No, I don't have any incidents of mass suicides in ancient times ... I'm not even sure how this relates to the topic at hand ... that the DaVinci Code & the Bible are just two books.
Either could be right, or neither.
Is the Holy Grail a cup or Jesus' progeny or just a myth? No idea ... but books that weave a fun plot around it's existence are great entertainment.
My entire point is that Dan Brown's version of the Christian history is just as plausible as the Bible's.
If you don't think so ... why not?
According to Dan Brown, nobody thought Jesus is God until the Council of Nicea. According to the Bible, the early Christian believed that the Word was with God, and was God, and that the Word was made flesh, and dwelt among us, and we beheld His glory, as of the Only Begotten of the Father.
Now who is in a better position to know what early Christians believed? Dan Brown? Or the Apostle John?
