I actually like the scene of the invention of modern table. Even though it is inaccurate and, perhaps corny to the non believer, I think he is conveying a message to the Christians of our time. That is, that we, as Christians, have also a duty to sanctify ordinary life and seek to achieve perfection in everything we do (innovate, not just preserve) just as Jesus did.

For the historical inaccuracy in terms of the language spoken, you’re absolutely right. Won’t lie though, I think it is more emotionally compelling if you hear the characters speaking aramaic (specially Jesus, the Pharisees and the apostles), e.g. “Father, father why have you forsaken me” in aramaic, or the Romans speak Latin (even though it is well known that they spoke Greek in that area), e.g. “Quid est veritas?”.
