Biblical law places the family at the center of society because God entrusts it with decisive powers: children (the future), property, inheritance, education, and welfare. When these are taken over by the state, society weakens. True renewal comes as families reclaim these responsibilities through Christian education, care for their own, and faithful stewardship.

Rushdoony argues that this reclamation fails unless families are intellectually and spiritually grounded. Worldviews built on chance, evolution, or inevitable conflict make struggle metaphysical and unavoidable turning marriage, society, and economics into battlegrounds that require state control. By contrast, creationism affirms God’s sovereign order, so conflict is moral, not inevitable, and can be governed by God’s law.

The family is therefore not merely biological or social but a religious institution, created to serve God’s kingdom. Husband and wife are “heirs together of the grace of life,” called to harmony and obedience. The future of society depends not on politics but on re-Christianizing the family, restoring its God-given authority, and living out covenant faithfulness.
