This thread attempts to clear up certain misconceptions that Jesus appeared to counter and dismiss the Old Testament law, and that Jesus had nothing to do with the Old Testament God who gave these Laws. A lot of my points are taken from another thread that I had participated in recently.

1. Jesus said the Law is to remain “till heaven and earth disappear.” 
Christians often quote Jesus’ famous words “let he without sin cast the first stone” and claim it as “proof” that the Israelite Laws calling for harsh punishments were done away with by Jesus. The truth is that Jesus, using God-given authority and discretion, spared the adulteress to remind the hypocritical Pharisees of their own sins. Jesus turned the tables on the Pharisees only because he saw them as a bigger moral problem than the adulteress. It was NOT because he taught that the Law was done with as Christians claim. On the contrary, Jesus declared that the law was to remain until heaven and earth disappear.

“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. I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke or a pen, will by any means disappear from the Law until everything is accomplished. – Matthew 5:17-18 

Don’t tell me everything was accomplished when Jesus was nailed to the cross. Jesus said nothing about this either on the way to the cross, or after his resurrection. The idea that the law was done with is a Christian concoction. As we can see, heaven and earth are still around, and so every part of the law remains – according to Jesus.

2. Jesus constantly referred to the Old Testament God, Law and prophets. 
Christians dance around the issue of the Law by claiming that the “Law” spoken of by Jesus was really not the same as the “Law” mentioned in the Old Testament, but something else. I’ve also come across some “Christians” who claim that the God of the OT was different from the One who Jesus called God (I’ll address this point later.)

The truth is that there is nothing to prove that there were actually 2 sets of laws mentioned in the Bible… a harsh OT law and a softer law that Jesus referred to, as some people calling themselves “Christians” claim. There was only one Law, given by God to Moses, who brought it to the Israelites, which Jesus referred to. Therfore, it means Jesus also kept referring to the OT God who gave the law to Moses and spoke to the prophets.

It is also made obvious that Jesus was referring to the Law mentioned in the Old Testament when he said “Do not think that I have come to abolish the Law or the Prophets. If Jesus was talking about the prophets of the OT, then its obvious that he was talking about the OT Law as well. It’s simply ridiculous to claim he was referring to the OT Prophets but spoke of some other Law. Then again, I wouldn’t be surprised if some Christians actually go on to claim that very thing.

Then we have Jesus doing the following :
– Jesus referred to the 10 commandments and the law (given to Moses by the OT God)
– Jesus referred to the custom of offering gifts on the altar (according to OT law)
– Jesus referred to Isaiah, Noah, Abraham, Jonah, Moses etc. (prophets who the OT God spoke to)
– Jesus revered the temple where Israelites worshiped (the OT God)
– Jesus acknowledged the Pharisees authority (who followed the OT law and sat in the seat of Moses)
– Jesus ate the Passover meal (food prepared according to the OT law)

So, Christians who claim Jesus’ God was not the God of the OT, why did Jesus go around referring to OT prophets who the OT God spoke to? Why did Jesus refer to OT laws and custom? We see all those references to things we know from OT because Jesus operated within the existing Israelite Laws and customs. It is simply impossible to separate Jesus from the Old Testament God, the prophets, the laws and practices. “Christians” who try and do so are living in their own imagination.

(* I don’t like using the term “the OT God”, but I am just using it here to make a point that “the OT God” was the God of Jesus)

3. Shocker : Jesus actually acknowledged the Pharisees authority. 
“The scribes and the Pharisees have seated themselves in the chair of Moses; therefore all that they tell you, do and observe, but do not do according to their deeds; for they say things and do not do them. – Matthew 23:2-3 

Jesus is known to have severely criticized the Pharisees calling them white-washed graves, hypocrites and what not. One would imagine that Jesus would have instructed people to rebel against these wicked Pharisees.

Yet, amazingly Jesus acknowledged the authority of the Pharisees, and instructed people to “do and observe” as the Pharisees said. The big question is, was Jesus being a hypocrite for opposing the Pharisees while at the same time, instructing people to do and observe as they said? Or was there a deeper reason as to why he taught people to do and observe as the Pharisees said?

Jesus called out the Pharisees on their hypocrisy, but even that was no reason for Jesus to dismiss the very Law that the Pharisees were authorities on. Much like how your country’s law is more important than corrupt authorities, the Law of God was more important to Jesus than the human authorities. Jesus obviously respected Moses and the Law, and thought people to follow the Law, with a few tweaks here and there. Which is why he said the law was to remain, and even went on to acknowledge the authority of Pharisees, who were (unfortunately) seated in Moses’ chair, i.e- as authorities on Israelite laws. Jesus instructed people to do as the Pharisees say. Nowhere did Jesus ever tell them to “do as they say, except the nasty bits”.

We also know that the Pharisees were known to sentence people to death by stoning according to the Law. So if Jesus wanted people to do as the Pharisees said and if the Pharisees were obsessed with the Law… and if Jesus never mentioned anything about certain parts of the law not applying anymore….it can safely be concluded that Jesus acknowledged even the laws that required stoning.
