Hi all, I've been reading your posts (in this and two other threads) on Chrono Crusade with interest. Thought I'd toss in my "two cents worth".
I've only seen the first 11 episodes, as here in Australia we tend to get things rather slowly.
Initially I didn't like it because the scientist / inventor was a pervert. I do wish they'd stop putting in those kinds of characters in anime, but the intelligent / perverted combo seems to be a perennial thing in anime (?).
Theologically speaking there are quite a few errors (such as the Astral Line, and Chrono being a "good demon" being the most obvious of the two). To the best of my knowledge there is no textual (Biblical) support for these concepts.
I quite agree that the Japanese (though perhaps not just the Japanese, American comics do this too) twist the beliefs of Christianity and distort them so we get these strange .. things.
The anime "Spriggan" comes to mind.
Having said that, I have found Chrono Crusade so far to be certainly at the "not bad to even fairly good" level - not because it doesn't make any mistakes (factual and otherwise), but because when it comes to content in the context of sexual ethics it's at least better than Ranma 1/2 (which I have watched for a few years during high school). I really liked Ranma 1/2 but felt disappointed that it often had to use sexually immoral content in some of its episodes. Rumiko Takahashi certainly did a better job in Mezzon Ikkoku, in my opinion.
Regarding whether Christians with shaky foundations in their faith should watch this, I'd like to point out that the question perhaps should be "What is our source of supreme authority?"
Considered this way, as long as we know it's ultimately fiction, we can learn to enjoy it without bringing unnecessary doubt to our faith nor be troubled in our consciences when we think about the anime.
I think watching something critically does not mean we cannot enjoy it - the two approaches are not mutually exclusive (as all of you have demonstrated very well - enjoying the anime whilst retaining your powers of reasoning).
Oh and by the way, I liked the opening and closing theme songs.
