Counter-Arguments

The strongest case that this verse does not belong in this theme.

One People of God

This verse uses a bodily metaphor to discuss the integration and function of different parts within a single entity, but it does not explicitly mention or allude to "believing Jews and Gentiles" or any concept of a unified "people of God."
