Paul’s analogy of the body has its limits
We do have other images we might imagine for “an organic communion.” We might, for example, think about the vine and the branches. It speaks to us of growth that is rooted in Christ, but that can lead in a variety of directions. It speaks to us of fruitfulness, and can connect in our reflections to the blood of Christ, which we receive in the Eucharist and in which we are cleansed from sin.
