the teaching is an interpretation.
How many people read the ancient languages of the Bible and understand its poetic wording and the meaning behind it. Everything in the Bible is translation and interpretation not only the JW BT teachings. But JW claim that they are guided by God ( so do all religions but that is not the issue here) in the spiritual food ( teachings ) JW provide. If you don’t believe that, you are not JW. What TD is saying is that God is not behind the BT teaching but it is only human belief subject to error. Obviously, God punishes such presumptuousness but we haven't seen that. What a JW considers is God does not want humans to consume blood. That is what JW believe.
