A reader writes:
The view of Christ catching the Devil with a baited hook described by your reader is often referred to as the Ransom view of the Atonement. More recently, it's been called the Christus Victor view. It's the one I personally prefer. And it's the one depicted in C.S. Lewis' "The Lion, The Witch and the Wardrobe." If you're interested, Greg Boyd has a great essay on Christus Victor.
Boyd also delivers a riveting history lesson above.
