Yet, again, this sign at Cana comes right before the Feast of Passover, wherein the Lamb of Passover is consumed, and the blood of the lamb is the sign of covenant faithfulness.
Fourth, the wine offered by the “bridegroom” is considered to be the better wine, in this instance, and the previous wine was the lesser. In OT typology, the type is always a lesser sign of the truth to come. In this case, the wine that Christ offers, the sacrifice of His blood, is the better wine.
Moreover, take note, this wedding at Cana takes place on “the third day” (John 2:1). This is an allusion to the day of His resurrection, when His purifying sacrifice would be completed. These allusions are confirmed in the pages to follow.
First, after entering Jerusalem at the time of Passover, Jesus “cleanses the temple” by driving out the money changers and the merchants. He then prophesies His death and resurrection (on the third day) when He says “Destroy this temple, and in three days I will raise it up” (John 2:19). Note, He identifies the temple with His body. As we are His body, and He has just cleansed the temple, we ought to take this as a sign that it is by His power that we are cleansed.
Second, the following account with Nicodemus affirms the necessity of Baptism “of water and the spirit” (John 3:5). Later, after Jesus travel to Judea, John the Baptist identifies Jesus as the bridegroom (John 3:29).
After this, Jesus travels to Galilee and meets the Samaritan woman at the well. He tells her that whoever drinks of the water “that I will give him shall never thirst; but the water that I will give him shall become in him a fountain of water, springing up unto life everlasting” (John 4:14). If we understand that the water He offers, this life-giving water, is symbolized to us in the Cana miracle, then we will know that this water is the wine of self-sacrifice, His own blood shed on the Cross.
Skip ahead to Chapter 6, and we arrive at the second Passover Feast of His Ministry. Here, Jesus feeds the five thousand with five loaves and two fishes. When they collect the scraps, there’s no fish left, but there are 12 baskets of bread! (John 6:13). We understand the twelve tribes to be the foundation of the nation of Israel. Likewise, we understand the Twelve to be the foundation of the Church, the new Israel. Here, we may understand the twelve baskets filled with bread to be the abundance of the Lord filling the Church.
Yet, it is not just His abundance, but He, Himself, who fills the Church. For He says, “I am the bread of life. He who comes to me shall not hunger, and He who believes in me shall not thirst” (John 6:35, also John 6:48, 51). Note, He references His earlier teaching regarding the water that He gives when he says “shall not thirst.” Obviously, bread does not quench thirst. However, given the language He employs here, “I am the bread of life,” we ought to understand this also in light of His future teaching, “I am the true vine.”
And He gives this teaching a forceful interpretation. He says “Amen, amen, I say to you, unless you eat the flesh of the Son of Man, and drink His blood, you shall not have life in you” (John 6:54). This affirms the correlation between the water and wine. Previously, He said it was the water He would give that gave everlasting life. Now He says it is His blood. So, the water and the wine go hand-in-hand; a clear vision of the water and blood that flow from His side at the crucifixion.
Jesus doesn’t exchange one symbol for the other here. The bread is not one symbol, and His flesh another symbol. He is interpreting the symbol to the reality. The bread is His flesh; the water/wine is His blood. Bread/manna and wine are the types, the images pointing to a future truth. His flesh and blood are the truths.
And again, this teaching comes on the Feast of the Passover, wherein the lamb is slaughtered and consumed. It is a hard saying, indeed.
So, what about the Last Supper? In John 5:11, we see these words: “Jesus then took the loaves, and when he had given thanks, distributed them to those reclining…” This formula of “taking bread”, “giving thanks” and “distributing” is found in all three synoptic Gospels at the Last Supper account (Matthew 26:26, Mark 14:22, Luke 22:19). And, as John’s Gospel is understood to have been the later written, this formula should be understood to recall these Last Supper accounts. Moreover, in John 21:13, after the resurrection, it is by the breaking of bread that the Disciples recognize Him.
The symbolisms of the bread and wine, interpreted by the Lord to be His flesh and blood, are carried throughout the Gospels, and the signs and words of our Lord regarding these things always fall within the context of the Feast of the Passover. The opening context of these verses is announced by John the Baptist: Jesus is the Lamb of God, who takes away the sins of the world. Being within the context of the Passover, the sign of our covenant fidelity to Our Lord in His new covenant would consist in two things: first, the sign of His blood in our lives, which is marked by self-sacrifice for our friends. This is how we fulfill His command to love as He loved us. Second, the consumption of Him, who is the Lamb of Passover. This is the second sign of covenantal fidelity.
Yes, He is the Lamb of Atonement, but He is also the Lamb of Passover. The Last Supper is also set in the context of the Passover, and is tied to the John 6 passage by the symbolism of bread and water/wine, tied up throughout the Gospel, as well as His formulaic act of breaking, blessing/giving thanks, and distributing.
At least… those are my thoughts.
