Sorry, but no. The body of Christ imagery is not just in Ephesians, but first and most importantly in I Corinthians 12, especially vss. 12-13 and 27: "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. For in one Spirit we were all baptized into one body—Jews or Greeks, slaves or free—and all were made to drink of one Spirit." And "Now you are the body of Christ and individually members of it." (ESV)
