Christ fulfilled all of the requirements of the Law, the moral, sacrificial and ceremonial aspects of the Law of God all find their fulfillment in Him.
As for human sacrifice- why does the Law say that when a man hangs on a tree he is accursed of God, and that in his death the curse on the land is removed, provided they take him down before sundown? Why did Abraham sacrifice Isaac to God? The only problem with Human sacrifice, is that other than Christ, there are no human beings without Spot and blemish. Read Isaiah 53 and then tell ne there is no human sacrifice. Surely he has born our griefs and carried our sorrows,...he has borne our transgressions and iniquity, and the chastisement that brought our peace fell upon Him...
Isaiah 53 refers to Israel, not Jesus.
Again, what did Jesus fulfill? Did he bring peace on Earth? Hardly. If anything his name was used by medieval Christians to justify the brutal treatment of the Jews. After all, the Christian Bible is full of Jew-hatred. Did he not call the Jews the “Spawn of Satan” and that they were “Children of the Devil”?
He also told his followers to violate the Sabbath among other things. He discouraged marriage. He told his followers to eat whatever they wanted which is in direct violation of Jewish Law. He himself was a sinner.
