I think he's just a troll. Or an idiot. Doesn't matter either way. On pretty much every forum you get a couple of hardcore trolls who's mission is just to annoy and aggravate people, and usually there is one who is overly-religious and won't actually listen to anything anyone is saying because they're so fundamentally fixed in their views (or trolling). I don't see why he would be state-sponsored though and there's certainly no evidence for that, but of course it is the sexiest conspiracy theory.

If there's any paid trolls here then they will probably be paid by rival companies to attack other services, and if there's any government backed ones (which I personally find unlikely) then I think they'd probably be spreading more fud about bitcoin rather than just posting easily refutable crap about Christianity.
