Ephesians 2:14-15 -- Christ ”abolishes” the Law!

Ephesians 2:14-15

The English Standard Version translates that Christ "abolished" the Mosaic Law in order to tear down the wall of hostility that separates Gentiles from Israel.  If true, how are we to understand it?  What does Scripture teach?  And what about Jesus's statement in Matthew 5:17 that He did not come to destroy the law?
