Paul is alerting the Corinthians to Satan’s divide-and-conquer strategy and urges them to resist with the truth that they are inescapably one body with many parts. Because we are made in the image of a triune God and can do nothing other than bear his image of oneness, we exist in loving equal relationship with one another. This is not something we attain, but a oneness based in the Holy Spirit. Our standard of wellbeing in the body of Christ is the whole body well-being, not just any one part.
