Over at the Riddleblog there is a post by Richard Muller, in which he considers what it means to say you believe in the five points of Calvinism. Muller suggests that there is much more to the historical Reformed faith than a bare confession of adherence to the so-called "five points of Calvinism"--which, incidentally, did not originate with John Calvin. At a time when many are coming to a fuller acceptance of the biblical teaching on the sovereignty of God in all spheres, the efficacy of the atonement Jesus made at Calvary, and the principles of human depravity and inability, Muller raises several important issues to which those who profess a commitment to biblical reformation would be wise to give serious consideration.
