Sphere sovereignty is a concept that emphasizes the independence and authority of different social institutions, such as the family, church, and state. Each sphere has its own responsibilities and should operate without interference from others. This idea promotes the belief that various aspects of life should be governed by their own unique principles and norms. The term is often associated with the work of Abraham Kuyper, a Dutch theologian and politician. He argued that recognizing sphere sovereignty helps maintain a balanced society, where each institution can flourish and contribute to the common good without overstepping its boundaries.
