Four Questions for the Lord's Supper

This Sunday in our discussion of the Last Supper and it's parallels with the Passover, we briefly considered the Jewish tradition of asking the "four questions" during the Passover meal. The questions and their answers are an interesting way to teach the history behind the annual event to the children at the table. Depending on who you ask, the questions are answered by either the elders at the table or by the children themselves. Later I posed the question, what would be our "four questions" about the Lord's Supper. Keep in mind that the purpose of asking the questions is to teach. They aren't simply questions that children might have, but rather questions that would be helpful for them to understand why we do what we do. So what would your "four questions" be?

I also wanted you to consider the idea of a Christian observation of a Passover Seder. I'll stop short of recommending that we all start observing Passover rituals. But, I do think it's an interesting idea and I'm curious whether any of you feel it would be right or wrong, helpful or futile. I know some of you have observed Passover and maybe could share your experience with the rest of us. If we were to celebrate Passover, what role would Christ have and how would we alter the traditional ritual to focus on Christ. Is this even necessary since we observe the Lord's Supper and it effectively takes the place of Passover for the Christian. I read about these folks who are finding the Passover to be enriching their faith but, they are meeting opposition in some curious places. Feel free to discuss in the comments.
