A Messianic Jewish Rabbi sort of bloke held such a service/Sedar in Israel, with our tour group, IIRC . . . I am certain he did in San Diego but I think he did in Israel as well. Very meaningful.
The Passover meal was a foreshadowing of Christ, but apparently, most Jews didn’t really get it. There was a lot of confusion about the Messiah then as they obviously didn’t expect Jesus to be what He was otherwise they would have recognized Him and accepted Him.
His statements of *This is my body/blood.* is no different in nature than the rest of the times He explained parables to the disciples. He told them spiritual truth using symbolism and then had to explain what that symbolism actually represented because they still missed it.
