da vinci code

your statement about "nobody know if it is wrong" is false, because many "historic" information in that book is already proved to be wrong by "ppl who study history" (not christian), and in the book they relates all those false historic information together with God, this already creates a problem which you cannot say it is right. Since many historic information is proved to be wrong already, the claims involving those historic informations in the book are also be wrong
You have to be clear about one thing, Christian never attacked Da Vinci Code with any religious idea, so your point about "use a religious way to judge the something attacking religion, it will be always false" doesn't even exist in this issue. Christian have proved the claims of the book to be false by HISTORIC ANALYSIS and SCIENTIFIC VIEW through professions, you will just have to read more about this issue before claming that "Da Vinci Code could be right" or "Christian attacked Da Vinci Code with just some undetermined religious idea". Scholars with reputations throughout the world have already proved the claims the book made about God is false, I think you just have to read more. I guess you can really say that Christian actually DID used theorem to prove that things claimed by that book is false.
I will stop here, since i already posted an answer to this to some other post.
Now you should see why ppl don't like this book, because it makes ppl think that Da vinci Code is right or it could be right, while those stuff is proved to be wrong, not by Christian, but by ppl who study history or science. (note: PROVED to be wrong, not christian believe it's wrong, it is very scientific, just do more research). you said this "nobody know if it is wrong", so the book affected you too, so how can people not oppose to that book.
