Reformed Foundations

The Five Solas, TULIP, and Covenant Theology

We begin where the Reformers began: Sola Scriptura—Scripture alone as the church’s final and sufficient authority. From this axiom flow the remaining Solas, the doctrines of grace (TULIP), and the unity of the Bible in God’s covenants.
