1 Corinthians 12:13-17

For by one Spirit we were all baptized into one body, whether Jews or Greeks, whether slaves or free, and we were all made to drink of one Spirit.

For the body is not one part, but many.

If the foot says, “Because I am not a hand, I am not a part of the body,” it is not for this reason any less a part of the body.

And if the ear says, “Because I am not an eye, I am not a part of the body,” it is not for this reason any less a part of the body.

If the whole body were an eye, where would the hearing be? If the whole body were hearing, where would the sense of smell be?
