Hot zeal for God’s judgment to fall on sinners can be a shield protecting the zealot from actually having to practice the harder things such as agape-love (agape being the Greek word used for love in all of these citations) Jesus is talking about. As pointed out in Cold Love, 1, Jesus is talking about the highest form of love (agape) which governs all others. It is this kind of love which we need to live by, and this can only happen in constant relationship with its giver – Yahweh-Adonai, the Creator and Author of all that is.
Most of what passes for commentary consists of dismissing the writer-commentator’s submission as mere strong bias or even some sort of incipient “Communism” or “Fascism”. Lamentably, those accusing “those other people” of being the bogeyman have little real understanding of the ideologies involved, and probably don’t care that they are ignorant thereof. In place of dialogue we are stuck with polemics, histrionics, and ad hominem denunciations of “those Nazis/Commies”.
