1 Corinthians 12:11-15

But one and the same Spirit works all these things, distributing to each one individually just as He wills.

For just as the body is one and yet has many parts, and all the parts of the body, though they are many, are one body, so also is Christ.

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.
