In brief response, the linked article by Patton appears at first glance to be a textbook case of taking a viewpoint and finding scripture to fit it. Patton’s case boils down to three scriptural citations which he argues demonstrate that Jesus was quite content leaving those around him in confusion. In the first citation, concerning Jesus’s pronouncement about rebuilding the temple, John immediately provides a “voiceover” to direct the reader’s attention to understand the symbolism. In the second, concerning being born again, not only does a literal reading present an absolute utter impossibility (man can’t reenter the womb, so this is clearly symbolic, whereas God can do whatever He darn well pleases), but Jesus goes on to provide at least a little more explanation (one must be born of water and of spirit). The third example, concerning Jesus’s “food that you do not know about,” Jesus corrects the disciples’ misunderstanding in the very next verse.
So it appears that Patton has noted three distinct outcomes, none of which support his opinion: (1) Jesus says something symbolic which the author (here, John) explains, (2) Jesus says something that the Bible elsewhere gives further detail, and (3) Jesus leaves no one in confusion because he immediately corrects the misunderstanding.
Not so in John 6. There Jesus, speaking sort of symbolically, calls himself the Bread of Life. He didn’t mean he was at that moment actually bread, so we can safely say he was speaking symbolically, in a sense. It seems to me that the discussion really changes when He says that the bread that he “will” give for the life of the world is his flesh. At this point it seems to become more literal and less symbolic. Jesus doesn’t then hear the objections and correct a misunderstanding. John doesn’t give us a voiceover explaining what Jesus meant. And the Bible doesn’t otherwise suggest that this was referred to only symbolically. Rather John continues, quoting Jesus, as Jesus for the first time goes further and says that one must eat his flesh and drink his blood to receive eternal life. He then explains that his flesh is real food and his blood is real drink. Then as John continues to echo the refrain about eating flesh and drinking blood, he changes the wording a bit to use a word meaning roughly to “gnaw” or “tear” like we would with meat. Jesus passively sit by and allow those listening to be confused and misunderstand his comments, he bolsters them by indicating that they correctly understood, despite the difficulty of accepting this teaching.
Ok, so this wasn’t actually brief . . .
