The apostle here makes out the truth of what was above asserted, and puts the gifted men among the Corinthians in mind of their duty, by comparing the church of Christ to a human body.
I. By telling us that one body may have many members, and that the many members of the same body make but one body (1 Cor. 12:12): As the body is one, and hath many members, and all members of that one body, being many, are one body, so also is Christ; that is, Christ mystical, as divines commonly speak. Christ and his church making one body, as head and members, this body is made up of many parts or members, yet but one body; for all the members are baptized into the same body, and made to drink of the same Spirit, 12:13. Jews and Gentiles, bond and free, are upon a level in this: all are baptized into the same body, and made partakers of the same Spirit. Christians become members of this body by baptism: they are baptized into one body. The outward rite is of divine institution, significant of the new birth, called therefore the washing of regeneration, Titus 3:5. But it is by the Spirit, by the renewing of the Holy Ghost, that we are made members of Christ?s body. It is the Spirit?s operation, signified by the outward administration, that makes us members. And by communion at the other ordinance we are sustained; but then it is not merely by drinking the wine, but by drinking into one Spirit. The outward administration is a means appointed of God for our participation in this great benefit; but it is baptism by the Spirit, it is internal renovation and drinking into one Spirit, partaking of his sanctifying influence from time to time, that makes us true members of Christ?s body, and maintains our union with him. Being animated by one Spirit makes Christians one body. Note, All who have the spirit of Christ, without difference, are the members of Christ, whether Jew or Gentile, bond or free; and none but such. And all the members of Christ make up one body; the members many, but the body one. They are one body, because they have one principle of life; all are quickened and animated by the same Spirit.
II. Each member has its particular form, place, and use. 1. The meanest member makes a part of the body. The foot and ear are less useful, perhaps, than the hand and eye; but because one is not a hand, and the other an eye, shall they say, therefore, that they do not belong to the body? 12:15, 16. So every member of the body mystical cannot have the same place and office; but what then? Shall it hereupon disown relation to the body? Because it is not fixed in the same station, or favoured with the same gifts as others, shall it say, ?I do not belong to Christ?? No, the meanest member of his body is as much a member as the noblest, and as truly regarded by him. All his members are dear to him. 2. There must be a distinction of members in the body: Were the whole body eye, where were the hearing? Were the whole ear, where were the smelling? 12:17. If all were one member, where were the body? 12:19. They are many members, and for that reason must have distinction among them, and yet are but one body, 12:20. One member of a body is not a body; this is made up of many; and among these many there must be a distinction, difference of situation, shape, use, etc. So it is in the body of Christ; its members must have different uses, and therefore have different powers, and be in different places, some having one gift, and others a different one. Variety in the members of the body contributes to the beauty of it. What a monster would a body be if it were all ear, or eye, or arm! So it is for the beauty and good appearance of the church that there should be diversity of gifts and offices in it. 3. The disposal of members in a natural body, and their situation, are as God pleases: But now hath God set the members, every one of them, in the body, as it hath pleased him, 12:18. We may plainly perceive the divine wisdom in the distribution of the members; but it was made according to the counsel of his will; he distinguished and distributed them as he pleased. So is it also in the members of Christ?s body: they are chosen out to such stations, and endued with such gifts, as God pleases. He who is sovereign Lord of all disposes his favours and gifts as he will. And who should gainsay his pleasure? What foundation is here for repining in ourselves, or envying others? We should be doing the duties of our own place, and not murmuring in ourselves, nor quarrelling with others, that we are not in theirs. 4. All the members of the body are, in some respect, useful and necessary to each other: The eye cannot say to the hand, I have no need of thee; nor the head to the feet, I have no need of your: nay, those members of the body which seem to be more feeble (the bowels, etc.) are necessary (12:21, 22); God has so fitted and tempered them together that they are all necessary to one another, and to the whole body; there is no part redundant and unnecessary. Every member serves some good purpose or other: it is useful to its fellow-members, and necessary to the good state of the whole body. Nor is there a member of the body of Christ but may and ought to be useful to his fellow-members, and at some times, and in some cases, is needful to them. None should despise and envy another, seeing God has made the distinction between them as he pleased, yet so as to keep them all in some degree of mutual dependence, and make them valuable to each other, and concerned for each other, because of their mutual usefulness. Those who excel in any gift cannot say that they have no need of those who in that gift are their inferiors, while perhaps, in other gifts, they exceed them. Nay, the lowest members of all have their use, and the highest cannot do well without them. The eye has need of the hand, and the head of the feet. 5. Such is the man?s concern for his whole body that on the less honourable members more abundant honour is bestowed, and our uncomely parts have more abundant comeliness. Those parts which are not fit, like the rest, to be exposed to view, which are either deformed or shameful, we most carefully clothe and cover; whereas the comely parts have no such need. The wisdom of Providence has so contrived and tempered things that the most abundant regard and honour should be paid to that which most wanted it, 12:24. So should the members of Christ?s body behave towards their fellow-members: instead of despising them, or reproaching them, for their infirmities, they should endeavour to cover and conceal them, and put the best face upon them that they can. 6. Divine wisdom has contrived and ordered things in this manner that the members of the body should not be schismatics, divided from each other and acting upon separate interests, but well affected to each other, tenderly concerned for each other, having a fellow-feeling of each other?s griefs and a communion in each other?s pleasures and joys, 12:25, 26. God has tempered the members of the body natural in the manner mentioned, that there might be no schism in the body (12:25), no rupture nor disunion among the members, nor so much as the least mutual disregard. This should be avoided also in the spiritual body of Christ. There should be no schism in this body, but the members should be closely united by the strongest bonds of love. All decays of this affection are the seeds of schism. Where Christians grow cold towards each other, they will be careless and unconcerned for each other. And this mutual disregard is a schism begun. The members of the natural body are made to have a care and concern for each other, to prevent a schism in it. So should it be in Christ?s body; the members should sympathize with each other. As in the natural body the pain of the one part afflicts the whole, the ease and pleasure of one part affects the whole, so should Christians reckon themselves honoured in the honours of their fellow-christians, and should suffer in their sufferings. Note, Christian sympathy is a great branch of Christian duty. We should be so far from slighting our brethren?s sufferings that we should suffer with them, so far from envying their honours that we should rejoice with them and reckon ourselves honoured in them.
