Tony Jones wants to know whether people think that "The Life of Brian" is an anti-Christian film. And the answer, from my perspective is "yes, clearly it is" and "no, of course not, don't be stupid."
Tony draws our attention to this converstion between Pythons John Cleese and Micahel Palin and two, presumably Christian, critics of the film.
The Christian critique is, apparently, that no non-Christian viewing the film could walk away from it believing about Christianity what Chrisitans believe about Christianity, which is clearly the case. But then, why should they? The point of the film is obviously not to make Christian converts, and the mistake these critics make is in misunderstanding what the film was intended to lampoon.
Cleese and Palin try to make the point repeatedly that the film is sending up forms of religious hypocrisy and fanaticism that distort and undermine the message of Jesus Christ. Palin gets to the heart of the matter when he notes that he can't comprehend how Christians can go to church every week, listen to the Gospel, and yet continue to support war and vote to cut funding for hospitals. The response of the clergyman in the conversation (who Tony identifies as "the guy in the pink robe with the huge pectoral cross") is beside the point. The fact that there are Christians on the right side of the issue doesn't mean very much when the established church of England and the bulk of its members sit idly by and allow things to happen which are contrary to heart of the Gospel that they claim to follow. The most it might serve to prove is that Christians can be found, against all expectations, even in the Church.
And this leads me back to my point above: Yes, The Life of Brian is anti-Christian if you identify Christianity with the established Christian churches, their leaders and their followers. The movie is mercilessly anti-Chrsitian if that is your benchmark for Christianity.
On the other hand, if Christianity is understood in light of the life and teaching of Jesus Christ, then the movie can't be said to be anti-Christian in any regard. Jesus Christ himself is treated with utmost respect throughout the movie. It's those who listen to him and purport to follow him (or his analogue, Brian), that are the butt of every single joke. So in that sense, Christianity isn't even the subject of the movie, never mind something the movie is against. And the movie seems to take no stand whatsoever on the other theological matters of God's existence or Christ's status as the messiah.
Of course, this requires us to make an uneasy distinction between Christ and his church, and that distinction is difficult to make to the degree that Christ is known and followed by this church. But the church is, like the apostles, a fumbling bunch of ninnies, who are usually incapable of finding their ass with both hands, never mind speaking definitively or authoritatively about the revelation of God among God's people.
