The Last Supper was both the celebration and fulfillment of the Passover, a solemn ritual inaugurated by Moses in Egypt the night before the Exodus. And yet it was the First Mass which anticipated and was indivisibly connected to the Crucifixion and the Resurrection.
In fact, our Lord offered his resurrected flesh -- in Eucharistic form -- to the Apostles before the Resurrection. To say it another way, the fruit from the tree was given and consumed three days before the tree existed in time. Indeed, the Last Supper in the Upper Room on Holy Thursday, Our Lord’s death on the Cross and the Resurrection was the New Passover whole and entire.
Our Lord began the New Passover as the High Priest according to the order of Melchizedek by using bread and wine in order to sacrificially offer himself in ritual (so that others could share in it throughout the ages). He then consummated it and confirmed it by personally laying down his life as act of love to the Father for the salvation of mankind; this, he did as the Passover Lamb whose blood would be applied to the doorpost of every soul who approached the altar of God. And like the smoke of incense ascending upward, he animated his deceased body in the tomb in order to raise it up, eventually taking it to heaven. Truly, he was a priest, victim and a holocaust.
As man, Jesus Christ could offer his body and blood as a victim in time and in the space of the Upper Room. But as God, he was both in heaven and on earth. Perhaps we seldom consider that the Holy Sacrifice of the First Mass occurred both on Holy Thursday and in eternity. As such, it could be united to every single Mass that was ever to be celebrated until the end of time. This includes, of course, every Mass that we assist at.
