Ephesians 2:14
"For He Himself is our peace, who made both [groups into] one and broke down the barrier of the dividing wall,"
Christ "Creates in Himself" a New Humanity to Make Peace
Christ is said to be 'created' because He unites all of humanity within His own body, creating a new, peaceful humanity in Himself.
And that this is the sense of the Scriptures, we may learn from the Apostle, who says in Ephesians, 'Having broken down the middle wall of partition between us, having abolished in His flesh the enmity, even the law of commandments contained in ordinances, to create in Himself of two one new man, so making peace.' But if in Him the two are created, and these are in His body, reasonably then, bearing the two in Himself, He is as if Himself created; for those who were created in Himself He made one, and He was in them, as they.
