An Old Testament Defense Against Polygamy
The New Testament writers don’t introduce this as new — they reiterate what marriage was designed for from the beginning: a picture of Christ’s singular, covenantal love for His Church (Eph. 5:22-33), as this article will show. Polygamy doesn’t just violate a command. It corrupts that picture.
This argument is essential for understanding and refuting the heresy of so-called “Christian” polygamists and polygynists who believe they are introducing a legitimate, alternate morality that is biblically defensible. It isn’t. It turns the theology of marriage on its head.
