All in Bread

What do you think of during communion? What was happening on that day of the first communion in which Jesus offered the bread of His body and the cup of His blood to the disciples? On that day they were celebrating the Passover feast, eating the Seder meal, and it has a certain order and meaning to all of its parts. Every movement, every food, each cup of wine has meaning and timing. When did Jesus offer Himself to His disciples? What did it imply?
