Peace Sun Tzu,
"Do not think that I have come to abolish the Law (Torah) or the Prophets (Nevi'im); 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 of a pen, will by any means disappear from the Law; until everything is accomplished. Anyone who breaks 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 practices and teaches these commands will be called great in the kingdom of heaven. For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the Law, you will certainly not enter the Kingdom of Heaven." Matthew 5:17-20
If you bothered to read this correctly you'd realize the word "fulfill"
Jesus came to fulfill the Law, meaning the prophecies with in the Law.
Jesus summarized the Law, dropping most of it's human precepts.
Jesus says anyone who breaks the least of the Law that He teaches will be the least in Heaven. Jesus calls us to be more righteous than the adherants of the Torah Laws who follow human precepts and often forget God. Jesus's Law really focuses us of loving God and loving one another; this is really how God wants us to be.
Now since you're misinterpreting this passage, so you're entire argument against Paul is void.
