I can only imagine how horrified the Jews must have been when they heard Jesus speak of "eating the flesh of the Son of Man and drinking His blood." We know it has a spiritual meaning, but most of those hearing these words of Jesus had no clue that He was not talking literally.
John 6:53-56 - "Jesus, therefore, said unto them—Verily, verily, I say unto you—Except ye eat the flesh of the Son of Man, and drink his blood, ye have not life within yourselves .He that feedeth upon my flesh, and drinketh my blood, hath life age-abiding, and, I, will raise him up at the last day; For, my flesh is true food, and my blood is true drink; He that feedeth upon my flesh, and drinketh my blood, in me abideth, and I in him.
John 6:60-61 - "Many of his disciples, therefore, when they heard said—
Hard is this discourse,—Who can, thereunto, hearken? But Jesus, knowing within himself that his disciples were murmuring concerning this, said unto them—
Doth this cause you, to stumble?
I believe that even common sense prevails on some things like eating crab, lobsters, snakes, octopus, etc.
It is repulsive and not created by God for human consumption, IMO.
BTW microlink, crab meat is one of my favorites. MmMm good!
