Obviously He did since He said it:
[19] And taking bread, he gave thanks, and brake; and gave to them, saying: This is my body, which is given for you. Do this for a commemoration of me. [20] In like manner the chalice also, after he had supped, saying: This is the chalice, the new testament in my blood, which shall be shed for you. (Luke 22:19-20)
I believe it. You believe Luther and other charlatans.
He also said,
“I am the vine, you are the branches.” Which does not mean He was made of wood.
He also said,
“I am the door,” obviously he is not made of wood and hinges.
Jesus often used metaphor and simile.
When He is standing there serving bread and wine, and says, “This is my body, this is my blood,” it is an obvious case. His blood and flesh are on his frame at the time, and it is apparent to all present.
