15 If the foot would 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 would 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 the hearing be? If the whole body were hearing, where would the sense of smell be? 18 But as it is, God arranged the members in the body, each one of them, as he chose. 19 If all were a single member, where would the body be? 20 As it is, there are many members, 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 members of the body that seem to be weaker are indispensable, 23 and those members of the body that we think less honorable we clothe with greater honor, and our less respectable members are treated with greater respect; 24 whereas our more respectable members do not need this. But God has so arranged the body, giving the greater honor to the inferior member, 25 that there may be no dissension within the body, but the members may have the same care for one another. 26 If one member suffers, all suffer together with it; if one member is honored, all rejoice together with it.

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.
