15 If the foot should say, "Because I am not a hand, I do not belong to the body," that would not make it any less a part of the body. 16 And if the ear should say, "Because I am not an eye, I do not belong to the body," that would not make it any less a part of the body. 17 If the whole body were an eye, where would be the hearing? If the whole body were an ear, where would be the sense of smell? 18 But as it is, God arranged the organs in the body, each one of them, as he chose. 19 If all were a single organ, where would the body be? 20 As it is, there are many parts, yet one body. 21 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 On the contrary, the parts of the body which seem to be weaker are indispensable, 23 and those parts of the body which we think less honorable we invest with the greater honor, and our unpresentable parts are treated with greater modesty, 24 which our more presentable parts do not require. But God has so composed the body, giving the greater honor to the inferior part, 25 that there may be no discord in the body, but that the members may have the same care for one another. 26 If one member suffers, all suffer together; if one member is honored, all rejoice together.

Commentary on 1 Corinthians 12:12-26
(Read 1 Corinthians 12:12-26)
Christ and his church form one body, as Head and members. Christians become members of this body by baptism. The outward rite is of Divine institution; it is a sign of the new birth, and is called therefore the washing of regeneration, Titus 3:5. But it is by the Spirit, only by the renewing of the Holy Ghost, that we are made members of Christ's body. And by communion with Christ at the Lord's supper, we are strengthened, not by drinking the wine, but by drinking into one Spirit. Each member has its form, place, and use. The meanest makes a part of the body. There must be a distinction of members in the body. So Christ's members have different powers and different places. We should do the duties of our own place, and not murmur, or quarrel with others. All the members of the body are useful and necessary to each other. Nor is there a member of the body of Christ, but may and ought to be useful to fellow-members. As in the natural body of man, the members should be closely united by the strongest bonds of love; the good of the whole should be the object of all. All Christians are dependent one upon another; each is to expect and receive help from the rest. Let us then have more of the spirit of union in our religion.
