"Speaking of world in the theological sense"? Think Could you elaborate on that? How is the world in the theological sense different from the world in the actual sense?"
The use here is of 'world' in the materialistic, narcissistic, selfish, ambitious, egotistic, rationalizing (ie, I'm stealing this guy's cupcake, but its ok), I am my own master, I am god, sense.
This certainly can dovetail into the sense that you took it as but it need not. See for example John 3:16-21 and 15:18
"Well i'll work on that. It looks like a good skill to have, especially if it allows one to claim exemption for any statement made which in retrospect appears to be incoherent, contradictory or flat-out delusional by explaining that it was meant "in the theological sense". If only there was a secular version of that..."
There is a secular version of that. It's called "every word that comes out of the secular mouth."

No, but seriously, this is really a reach, don't you think? an exemption for 'any statement'? When was the last time you saw someone deploy this exemption? No, it is perfectly reasonable for words to be used within a certain context which might be taken by others differently. Medical terminology, for example. Theoretical physics (like, 'spin'). And if you asked me to mail you a rubber the reaction would be different then if I asked you to send me a rubber. Cuz you're in England and all.*
But I would protest the point you think is 'incoherent' or delusional. You like to think that Christianity holds all this sway and any concern they might have about being persecuted is unfounded.
That is incoherent and delusional. But I don't expect you to see it or agree. You are, after all, part of the world.

"Good luck for today Big Chief. You know i'm rooting for McCain and the She-Bush all the way."
I'm sure you are. But luck won't have anything to do with it. :)
