Dr. James Galyon has an interesting post on the topic of Hyper-Calvinism. He provides a long list of items that he views as Hyper-Calvinism, many of which I would agree with. I may not agree with him in every last detail in his definition. For example, he includes as one form of hyper-Calvinism: "Scripture is to be interpreted only by individuals, not by the Church." While that position is wrong, I wouldn't necessarily see it being an error under the umbrella of hyper-Calvinism.
Here's his post.
