1 Corinthians 12:12-16

For as the body is one, and hath many members, and all the members of that one body, being many, are one body: so also is Christ.

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.

For the body is not one member, but many.

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

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?
