Read 1 Corinthians 12:12 Using Other Translations
For as the body is one, and hath many members, and all the members of that one body, being many, are one body: so also is Christ.
For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ.
The human body has many parts, but the many parts make up one whole body. So it is with the body of Christ.
