Majority opinion can never be the right one in a world of mostly ignorant peoples. Our world has not yet overcome the bane of ignorance and superstitions. The majority people in this world are now followers of a religion founded in the name of Jesus Christ. The second most prominent religion too rever Jesus Christ as holy personality. But yet, none of them would perhaps give some heed to what Jesus had actually taught. This was what happened when Jesus himself moved among the common people of Israel and Palestine in his times. They followed him more for his miracles than for practising what he preached.
If Jesus would make a second appearance now just as a common human being, none of the Christians would ever believe him. Only power and pomp can make a difference to it. Such a situation is because we all lack the ability to understand truth from untruth to varying degrees.
So the Christians would not accept any thing other than the Bible as the word of God. Traditional customs and practices are much stronger than the meanings of any writings ! For Christians all other books which tells some other concepts other than the Bible, even when they are not some thing bad after all, are not palatable and not acceptable.
