I thought the Brant Pitre book was/is excellent (one of the few that really get into the Jewish roots of our faith in such a powerful way) and I highly recommend it for anyone interested in the topic.
I made the point about John 6:66 on the journey home show because its struck me as a powerful coincidence (if one believes in co-incidence - candidly, I’m not a huge believer in “co-incidence”) that the very verse which talks about the disciples walking away from Jesus over the inability to accept the teaching that we must consume His flesh (the Eucharist) bore the number commonly associated with Satan. That said, I do agree with the responses which note the number system of verses in the bible occurred much later (although God does work in mysterious ways at times

).
Interstingly - today, it is disagreement over the Eucharist (whether it is really Jesus’ flesh and blood) which divides the body of Christ (Catholic and Protestant). To me, its somewhat analagous to the serpant’s statement to Eve in the garden of eden when discussing the forbidden fruit (you “wont” die if you eat it) - “its not really Jesus’s flesh and blood”. If the Eucharist was given to us by Jesus to strengthen us through this utlimate sacrament, what better tool would Satan have than to convince Christian’s it is not really Jesus’ blood and body?
Ultimately, it was the belief in, and spiritual drawing towards, the Eucharist, which led me to cross the Tiber (having come to faith in an evangelical setting).
