Jacobus Arminius, a Dutch minister-teacher-reformer born in 1560, called for religious tolerance, human liberty, and for a free church founded only upon the Holy Scriptures. Opposing certain doctrinal and ecclesiastical developments of Calvinism and the Reformed Church, Arminius advocated the universal atonement of Christ and the freedom of man to accept or reject this salvation. The five papers and sermon contained here were delivered at the Arminius Symposium in Holland in 1960. They trace the events of Aruminius's life, the essence of his theology, and his influence in Europe, England, and America.
