15 If the foot would say, “Because I’m not the hand, I’m not part of the body,” it is not therefore not part of the body. 16 If the ear would say, “Because I’m not the eye, I’m not part of the body,” it’s not therefore not part of the body. 17 If the whole body were an eye, where would the hearing be? If the whole were hearing, where would the smelling be? 18 But now God has set the members, each one of them, in the body, just as he desired. 19 If they were all one member, where would the body be? 20 But now they are many members, but one body. 21 The eye can’t tell the hand, “I have no need for you,” or again the head to the feet, “I have no need for you.” 22 No, much rather, those members of the body which seem to be weaker are necessary. 23 Those parts of the body which we think to be less honorable, on those we bestow more abundant honor; and our unpresentable parts have more abundant propriety; 24 whereas our presentable parts have no such need. But God composed the body together, giving more abundant honor to the inferior part, 25 that there should be no division in the body, but that the members should have the same care for one another. 26 When one member suffers, all the members suffer with it. Or when one member is honored, all the members rejoice 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.
