Did Jesus abolish the Law or not?

Matthew 5:17 and Ephesians 2:14-15

1. No. (Matt. 5:17), "Do not think that I came to abolish the Law or the Prophets; I did not come to abolish, but to fulfill."
2. Yes. (Eph. 2:14-15), "For He Himself is our peace, who made both groups into one, and broke down the barrier of the dividing wall, 15 by abolishing in His flesh the enmity, which is the Law of commandments contained in ordinances, that in Himself He might make the two into one new man, thus establishing peace."

In Matthew 5:17 Jesus is speaking about the Old Testament principles and authority of rule and revelation.  When Jesus said that He came to fulfill the law, He came to establish it and demonstrate how it pointed to Him and how He would live it perfectly.

In Eph. 2:14-15, Paul is speaking about how the gentiles who were called the uncircumcision (v. 11), were separated from Christ (v. 12), but have now been brought near (to God) by the blood of Christ (v. 13). Jesus removed the requirement of having to follow the Law in order to please God, established justification by faith, and thereby united both Jew and Gentile into one group in Christ.  This is when Paul says in verse 15 that he abolished in his flesh the enmity which is the law of commandments in ordinances.  The Law was that which separated Jew from Gentile and since it has been fulfilled in Christ, it is no longer something that would separate Jew and Gentile.
