I've learned much from my non-Catholic friends.

Sigh. My very very dearest friend was descended from the Germans and I am descended from the Jews. I said to him before he died, and I loved him so much, "Just think, At one time, your ancestors were killing my ancestors. He looked at me and said, "Blessed are the peacemakers." The grace is sufficient for me.

I am descended from the Jews.

What - you're not a Kerry man?!!:)

What would have happened to your ancestors in Egypt if instead of sacrificing and eating the Paschal lamb, as God had told them to, they simply ate lamb-shaped waifers as a symbol or "mere memorial" of a lamb? Would they not have woken up the next day to find all the First Born slaughtered? The priests of Israel would have been wiped out like the priests of Egypt.

As this lamb was only a type and foreshadowing of the True Lamb of God, His only-begotten First Born, then how much more in the New Covenant should you be renewing your covenant with God by attending the sacrifice and eating the Lamb?

The rabbi's who wrote the targums new that in the age to come only the toda sacrifice would remain - you need this - its all in your family history - if you've already accepted the baptismal fulfilment of crossing the Red Sea, you also need to accept the Eucharistic fulfilment of the Passover lamb.

If you look to your own roots you will find that no covenant is sealed or renewed without oath (sacramentum/shebah) or sacrifice. The Jewish prophets were anticipating the time when it would be here:

Mal 1:11 "For from the rising of the sun even to the going down, my name is great among the Gentiles, and in every place there is sacrifice, and there is offered to my name a clean oblation: for my name is great among the Gentiles, saith the Lord of hosts."

The Old Covenant sacrifices are not just worthless they are taken up and fulfilled in the New Covenant sacrifice of Christ that is the heart of the Mass:

Heb 10:25 "Not forsaking our assembly (ecclesia), as some are accustomed; but comforting one another, and so much the more as you see the day approaching.
26 For if we sin wilfully after having the knowledge of the truth, there is now left no SACRIFICE for sins,"

The Catholic Church was founded by and on Jews who understood both the difference and the continuity of the seven covenants and the role of sacrifice in our relationship with God:

Heb 13:9 "Be not led away with various and strange doctrines. For it is best that the heart be established with grace, not with meats; which have not profited those that walk in them.
10 We have an ALTAR, whereof they have no power to eat who serve the tabernacle."

It was for the Jews that Christ came first - your rightful place as God's first born is at the top of the table at the Wedding Banquet of the Lamb - you won't find it even understood never mind going on in any protestant church.
