I Corinthians 12:12-15

For as the body is one and has many members, but all the members of that one body, being 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 have all been made to drink into one Spirit. For in fact the body is not one member but many. If the foot should say, “Because I am not a hand, I am not of the body,” is it therefore not of the body?
