefs manifest in their daily lives.

The Foundations of Fundamentalist Mormonism and Polygamy
The religious beliefs of the Sister Wives are rooted in a denomination often referred to as fundamentalist Mormonism. It’s essential to distinguish this from the mainstream Church of Jesus Christ of Latter-day Saints (LDS Church), which officially renounced polygamy in 1890. Fundamentalist Mormons, conversely, believe that polygamy is a divine commandment and a cornerstone of eternal salvation, as taught by early leaders of the LDS Church, such as Brigham Young. This belief system often traces its origins back to groups that continued to practice polygamy after the LDS Church’s official disavowal, adhering to what they perceive as the original doctrines.
Core Tenets and Beliefs
At the heart of fundamentalist Mormonism lies a profound belief in plural marriage, also known as polygamy or polygyny. Proponents believe that entering into and faithfully living in plural marriages is necessary for attaining the highest degree of celestial glory. This concept is often linked to the idea of celestial marriage, where marriages are believed to be eternal, extending beyond this life. Within this framework, a man can marry multiple women, and each wife enters into a spiritual union with both the husband and, by extension, with his other wives, forming a larger, interconnected family unit. This principle dictates that a man’s spiritual progression is directly tied to his ability to establish and sustain multiple righteous households.
Beyond plural marriage, fundamentalist Mormons often emphasize a strong commitment to patriarchal leadership. The husband is seen as the head of the household, responsible for leading his family spiritually and temporally. This leadership extends to his multiple wives, who are expected to defer to his guidance and authority. The concept of obedience is paramount, not as subservience, but as a willing submission to divine principles and the guidance of their spiritual leader, the husband. This can create complex dynamics within the family, requiring constant communication, negotiation, and a shared understanding of their religious obligations.
Historical Context and Separation from Mainstream LDS Church
To understand the Sister Wives’ religion, it’s crucial to acknowledge the historical schism that led to the emergence of fundamentalist Mormonism. The LDS Church, founded by Joseph Smith in the 19th century, practiced plural marriage for a period. However, facing significant pressure from the U.S. government, including the Morrill Anti-Bigamy Act and the Edmunds-Tucker Act, the LDS Church officially issued the Manifesto of 1890, renouncing polygamy. This led to a division within the faith. Those who believed polygamy was a divine and eternal commandment refused to comply, forming various fundamentalist groups that continued to practice it in secrecy, often in remote communities.
The families featured in “Sister Wives” are descendants of or adherents to these fundamentalist traditions. They often live in communities with other like-minded individuals, fostering a sense of shared identity and mutual support. The historical narrative of persecution and adherence to perceived divine law is a significant element of their religious identity, shaping their worldview and their decision to live openly in a practice that is largely taboo in modern society.
The Practice of Plural Marriage in the Brown Family
The reality show “Sister Wives” offers an intimate glimpse into the daily implementation of plural marriage within the Brown family. While the theoretical underpinnings are vital, observing how these principles are translated into practical living provides a deeper understanding of their religious life. The family’s journey has been marked by their desire to live their faith openly, despite the legal and social challenges this presents.
Legal and Social Challenges

One of the most significant hurdles the Brown family has faced is the legal ramifications of polygamy. In the United States, marriage is legally defined as a union between one man and one woman. Therefore, Kody Brown’s marriages to Christine, Janelle, Mary, and Robyn are not legally recognized as equal unions. Typically, only one marriage is legally registered, with the others being considered common-law marriages or unregistered unions. This legal ambiguity has created a precarious situation for the family, impacting issues such as inheritance, healthcare decisions, and the legal standing of all the wives and their children. The family has openly discussed their desire for legal recognition and the challenges they’ve encountered in seeking to protect their family structure.
Beyond legal battles, the family has also navigated significant social stigma and judgment. Living in a society that largely condemns polygamy as immoral or unethical has meant facing criticism, misunderstanding, and even ostracization. The show itself, while providing a platform for their beliefs, also exposes them to a wide range of public opinion, much of which is negative. Their decision to be transparent about their lives, in part, is an attempt to educate the public and to challenge prevailing prejudices.
Daily Life and Family Dynamics
The practical application of plural marriage involves intricate scheduling, resource management, and emotional negotiation. With Kody as the central figure, the wives and children form a complex web of relationships. The family has often shown the logistical challenges of managing multiple households, ensuring each wife and child receives adequate attention, affection, and resources from Kody. This requires a high degree of organization, communication, and compromise among the wives.
The show highlights the unique sister wife dynamic, where the wives are encouraged to see each other as sisters and to support one another. This is a core tenet of their faith, emphasizing unity and mutual respect within the plural family structure. However, as with any large family, there are also inherent tensions, jealousies, and conflicts that arise, which the show unflinchingly portrays. The wives often discuss their individual relationships with Kody, their feelings about the family dynamics, and their aspirations for their lives and their children’s futures. The children, too, are part of this unique structure, often having numerous siblings from different mothers and navigating the complexities of a polygamous upbringing.
The Role of Faith in Decision-Making and Future Aspirations
For the Brown family, their religious beliefs are not merely a historical or theoretical framework; they actively inform their daily decisions and shape their long-term aspirations. Their faith serves as the compass that guides their choices, from major life events to the mundane aspects of their existence. This deep integration of religion into their lives is a defining characteristic of their identity.
Spiritual Guidance and Moral Framework
The fundamentalist Mormon faith provides the Brown family with a spiritual guidance system and a comprehensive moral framework. This framework dictates not only their marital practices but also their views on raising children, community involvement, and personal conduct. They believe they are living according to divine principles, and this conviction provides them with a sense of purpose and validation, even in the face of societal opposition. Their faith often guides their interactions, their conflict resolution strategies, and their overall approach to life’s challenges.
The concept of eternal progression is a powerful motivator. They believe that their actions in this life have eternal consequences, and that living a righteous life, including the practice of plural marriage, is essential for their eternal salvation and exaltation. This long-term perspective influences their present-day choices, encouraging patience, perseverance, and a focus on spiritual growth.

The Future of Plural Marriage and Their Family
The future of the Brown family and their adherence to plural marriage is a subject of ongoing contemplation and discussion. As their children grow and develop their own perspectives, the family faces the question of whether future generations will continue this religious tradition. Some of the older children have expressed varying degrees of interest or skepticism towards plural marriage, reflecting the challenges of growing up in such a unique environment.
The family’s aspirations for acceptance and understanding also play a significant role in their future. While they are committed to their faith, they also desire a society that is more tolerant and less judgmental of their choices. Their continued participation in reality television can be seen as a long-term strategy to achieve this goal, hoping to foster dialogue and empathy. Ultimately, their future is intertwined with their unwavering commitment to their faith and their hope that their family can continue to thrive according to their deeply held religious convictions.
