Jws pick and choose what Scriptures they will use. They are taught by stupid men and so they end up stupid too. Example they love James 1:26-27 faith with out works is worthless yet never read Ephesian 2:8-9 where it says the exact opposite.
About the eating of the bread and wine, every other Christian religion knows that Jesus was talking to everyone in the crowd at copernium when he said you have to eat my flesh to have life in you. The second group he talks about the other sheep is the gentiles, Christians know this as well.
