There was a jar filled with common wine. They stuck a sponge soaked in this wine on some hyssop and raised it to his lips. When Jesus took the wine, he said: “It is finished.”John 19:29-30
The New Covenant is now set. What began Thursday evening as a Seder meal that seemed to be interrupted just when they would have drunk from the cup of consummation is now revealed to be the holy sacrifice of the unblemished lamb, the Lamb of God. Thursday evening, Jesus told his disciples that he would not drink from the fruit of the vine until the kingdom of God comes.
By accepting a bit of sour wine, Jesus is completing the new Passover sacrifice. Where the old Passover freed the Hebrews from slavery in Egypt, the new sacrifice has freed everyone from slavery to sin and death. Those who are marked with the blood of the Lamb through baptism and faith in Christ are freed to enter into the kingdom of God.
The Paschal victim is also the Paschal priest. He offered the perfect sacrifice: Himself. He, who was without sin, took upon himself all our sins. In dying upon the cross, Jesus paid the price that we cannot pay.
The Seder meal was a liturgical memorial of the Passover. The food, the readings, the vestments, and the instructions on how to sit, were all prescribed and unchanging. The new Passover meal is the holy sacrifice of the Mass. More than a memorial meal, it is a mysterious participation in the sacrifice at Calvary.
Jesus has said, “it is finished.” He has drunk from the cup of consummation. He is about to go to his Heavenly Father. He has completed his earthly ministry, and through his sacrifice, he has transformed the Cross from an instrument of torture and death to the means of obtaining eternal life.
Faithful cross! above all other,
One and only noble tree!
None in foliage, none in blossom,
None in fruit thy peer may be;
Sweet the wood and sweet the iron!
And your load, most sweet is he.
