According to the new testament, the body of Jesus is the offering for our sins (Hebrews 10:10). Jesus said he would give his flesh for the life of the world. ~ John 6:51-57
Under the old testament the sacrifices which foreshadowed Jesus had to be unblemished and holy.
Jesus redeemed us with his precious blood as of a lamb without spot or blemish (1 Peter 1:18-20). If Jesus’ body had not been holy and without sin, his blood could not have been holy. The blood of Jesus is holy because Jesus’ body was holy and because he was and is holy.
This is precisely why Jesus’ body did not decay in the tomb. The apostle Peter, referring to the body of Jesus in the tomb, said death could not hold Jesus because God would not allow his holy one to see corruption (Acts 2:27). Again, this is a reference to the body of Jesus in the tomb.
Jesus’ body was the fulfillment of the unleavened bread eaten by the people of Israel as they were delivered by the blood of the lamb. ~ Exodus 12
At the last supper, Jesus said to his disciples: “this is my body broken for you, and this is my blood shed for you.” ~ Luke 22:19-20
This memorial known as holy communion was given to us as an ordinance to observe until the coming of the Lord. In 1 Corinthians 11, Paul told the Corinthians that some of them were sick and some of them had died because they did not discern the body of the Lord. They were approaching the Lord’s table with irreverence.
Just as Jesus’ spiritual body (the church) is called to be holy, so his physical body was and is holy. Jesus was without sin in every respect.
Any concept that claims Jesus had sin in his body goes against the whole counsel of scripture and is based on a very flawed understanding the scriptures. Jesus is, was, and always will be holy.
