Answer
The Reformed Churches, notably the Reformed Churches in the Netherlands (Liberated), is a major Protestant denomination that traces its roots to the Dutch Calvinist tradition of the 17th century. Abraham Kuyper, a Dutch theologian and statesman, played a pivotal role in the establishment and development of the Reformed Churches. Kuyper's theological vision, known as neo-Calvinism, emphasized the sovereignty of God in all areas of life, including politics, education, and culture.
