as usual you're just playing word games, anything in attempt to discredit the word of God and uphold the words of men because you believe the words of the men of the RCC instead of those of God. the NT didn't start until His death, not a meal prior to it.Maybe the baby isn't born until the birth is complete, but does that mean there is no baby when it's only partially born?
and I do believe scripture regarding that has already been posted by someone here. that you choose not to believe God's word is a major problem for you.
those with Him at the last supper still did not know what would be happening to Him in the coming hours. They did not believe they were eating His body or drinking His blood. They were Jews still in OT time and held to Jewish law.
and yet we know that Peter did fall away, he did deny Jesus - 3x ! those who know Him and believe His word do know that. according to your own post you don't know that.From Matthew:
 Then Jesus said to them, "You will all fall away because of me this night; for it is written, `I will strike the shepherd, and the sheep of the flock will be scattered.'
 But after I am raised up, I will go before you to Galilee."
 Peter declared to him, "Though they all fall away because of you, I will never fall away."
 Jesus said to him, "Truly, I say to you, this very night, before the cock crows, you will deny me three times."
 Peter said to him, "Even if I must die with you, I will not deny you." And so said all the disciples.
Peter said a lot of things - like that he wouldn't deny Him, but he did just that 3x. so obviously Peter didn't know his own weakness - but Jesus did know it.From Mark:
 for he was teaching his disciples, saying to them, "The Son of man will be delivered into the hands of men, and they will kill him; and when he is killed, after three days he will rise."
 But they did not understand the saying, and they were afraid to ask him.
They did not understand what Jesus was saying in vs 31.
here's Luke 18 -
31 Then he took unto him the twelve, and said unto them, Behold, we go up to Jerusalem, and all things that are written by the prophets concerning the Son of man shall be accomplished.
32 For he shall be delivered unto the Gentiles, and shall be mocked, and spitefully entreated, and spitted on:
33 And they shall scourge him, and put him to death: and the third day he shall rise again.
34 And they understood none of these things: and this saying was hid from them, neither knew they the things which were spoken.
those words (in God's word) are just 'some indications' to you that they didn't understand what He said?
It states clearly that they did not understand what He was saying.
