Many of these folks are proud to identify themselves as Calvinists but are they "true" Calvinists? Would John Calvin have accepted them? Listen to Richard Muller, Professor of Historical Theology at Calvin Theological Seminary in Grand Rapids:
I once met a minister who introduced himself to me as a "five-point Calvinist." I later learned that, in addition to being a self-confessed five-point Calvinist, he was also an anti-paedobaptist who assumed that the church was a voluntary association of adult believers, that the sacraments were not means of grace but were merely "ordinances" of the church, that there was more than one covenant offering salvation in the time between the Fall and the eschaton, and that the church could expect a thousand-year reign on earth after Christ's Second Coming but before the ultimate end of the world. He recognized no creeds or confessions of the church as binding in any way. I also found out that he regularly preached the "five points" in such a way as to indicate the difficulty of finding assurance of salvation: He often taught his congregation that they had to examine their repentance continually in order to determine whether they had exerted themselves enough in renouncing the world and in "accepting" Christ. This view of Christian life was totally in accord with his conception of the church as a visible, voluntary association of "born again" adults who had "a personal relationship with Jesus."
In retrospect, I recognize that I should not have been terribly surprised at the doctrinal context or at the practical application of the famous five points by this minister — although at the time I was astonished. After all, here was a person, proud to be a five-point Calvinist, whose doctrines would have been repudiated by Calvin. In fact, his doctrines would have gotten him tossed out of Geneva had he arrived there with his brand of "Calvinism" at any time during the late sixteenth or the seventeenth century. Perhaps more to the point, his beliefs stood outside of the theological limits presented by the great confessions of the Reformed churches—whether the Second Helvetic Confession of the Swiss Reformed church or the Belgic Confession and Heidelberg Catechism of the Dutch Reformed churches or the Westminster standards of the Presbyterian churches. He was, in short, an American evangelical ("How Many Points," Calvin Theological Journal, Vol. 28 (1993): 425-26).
I find it humorous that some Christians fight over "who is the real Calvinist" as if that was somehow a badge of honor. Personally, I find Calvin's theology to be demeaning to God (assuming for a moment that he really does exist). Calvin's God created the world in order to save a chosen few and damn the rest to hell for eternity. Why? Because it brings him glory (Romans 9:22-23) ! Roger Olson, Professor of Theology in the George W. Truett Theological Seminary of Baylor University says: "The God of Calvinism scares me; I'm not sure how to distinguish him from the devil." Thomas Jefferson said:
I can never join Calvin in addressing his god... his religion was Dæmonism. If ever man worshipped a false god, he did. The being described in his 5 points is not the God whom you and I acknowledge and adore, the Creator and benevolent governor of the world; but a dæmon of malignant spirit. It would be more pardonable to believe in no god at all, than to blaspheme him by the atrocious attributes of Calvin (Letter to John Adams, April 11, 1823).Most Calvinists that I have encountered are haughty and arrogant (see Tribalogue and Pyromaniacs). They and they alone have the truth and every other poor soul, including the majority of historical Christianity, is deluded.
