It is often said that the church needs to return to the New Testament church. What is meant is a return to Biblical Christianity. This is precisely what the reformers sought to do. While the reformed faith passionately affirms the ancient universal creeds of the church, it also produced some of the richest and most detailed creeds that the church has ever known such as the Three Forms of Unity (Belgic Confession, Canons of Dort, Heidelberg Catechism) and the Westminster Confession of Faith. It is in these documents that the only infallible rule of faith and practice, Holy Scripture, is so faithfully and brilliantly confessed.
Reformed theology is sometimes termed Pauline, sometimes Augustinian, and popularly Calvinist. While all of this is true enough, the great Pastor Theologian C.H. Spurgeon put it best when he said,
Reformed theology is nothing other than biblical Christianity.
