1 Corinthians 12:12-21

For as the body is one, and hath many members, and all the members of the body, being many, are one body; so also is Christ. For in one Spirit were we all baptized into one body, whether Jews or Greeks, whether bond or free; and were all made to drink of 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; it is not therefore not of the body. And if the ear shall say, Because I am not the eye, I am not of the body; it is not therefore not of the body. If the whole body were an eye, where were the hearing? If the whole were hearing, where were the smelling? But now hath God set the members each one of them in the body, even as it pleased him. And if they were all one member, where were the body? But now they are many members, but one body. And the eye cannot say to the hand, I have no need of thee: or again the head to the feet, I have no need of you.
