Reformed theology has always had a vibrant community of theologians. John Calvin arguably wrote the first systematic theology with his Institutes of the Christian Religion. Since Calvin’s day, luminaries like John Owen, Charles Hodge, and Louis Berkhof have articulated distinctly Reformed points of view in their now-classic systematic theologies.
In the twentieth and twenty-first centuries, popular pastors and writers such as R.C. Sproul and J.I. Packer brought Calvinism into the mainstream, compelling Time magazine to call New Calvinism one of the “ten ideas changing the world right now.”
