The Assembly worked in the Reformed Protestant theological tradition, also known as Calvinism. It took the Bible as the authoritative word of God, from which all theological reflection must be based. The divines were committed to the Reformed doctrine of predestination — that God chooses certain men to be saved and enjoy eternal life rather than eternal punishment. There was some disagreement at the Assembly over the doctrine of particular redemption — that Christ died only for those chosen for salvation. The Assembly also held to Reformed covenant theology, a framework for interpreting the Bible. The Assembly's Confession is the first of the Reformed confessions to teach a doctrine called the covenant of works, which teaches that before the fall of man, God promised eternal life to Adam on condition that he perfectly obeyed God.
