A more truthful and appropriate response to these anti-Bible claims is to say, “I am going to do research about The Da Vinci Code, so I will really know the truth.”
For years after the book, and then the movie about the book, came out, I refused to read or watch anything that had to do with it. I have studied the Bible for the all of my 74 years (yes, the Bible was read to me as an infant by my family) and I will now and forever stand on the truth that Scripture was inspired by God and written down by men under the inspiration of God. As a proof to this I present what John Wesley had to say:
“The Bible must be the invention either (1.) of good men or angels, (2.) of bad men or devils, or (3.) of God.
It could not be the invention of good men or angels; they neither would nor could make a book, and tell lies all the time they were writing it, saying, “Thus says the Lord,” when it was their own invention.
It could not be the invention of bad men or devils; for they would not make a book which commands all duty, forbids all sin, and condemns their souls to hell to all eternity.
Therefore, I draw this conclusion, that the Bible must be given by divine inspiration. ”
The Bible is real and true and as Paul stated “all scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: 17 That the man of God may be perfect, thoroughly furnished unto all good works” 2 Timothy 3:16
A Harvard professor, fictional or real, to most is a legit source of information. Why would someone question a person of the level of intellect of a Harvard professor. Again, it is easier to rely on what is TOLD to you by a person who seems qualified than it is to actually do your own research and form your own understanding. To understand and know truth, you must seek.
People like mystery. The church hiding a big secret would appeal to the masses. An appropriate response would be to actually read the Bible, study the history of the Bible. This would take away those false claims
People in general are not quick to do their own research and will take the word of a credible source instead. If the author claims that he has backing from professors and that his book is historical, people will take it as is. I think people would be quick to believe Dan Brown due to their sin nature as well. These anti-Bible claims are unfounded pieces of flair for the fictional book and story with the intention of causing a stir. They are false.
