Covenant theology is an interpretive framework used by Reformed theologians which was significantly developed during the seventeenth century. Under this scheme, as articulated by the Assembly, God's dealings with men are described in terms of two covenants: the covenant of works and covenant of grace. The Westminster Confession was the first major Reformed symbol to explicitly mention the covenant of works (sometimes called the covenant of life), in which God offered Adam eternal life on condition of perfect obedience. In the fall of man, Adam broke the covenant of works by eating of the tree of knowledge of good and evil. To remedy this, God offered salvation apart from human initiative in what was called the covenant of grace. This covenant allowed man to enjoy eternal life despite his inability to obey God's law perfectly. The idea of the covenant of grace was a much more common feature of orthodox Reformed theology. The Westminster divines set these two covenants against each other as the two major ways in which God deals with people.
