It's hard to take that site seriously, when it has a picture of Charles Manson as Barnabas.
It is full of assumptions, and chooses the Bible as a historical text where it is useful for the intended purpose of the site, and then at the same time says it is manufactured. The site uses counter syncretistic reasoning where symbolic images mimic and reflect each other as evidence. When the authors of this site don't take things seriously, it is not difficult to not take them seriously.
