Except for one verse that they DEMAND that everyone has to take literally when they don’t even take the rest of the chapter literally.
Picking and choosing whether to take something literally or figuratively on a verse by verse basis within one passage is poor Bible exposition, to say the very least.
It’s a mishandling of God’s word and smacks of dishonesty. There needs to be consistency because who’s to decide from one verse to the next if the speaker or writer meant it to be literal or figurative. You can;t make that decision based on preconceived personal preferences.
Either it’s all figurative, or it’s all literal, and we see that John 6 does not work when it’s all literal.
It’s twisting of scripture to fit the pagan “eating of their gods”.
