No disrespect taken.
I would encourage you to listen to Scott Hahn’s talk “Understanding the Eucharist.” You can get the CD at www.lighthousecatholicmedia.com. Heck, if you e-mail me your address I’ll send it to you for free.
Dr. Hahn is a former protestant minister (at one point, vehemently anti-Catholic) who is now a leading Catholic apologist.
Anyway, he does a way better job than I could ever do explaining the connection between the Jewish Passover meal and the Last Supper (which was, of course, a Passover meal). As I’m sure you know, the New Testament is a fulfillment of the Old and there are tons of connections between the two. Very briefly, in the Old Testament, the Jews were required to not only sacrifice a lamb, but also eat its flesh. Christ is often times referred to as the “lamb of God” and he requires us to eat His flesh (the Eucharist), just as the Jews were required to eat the flesh of the lamb at the Passover meal. (See the connection?) Of course, Christ’s death on the cross was a once and for all thing, and we Catholics are not “recrucifying” Him at every Mass, as is often misrepresented by anti-Catholics. We are simply re-presenting the sacrifice. To complete what Jesus commanded, we have to eat that re-presented sacrifice:
John 6:54: Then Jesus said to them: Amen, amen I say unto you: Except you eat the flesh of the Son of man, and drink his blood, you shall not have life in you.
He also has a book called “The Lamb’s Supper” which describes the Mass and details its connection to the book of Revelation (I think). I haven’t read it yet, but from the title I would guess he might get into this same thing in that.
Rosalyn Moss is also an excellent one to explain this connection. She is a former Jew who converted to Evangelical Christianity and is now Catholic. I went to one of her talks a couple years ago and she did a fabulous job explaining this connection, as well.
Anyway, if you listen to Dr. Hahn’s talk, you will understand what I’m talking about when I say that it is the understanding of the history of the Passover meal that makes sense of the Last Supper and what Christ was doing there when He instituted the Eucharist.
