For just as the body is a unity and yet has many parts, and all the parts, though many, form [only] one body, so it is with Christ (the Messiah, the Anointed One). For by [means of the personal agency of] one [Holy] Spirit we were all, whether Jews or Greeks, slaves or free, baptized [and by baptism united together] into one body, and all made to drink of one [Holy] Spirit.
1 Corinthians 12:12-13 [AMP]
May grace (God's unmerited favor) and spiritual peace [which means peace with God and harmony, unity, and undisturbedness] be yours from God our Father and from the Lord Jesus Christ.
Ephesians 1:2 [AMP]
For He is [Himself] our peace (our bond of unity and harmony). He has made us both [Jew and Gentile] one [body], and has broken down (destroyed, abolished) the hostile dividing wall between us
Ephesians 2:14 [AMP]
