Chapter 6 of the Gospel of St. John is where our Lord begins His teaching on the Body and Blood (verse 51), “I am the living bread which came down from heaven: if any man eat of this bread, he shall live forever: and the bread that I will give is my flesh, which I will give for the life of the world.” It is this earlier feeding of the five thousand, with five loaves and two fishes that will become in John’s gospel the foundation of this teaching. But it is not something that is new to Scripture.
Jesus the “Christ” is the anointed one
The Apostle’s and Father’s highlight the spiritual meaning and underlying principles found hidden within what was written. It should be pointed out that the Church does not historically dispute the events recorded within all of Scripture, as some began to do during the reformation. The father’s, looking through the lens of apostolic teaching, examined Scripture from an allegoric perspective, that is, they understood the spiritual meaning had to be worked for.
It is possible to hold the Bible at face value, and also glean from it a profound meaning that can only be understood through the unction of the Holy Spirit. Jesus asked, “whom say ye that I am? And Simon Peter answered and said, thou art the Christ, the Son of the living God. And Jesus answered and said unto him, blessed are thou, Simon Bar-Jonah: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven” (Matthew 16:15-17).
Old-Testament symbolism using bread
Remember there are two Old-Testament instances where bread is used and given to God’s people. The first is “Manna,” meaning “What is it.” Manna was given to the people of God while they were traversing the wilderness on their journey to the Promised Land. For 40 years the manna appeared, and people were sustained by it. The wilderness is where we await the crossing over into the Promised Land, for us that is either the Second Coming or physical death whatever comes first (allegory).
The second is the within the sacrificial system of the Law of Moses. The reading here is super dry, repetitive and tedious. But it is within its dry, repetitive, and tedious nature that the most powerful revelation is born.
When scripture is boring and repetitive pay attention, it is about to reveal something to you.
The law prescribes the ministry of the anointed one, the “Christ.” Each infraction of the law is dealt with through sacrifice based upon its category. Each category prescribes a certain innovation to the ritual (for the purpose of time I will not get into the details). But in all cases of sin the penitent would bring to the tabernacle several offerings, these outward offerings were to be vicarious offerings for the offending member of the community.
The Israelite would bring the prescribed animal: bull, lamb or goat, and also a measure (an ephah) of fine wheat flour. He would wash in the brazen laver, then present his animal sacrifice at the altar of burnt offering, where he would lay his hands upon the victim, confessing his sins before the priest. The victim would then be drained of blood in the prescribed way, quartered, and laid flat upon the alter to be consumed by the fire.
Then, the priest would take from the measure of fine wheat flour a handful of wheat, a handful of oil, and handful of incense and throw it upon the fire as well as a thank offering, called a Eucharist in Greek. The remainder of the fine wheat flour was now given to the high priest and became a part of his reserve. He would later make the flour into cakes to be consumed only by his immediate family. No one else was entitled to this.
In some cases, the fine wheat flour was made into cakes beforehand and the offerer would present the cake to be burned upon the altar with the offering. They offered bread in much the same manner as we do today. But with each sacrificial victim, the fine flour was offered as a thank offering unto the Lord, and the remainder of the flour was given to the priests.
The overall process involved a ritual “wave” offering, which was done for certain types of atonement. The wave offering, according to the Jewish Mishna, would involve the offerer guided by the priest waving the offering before God at right angles. One movement was known as a “heave” and the other a “wave.” This was done with both a portion of the victim, and the thank offering, then the thank offering would be consumed by the offerer with a portion of the victim.
From the Exodus to the feeding of the five thousand to today
So what does this have to do with today’s gospel lesson? One commentator summarizes it as like this: The feeding of the five thousand “parallels the story of the Passover and Exodus of Israel from Egypt in several important ways.
(1) In the Exodus account, God first performed His signs against Pharaoh, then gave instructions on how to be saved at the time of the Passover. In this passage, the multitudes follow Christ because of His signs, and this too takes place at Passover (verse 4).
(2) In the Exodus, the Jews were said to eat unleavened bread because they were hastily driven out of Egypt and had brought no provision for themselves. Here, Jesus feeds the multitudes with earthly bread because they had brought no provisions, having rushed out to see him.
(3) In the Exodus, Moses leads the people across the Red Sea, walking on dry ground in the midst of the water. Here, Christ sends His disciples across the sea and then walks on the sea as if it were dry ground.
(4) In the Exodus, God fed His people manna and gave them drink from a miraculous water source. Here, Christ declares Himself to be true food and drink, the true bread that has come down from heaven.
These parallels demonstrate that Christ our God is the fulfillment of the Old Testament law, and that the breaking of His body and the shedding of His blood, which free mankind from the slavery of sin, fulfills the sacrifice of the Passover lambs, which brought the people out of slavery into the Promised Land.” 
The breaking of the loaves prefigures the Eucharist. He took the loaves, gave thanks and distributed them. Ultimately, this deliberate action would set the stage for His teaching at the Last Supper, when “he took bread, and gave thanks, and brake it, and gave unto them, saying, this is my body which is given for you: this do in remembrance of me.” (Luke 22:19)
We bring a sacrifice of praise and thanks
What all this points to is that Jesus is the Christ, the anointed one. He came as a sacrificial offering for the sins of the world that through Him we may have life. He is both priest and victim. We, as His adopted family, are entitled to His portion of holy bread and are required to give thanks to Him, it is our “bounden-duty and service.”
Just as the penitent brings his sacrifice with confession and offers his fine wheat flour as a thank offering so Christ, our Passover, has given himself for us. But now He requires that we partake of His sacrifice—the Eucharist—and through the thank offering which we ourselves bring, here, today. This is true worship, and a fulfillment of the Law through Jesus Christ.
