Why Polygamy No Longer Applies in the New Covenant

 Why Polygamy No Longer Applies in the New Covenant


Polygamy is one of those practices in Scripture that many Christians today find puzzling. While it was never directly commanded by God, it was clearly permitted and even regulated under the Old Covenant. But like many other practices from the Old Testament, polygamy was part of a cultural and covenantal structure that has since passed away.


Polygamy, Like Tithing and Sacrifices, Was Pre-Law but Not Eternal


Polygamy, like tithing, circumcision, and animal sacrifices, existed before the Mosaic Law. Abraham practiced it. Jacob lived it. Yet these practices, though preceding the Law, were codified into Israel's covenantal life for practical and redemptive reasons. They served a purpose in a world shaped by tribal survival, patriarchal structures, and covenantal symbols. But that doesn’t mean they were meant to be permanent.


Just as animal sacrifices were never God's ultimate desire (Psalm 40:6; Hebrews 10:8), polygamy was never God's ideal for relationships. Jesus pointed back to the beginning, saying, “from the beginning it was not so” (Matthew 19:8). He reaffirmed the Genesis vision of one man and one woman becoming one flesh. That original creation pattern reflects God's design—one that the New Covenant fully restores.


Practical Purposes, Not Eternal Principles


Polygamy had cultural and economic functions. It was often used to provide for widows, preserve family lines, and prevent poverty. In a world with limited options for women, being part of a polygamous household could mean safety and stability. In that sense, it was a mercy—much like how levirate marriage or even indentured servitude functioned under the Old Covenant.


But over time, polygamy became corrupted by power. David and Solomon didn’t practice polygamy to serve others—they used it to build political alliances and display dominance. They turned a provision into a status symbol. That was never God's intent. God tolerated it, but He never glorified it.


The New Covenant Makes Polygamy Obsolete


By the time of the New Testament, polygamy had already begun to fade. Under Roman rule, Jews were restricted by Roman family laws, which upheld monogamy as the legal and cultural norm. As the gospel spread through the Roman world, believers began to reflect the one-man, one-woman ideal more clearly. The qualifications for church leaders in the epistles (1 Timothy 3:2, Titus 1:6) require being the husband of one wife, not because leaders were held to a higher moral standard, but because that was the standard of Christian marriage.


Additionally, the social fabric was changing. Women in the Greco-Roman world had more access to economic opportunities and legal protections than in ancient Israel. The need for polygamy to preserve legacies or provide financial security diminished.


70 AD and the End of the Old System


With the destruction of the temple in 70 AD, the old covenantal system came to a definitive end. The shadows passed away, and the realities of the New Covenant stood alone. Just as we no longer sacrifice animals or demand tithes, we no longer practice polygamy. It belonged to an old world—one marked by types and shadows, survival and substitution.


Today, in Christ, we live out the restored ideal of creation: mutual, monogamous covenant love that reflects Christ and the Church. Polygamy may have had a place in the unfolding story of redemption, but it has no place in the new creation.
