Calvinist Phil Johnson has said, “History teaches us that hyper-Calvinism is as much a threat to true Calvinism as Arminianism is. Virtually every revival of true Calvinism since the Puritan era has been hijacked, crippled, or ultimately killed by hyper-Calvinist influences” (http://www.spurgeon.org/~phil/articles/hypercal.htm).
Might this be because hyper-Calvinism is the logical conclusion to the distinctive doctrines of Calvinism? Perhaps regular Calvinism simply refuses to go where its own doctrine logically leads because where it leads contradicts the Bible so blatantly.
