When people speak of the bride of Christ (the church) maybe they should be saying that “she has a nice body” – for we are to be Jesus in this world. Paul works through a comparison of the Church being the body and Christ being the head. This is an interesting analogy. This was a somewhat common analogy in the Roman Empire. Seneca – a famed poet wrote that the Empire was the Body, and that Nero (Caesar) was the head. He is borrowing from common lit to explain a greater truth.
