12 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. 13 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. 14 For in fact the body is not one member but many. 15 If the foot should say, “Because I am not a hand, I am not of the body,” is it therefore not of the body? 16 And if the ear should say, “Because I am not an eye, I am not of the body,” is it therefore not of the body? 17 If the whole body were an eye, where would be the hearing? If the whole were hearing, where would be the smelling? 18 But now God has set the members, each one of them, in the body just as He pleased. 19 And if they were all one member, where would the body be? 20 But now indeed there are many members, yet one body. 21 And the eye cannot say to the hand, “I have no need of you”; nor again the head to the feet, “I have no need of you.” 22 No, much rather, those members of the body which seem to be weaker are necessary. 23 And those members of the body which we think to be less honorable, on these we bestow greater honor; and our unpresentable parts have greater modesty, 24 but our presentable parts have no need. But God composed the body, having given greater honor to that part which lacks it, 25 that there should be no schism in the body, but that the members should have the same care for one another. 26 And if one member suffers, all the members suffer with it; or if one member is honored, all the members rejoice with it. 27 Now you are the body of Christ, and members individually.

Since The Church Is A Body, We Can Clearly See These Seven Principles:

1. 1. The body is coordinated because each member obeys Christ, the only Head.

2. 2. No one should feel less because he/she does not do exactly what another does. God never approved a system of clergy and laity, where everyone depends upon a professional. All of us work doing what we can and improving our abilities through study and practice, and all of us depend upon what others do. Each one is reliable and yet dependent.
   3. No one should feel superior to another because of what he/she can do.

4. 4. We all need each other—we do not have any “throw-away” members.

5. 5. Each one should look for and do what he/she can do in obedience to Christ.

6. 6. It is not acceptable that a few work and the others do nothing and depend upon the work of others.

7. 7. The proper result is achieved when all, though their obedience to the word of God, work with the same purpose, Christ’s purpose—to seek the lost.
