By reformed we mean that we hold the reformed creeds and confessions and we seek to prove those truths taught in them from the teachings of sacred scripture. The theology is "reformed" in that the distinctive doctrines of the magisterial Reformers such as Martin Luther, John Calvin and John Knox are also embraced in a way that distinguishes the Reformed tradition from other Protestant bodies. Reformed theology places great emphasis on the doctrine of God, which doctrine is central to the whole of its theology. In short, Reformed theology is God-centered and not man-centered. The structure of the biblical Covenant of Grace is the framework for this theology. The concept of God's grace supplies the core of this theology.
