For, as in one body we have many members, but all the members have not the same office;
This verse draws its picture from something everyone knows: one body with many parts, each doing its own work. It sits inside an appeal about how a Christian should measure himself. Two questions follow. What does it mean that the members do not all have the same "office" (ESV: "function")? And which body does Paul mean?
The verse begins with "For" — it is the reason for something already said. What precedes is a warning against thinking too highly of oneself, and one writer points out how telling it is that such a warning was needed at all.
The Christian is not yet free from the sin that still lives in him, though chapter 6 teaches him how to deal with it, since he himself is in Christ. He needs the warning given here, "not to think of himself more highly than he ought to think, but to think with sober judgment, each according to the measure of faith that God has assigned." What creatures God's saints must be, if they need such a warning — a warning that even comes with a reason showing how fitting it is!
One writer traces the phrase back to our own arms, fingers and feet, then asks who the one body takes in.
"All members have not the same office." There is a great lesson in that. Each has its own function. The many members in one body are our arms, fingers and feet, and that is the picture Paul uses. This is the first teaching in the New Testament about the Body of Christ. "So we, though many, are one body in Christ." Who are the "we"? All Christians. You must not think of it as a society, a club, or a mere organisation, as men would say. Think of the members of the human body, and then ask who makes up the one body. "Many" — in fact all Christians on earth today are of it. "And individually members one of another" — I think that means, I cannot get on without you, and you cannot get on without me.
If gifts differ, no one person can carry them all.
What counted was God's dealing with each person, not a human commission given to one man or a few. So faith came in, and each is urged to think soberly of himself, and to use what God has given him instead of pretending to more. We do not see one member taking all the gifts to himself, or holding others back. We see many members, and yet only one body, with differing gifts, and each one urged to use them.
Why did the Spirit choose a body, and not some other image?
Romans 12:4 gives the illustration; Romans 12:5 applies that illustration. Forgive me for saying it, but if the Spirit had meant a regiment or a corporation, the picture He actually gave might seem unfortunate and misleading. We have many members in one body, but these are all organically united. The many organs and members are wonderfully suited to their different uses, yet in their very nature they are one, and together they form one living whole. They are not separate units, each with a life of its own, even if such units were all placed under one commander or director.
So who counts as a member — a person, or a group?
The Epistle to the Romans views the believer in his individual character rather than his corporate one. So it uses the same picture, not to explain the nature of the Church as doctrine, but to press the duty of every Christian to act according to the gift given to him… In these passages, note carefully: the members are individual believers. They are not different local assemblies, and still less are they voluntary associations, self-styled "Churches," divided from each other on points of doctrine, discipline, and order.
One detail marks the angle here: Romans says nothing about the Head.
In Romans 12 we have the same general idea as in 1 Corinthians. It assumes all of them are true saints. It looks at the members, not in union with the Head, but in their relationship to one another and in their service as individuals. "So we, though many, are one body in Christ, and individually members one of another."
- Cause — The verse gives a reason, not just a picture. It explains why no Christian should rate himself too highly.
- Gift — Different offices mean different gifts. Use what God has given you, and never pretend to more.
- Union — The tie is a living one, like a body. It is not a federation or an organisation under a director.
- Members — The members are individual believers, never denominations or societies. You belong to the one body, not to a group.
- Reach — Romans reaches this far and stops. It looks at the members in relation to one another, not at their union with the Head.
thus we, [being] many, are one body in Christ, and each one members one of the other.
Paul has just warned every believer not to think too highly of himself. Here he gives the reason: many as we are, we form one body, and each of us belongs to all the others. So who is the "we"? What makes this oneness real? And what does it change in everyday service?
Romans deals mostly with the individual before God. That makes this mention of the body both rare and pointed:
Here the apostle looks at the Christian life in a narrower circle... It is the only place in this letter that mentions the body, the Church, and it does so in relation to the duties of the members as individuals. The main subject is man in his own responsibility before God. But since there is one body, the members should serve in the common interest. We cannot act on our own, as if we had no tie with anyone on earth.
Verse 4 draws the picture of the human body. Verse 5 applies it to us, and it rules out any thought of the church as a crowd of separate people:
Romans 12:5 is the application of the figure. Christians differ widely, and each has his own exercises and activities. Yet in Christ they are one living body. That is, we are not thinking of a mere gathering of separate people, but of organs and members in a body... So this verse adds that we are all "members of one another." Each one is incomplete without all the rest. You could never say that of any group of people, however united they are.
Paul never narrows the word "we." Every Christian is inside it, and the last phrase spells out a plain mutual need:
"So we, though many, are one body in Christ." Who are the "we"? All Christians. You must not think of it as a society, a club, or an organisation, as people would say. Think of the members of the human body, then ask who makes up the one body. "Many" — in fact all Christians on earth today belong to it... "Individually members one of another" — I think that means I cannot get on without you, and you cannot get on without me.
Another writer rules out a common mistake about who these members are:
Notice in these passages that the members are individual believers. They are not different local assemblies, and still less different voluntary societies that call themselves "Churches" and are split from each other over doctrine, discipline, and order.
The words "in Christ" mark this unity off from anything God had before. Israel had one nation and one law. This body could not exist until Christ had died and risen:
In the past age there was one nation according to natural birth, and a covenant of commandments suited to that age. Now, by contrast, "we, though many, are one body in Christ, and individually members one of another." What a contrast this is to Israel... In the past no one could be in Christ. Christ had to die and be raised from the dead, or He would remain alone. But now we are one body in Christ... Here we have not so much the doctrine of the one body as the practice of all the members of that one body.
No member holds every function. So the verse rules out one person doing everything, and it traces each gift back to God rather than to a human appointment:
What God had dealt to each one was in view, not a human commission given to one man or to a few. So faith came in, and each one is urged to think soberly of himself, and to use what God has given him instead of pretending to more. We do not see one member soaking up all the gifts, or holding others back. We see many members and yet one body, with different gifts, urged to use them — not only out of love, because each of us is a member of all the others, but because of the grace God has given.
The phrase "members one of another" is one strand of a larger truth. Two other strands run beside it:
There are three ways of looking at membership in the Body. Linked with Christ: "we are members of His body" (Ephesians 5:30). Linked with all believers: "individually members one of another" (Romans 12:5). As individuals: "we are members in particular" (1 Corinthians 12:27). So we have three lines of truth here: connection with Christ, connection with one another, and individual responsibility.
- One — all Christians are one living body, not a club and not a group of clubs. The members are people, not churches.
- In Christ — this oneness could not exist until Christ died and rose. No one votes himself into it.
- Of one another — each member is incomplete without the rest. No one carries every function.
- Sober — see yourself as one member, and high thoughts die. You use what God gave you and stop pretending to more.
- Serving — Romans gives the fact, not the full teaching, so that no one serves alone. Each works in the common interest.
