In this case we get: "Gibson tells us that what made Jesus special was not that he lived righteously but that he died bloodily." Um.. yeah. Because the latter brought us salvation, while the former gave us our example of Christian virtue. Nothing wrong with examples of Christian virtue, but salvation ranks higher on the list of import for Christians.
This would be obvious to any self-described "PASSIONATE ADMIRER of the Christian community" who was passionate enough to educate himself about why Christians have placed such central importance on the passion of Christ for the past two millenea. In artwork, prayer, and theology there can be no denying that Christ's "bloody death" has a pretty darn important role on by itself in the Christian faith. It doesn't take personal belief in that to show a basic understanding of it, and tolerance for it among a group you claim to admire.
It takes a staggering amount of ego-centrism to ignore Christian understanding of the Christian faith, and focus solely on what it means to Jews. News-flash: American Christians don't have pogroms against the Jews. The suggestion that viewing this movie is going to lead them to it is simultaneously a stupid reading of history, and a thumb in the eye of modern Christians.
It's very insightful to see people like Mr. Boteach equating American Christians with proto-Nazis, which is essentially what this critique amounts to. In his eyes, we're a couple of propagandistic movies away from lighting the ovens of our own Auschwitz. Nice to know what your "passionate admirers" truly think about you.
Eloquently stated.
