1 Corinthians 12:15

If the foot shall say, Because I am not the hand, I am not of the body; is it therefore not of the body?
13

For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.

14

For the body is not one member, but many.

15

If the foot shall say, Because I am not the hand, I am not of the body; is it therefore not of the body?

16

And if the ear shall say, Because I am not the eye, I am not of the body; is it therefore not of the body?

17

If the whole body were an eye, where were the hearing? If the whole were hearing, where were the smelling?

Counter-Arguments

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

One People of God

The verse uses an analogy of body parts to discuss internal unity and function within a single entity, not the inclusion or unification of distinct groups like "believing Jews and Gentiles." The text itself does not mention Jews, Gentiles, or any other specific people groups.
