What Is Hyper-Calvinism?

What is "Hyper-Calvinism"? Phil Johnson has a good primer on the subject:
A fivefold definition: The definition I am proposing outlines five varieties of hyper-Calvinism, listed here in a declining order, from the worst kind to a less extreme variety (which some might prefer to class as "ultra-high Calvinism"):

A hyper-Calvinist is someone who either:
1.Denies that the gospel call applies to all who hear,
2.OR Denies that faith is the duty of every sinner,
3.OR Denies that the gospel makes any "offer" of Christ, salvation, or mercy to the non-elect (or denies that the offer of divine mercy is free and universal),
4.OR Denies that there is such a thing as "common grace,"
5.OR Denies that God has any sort of love for the non-elect.

All five varieties of hyper-Calvinism undermine evangelism or twist the gospel message.

Many modern hyper-Calvinists salve themselves by thinking their view cannot really be hyper-Calvinism because, after all, they believe in proclaiming the gospel to all. However, the "gospel" they proclaim is a truncated soteriology with an undue emphasis on God's decree as it pertains to the reprobate. One hyper-Calvinist, reacting to my comments about this subject on an e-mail list, declared, "The message of the Gospel is that God saves those who are His own and damns those who are not." Thus the good news about Christ's death and resurrection is supplanted by a message about election and reprobation—usually with an inordinate stress on reprobation. In practical terms, the hyper-Calvinist "gospel" often reduces to the message that God simply and single-mindedly hates those whom He has chosen to damn, and there is nothing whatsoever they can do about it.
Deliberately excluded from hyper-Calvinist "evangelism" is any pleading with the sinner to be reconciled with God. Sinners are not told that God offers them forgiveness or salvation. In fact, most hyper-Calvinists categorically deny that God makes any offer in the gospel whatsoever.
