Do you know why your scholars dont come out in the open and try to refute the claims? Because they are very knowledgable of the bible and quran, and they know exactly where they'll end up if they do try to refute. Yet their hearts are sealed.
Islam is the only religion that poses a challenge right out in the open.
Bring a chapter LIKE in the Quran (in arabic, of course).
Prove a SINGLE verse wrong, just ONE! All that is sufficient.
The challenge is open to anyone...pass anyone and I will become a christian.
Complete anyone(not both, just one) of those challenges.
Our scholars(comparative religion) come right out in the open for Quran and Bible debates. After what Dr. Zakir Naik did to Dr. William Campbell (check on www.aswatalislam.net (videolectures, drzakirnaik, quran and bible in teh light of science)), it seems as if the christian scholars have been cowering. They only preach against islam in their churches, but not in the open, because they're afraid.
