That's right. His words not mine.
Matthew 5:17-20 “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished. Therefore whoever relaxes one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever does them and teaches them will be called great in the kingdom of heaven. For I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.
So, do you eat the Passover? Do you eat pork? Do you offer sacrifices at the Temple?
The MORAL law is unchangeable. The Jewish RITUAL law could and did change.
The prohibition on drinking the blood of the victim existed for a certain reason—that the victim’s life belonged to God. That reason ceased to exist when the victim was no longer an animal, but Jesus himself. The life of Jesus belongs to US. He gave it to us.
He TELLS us that he has given us his life precisely by commanding that we drink his blood.
