And that he might reconcile both unto God; another end of Christ's abolishing the ceremonial law, viz. that he might reconcile both Jew and Gentile (all the elect together) unto God: and in this respect especially he is our peace.

Of this enmity the ceremonial law was a witness, Colossians 2:14, as well as a sign of that between Jew and Gentile.
