Is it possible that secret societies took the Bible and rewrote it to say what they want us to know? Is there not an Almighty God that can protect the Word of God to get US the TRUTH?
Aside from the fact that God calls the Bible His word and has a vested interest in keeping it accurate, this would have required a massive conspiracy involving thousands of eyewitnesses beginning from the time of the Lord’s life. All the New Testament was written within 60 years of His death when there were still enough people alive who had witnessed events to call attention to any errors. There are 5,686 ancient Greek manuscripts in existence today for the New Testament, thousands more than for any other ancient text. Because the copies are so numerous, they can be cross-checked for accuracy. This process has determined the internal consistency of New Testament documents to be about 99.5% textually pure. In addition, there are over 19,000 ancient copies in the Syriac, Latin, Coptic, and Aramaic languages. The total supporting New Testament manuscript base is over 24,000. The Bible is the most thoroughly authenticated book in history.
The likelihood that any person or group could have been rich or powerful enough to pull off something like you suggest is so small as to be practically non-existent.
