Thanks for your reflections, Sherman. I think your answer to that first question I received was better than my own. When I watched the recording of the forum, I found myself wishing that I had explicitly made the same point that you make about Jesus commanding us to love our enemies as well as those who love us; it was simply not enough to refer vaguely to the Sermon on the Mount. When the questioner was prevented from asking a follow-up question, I also wish I had told him that I was interested in his further thoughts and had invited him to pursue the issue further by email.
A couple of additional points: First, the desire for vengeance or revenge in response to truly horrific acts of cruelty is indeed a natural human response, even among Christians. If John Couey had raped my own daughter when she was young and had buried her alive, as he did to poor little Jessica; and if I had an opportunity to do so, I might well have bludgeoned him to death (slowly) with a baseball bat. I’m not saying that this would have been right or the Christian thing to do. But even within a Christian context, there may be a place for giving butchers a taste of their own medicine—not because this satisfies the demands of justice, but because in some cases it may be the only sort of thing that might get their attention. Even so, however, nothing in the relevant texts about avenging persecution would equate such vengeance with unending torment.
Second, the language of retribution and that of correction often get mixed up in our ordinary ways of speaking, and the Bible is no different in this regard. In a context of vengeance and revenge, for example, a man might use the language of correction: e.g., “I’ll teach him a lesson he’ll never forget!” And in a context of correction, loving parents might use retributive-sounding language: e.g., “If you hit your little sister again, you’ll wish you hadn’t!” So you cannot infer the absence of a loving purpose from harsh language alone. For as Paul points out in the eleventh chapter of Romans, even God’s severest acts, including the hardening and blinding that came upon part of Israel, is an expression of his boundless mercy.
Anyway, thanks again for your reflections.
