1 Corinthians 12:12-18 NRSV
For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ. For in the one Spirit we were all baptized into one body—Jews or Greeks, slaves or free—and we were all made to drink of one Spirit.
Indeed, the body does not consist of one member but of many. If the foot would say, “Because I am not a hand, I do not belong to the body,” that would not make it any less a part of the body. And if the ear would say, “Because I am not an eye, I do not belong to the body,” that would not make it 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? But as it is, God arranged the members in the body, each one of them, as he chose.
