MITM,
True, Jesus was speaking in metaphors. This fact has no bearing on my comments. The last supper was a type of metaphor called an object lesson. Today’s observance is also an object lesson.
He was still talking to far more than just the 12. People left because they did not like what He said, not because it did not apply to them. In fact, their complaining shows they understood His words to be directed to them. Show me where it says they left because it did not apply to them.
I thought that the words in 1Cor are Jehovah’s. Are you saying that only the words in red can be trusted? Or, are you saying that the words in red are more the word’s of Jehovah than the words in black? Do you ignore everything after the Gospel of John? Are you saying that with the passing of the 12, nobody should have done it since?
