If the CO is refering to the account at John 6:51-71...
(John 6:53-56) 53 Accordingly Jesus said to them: "Most truly I say to YOU, Unless YOU eat the flesh of the Son of man and drink his blood, YOU have no life in yourselves. 54 He that feeds on my flesh and drinks my blood has everlasting life, and I shall resurrect him at the last day; 55 for my flesh is true food, and my blood is true drink. 56 He that feeds on my flesh and drinks my blood remains in union with me, and I in union with him.
There is no parallel account in any of the other gospels to this event, so we just have the word of one witness on this. Also, he used this strategy how many times to sift out the weak? Okay, so Jesus did this once, maybe. So, why has the FDS used this 'sifting strategy' about a dozen times with the word "generation" alone?
According to the Greatest Man book, two stories later, came this account...
(Matthew 15:21-31) 21 Leaving there, Jesus now withdrew into the parts of Tyre and Si´don. 22 And, look! a Phoe·ni´cian woman from those regions came out and cried aloud, saying: "Have mercy on me, Lord, Son of David. My daughter is badly demonized." ...28 Then Jesus said in reply to her: "O woman, great is your faith; let it happen to you as you wish." And her daughter was healed from that hour on.
29 Crossing country from there, Jesus next came near the sea of Gal´i·lee, and, after going up into the mountain, he was sitting there. 30 Then great crowds approached him, having along with them people that were lame, maimed, blind, dumb, and many otherwise, and they fairly threw them at his feet, and he cured them; 31 so that the crowd felt amazement as they saw the dumb speaking and the lame walking and the blind seeing, and they glorified the God of Israel.
Okay, so if the FDS has the authority to 'sift' like Jesus did, why can't they heal like Jesus did? And we don't need the 'spiritual' healing line. I think the real spiritual healing occurs at places like here at JWD.
