1 Corinthians 12:12-20

As a body is one though it has many parts, and all the parts of the body, though many, are one body, so also Christ. For in one Spirit we were all baptized into one body, whether Jews or Greeks, slaves or free persons, and we were all given to drink of one Spirit. Now the body is not a single part, but many. If a foot should say, “Because I am not a hand I do not belong to the body,” it does not for this reason belong any less to the body. Or if an ear should say, “Because I am not an eye I do not belong to the body,” it does not for this reason belong any less to 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? But as it is, God placed the parts, each one of them, in the body as he intended. If they were all one part, where would the body be? But as it is, there are many parts, yet one body.
