Which law was the law given by Moses in John 1:17, the law of commandments Christ abolished in Ephesians 2:15?

Your buddy Jesus didn't abolish anything. You're referring to text written by a Hellenize Jew long after Jesus (how is it that he has a Greek name?) was dead. Written by a guy who'd never met your saviour. Yet you believe that this fellow speaks for your demi-god. Interesting.
