Well, actually here in Mark it does.
Mark 14:22 And as they were eating, he took bread, and after blessing it broke it and gave it to them, and said, “Take; this is my body.” 23And he took a cup, and when he had given thanks he gave it to them, and they all drank of it. 24And he said to them, “This is my blood of the covenant, which is poured out for many. 25Truly, I say to you, I will not drink again of the fruit of the vine until that day when I drink it new in the kingdom of God.”
It says *all* therefore Jesus, being with them, drank it as well.
That still leaves the questions....
If it was His blood in the cup,
Did Jesus actually drink His own blood and break the Law He said He came to fulfill?
Did the disciples drink it thinking that they were drinking blood?
If they thought it was blood, would they have drank it?
Would Jesus have commanded them to drink it in violation of the Law?
The only way this works if it was still wine and the disciples understood it to be such and the ceremony was one of remembrance, just as the Passover meal was of the first Passover.
I stand corrected.
The blood was offered to the disciples. Jesus had no reason to drink his own blood, hello! he didn't have to do that in memory of him, LOL.
Would Jesus have commanded them to drink it in violation of the Law?
He told them to violate the Law in other instances.
The only way this works if it was still wine and the disciples understood it to be such and the ceremony was one of remembrance, just as the Passover meal was of the first Passover
First Passover, like any subsequent Passover is a real meal, not just the remembering of the lamb. They eat the same thing they believe Passover Jews ate. Besides, the comparison is moot; the Passover sacrifice was not a sin sacrifice. For sin sacrifice, a goat (instead of a lamb) is used on Yom Kippur, and the goat is usually not killed.
