We do not ignore this.Actually Jews time began with this exodus, “This month shall be unto you the beginning of months ,the first month of the year. Yet what better way to remember than to “go back in time”. Totally agree. However, the lamb and bread and wine Jews take today during Passover are not transubstantiated to be the same as the original elements of Passover. It is strictly a memorial, for s sign, for a token (Ex. 12:4,13:9,16) That is not say it is not a spiritual experience/remembrance. Actually was there any consecration prayer at first passover, like Lord I hope you find the blood on the door post acceptable, please pass me by?” I don’t think so for to ask is not taking the Lord’s command as a done deal in faith. It is (was) time to obey, not pray/consecrate. The Passover is not a sin offering, at least not directly. It was primarily to show obedience and faith in God’s deliverance. That is it was not for justification, for they were already a covenant people by circumcision and with and thru Abraham.
The Jews might have ended the immediacy of it. But we did not.
We hold that same transunstantiation now as they did
then. that is why we have both the old and new testaments
in every part of the Mass. It is also incidentally just
another reason we hold Mary in such high esteem- she
has been called our “bridge” between the old and
the new.
The answer to your original question though still
lies with the Mystical Body of Christ. The mystical,
that becomes for those moments of timelessness
immediate reality. We ARE at the Last Supper, we ARE
at the foot of the cross next to John while Mary receives the
dead body of her Son and we are there with Mary
of Clophas and the soldiers. We DO receive the
resurrected glorified Body of the Risen Christ.
That is the mystical “time warp” of transubstantiation,
the same time warp the Jews experienced then but
with a different Victim and a bridge to new life.
