It is a mistake to not carry Romans 5 into Romans 6. If we carry the thought of the representative character of the two Adams from the one chapter into the other, then the difficulty vanishes.

All men sinned in the first man’s act of sin; for that public act was representative, and all Adam’s offspring were included in it. From God’s perspective, there have been but two men in the world, with the two families of which they are the heads; there have been just two public representatives.

The idea of Christ being our Surety and the representation of His atonement as the act of “one for many”, run through this entire section of Romans. But the passage we are studying (Romans 6:1-8) contains one difference as compared with other passages, and that is that here we are described as doing what our representative did.

Let us notice the expressions used in Romans 6:1-8: It is said that “we died to sin (verse 2). As this phrase is misunderstood quite frequently, we must discover what it really means. It frequently occurs in the writings of Paul in different forms, and it always alludes, not to an inward deliverance from sin, but to the Christian’s objective relation. It means that we are legally dead to sin in Jesus Christ.

This is made very clear by two other expressions occurring in the section. The first of these passages applies the same language to the Lord Himself; for He is said to have died to sin once (verse 10). Now the only sense in which the Sinless One can be regarded as dying to sin, is that of dying to its guilt, or to the condemning power which goes along with sin, and which must run its course wherever sin has been committed. He died to the guilt or criminality of sin when it was laid on Him. He certainly did not die to sins indwelling power.

The second of these phrases shows that this dying was the meritorious cause of our justification. “He that is dead has been justified from sin” (verse 7). The justification of the Christian is thus based on his co-dying with Christ; that is, we are said to have died when Christ died, and to have done what Christ did. The words undoubtedly mean a co-dying with Christ in that one corporate representative deed; that is, they mean that we were one with Christ in His obedience unto death, just like we were one with Adam in his disobedience.

Christ’s death to sin belongs to us, and is as much ours as if we had born the penalty ourselves. And the justification by which we are forgiven and accepted has no other foundation. It is noteworthy that Romans 5 describes all this in the third person, whereas Romans 6 describes it in the first person, and from our own share in it.

Paul also says in this section that our old man is crucified, or co-crucified with Him. The entire section of which this is a part is to be regarded not as an exhortation, but as the simple statement of fact; this passage does not set forth anything done by us, but something done on our account, or for our sake, by a Surety, in whose performance we participate.

It might be asked, “can’t we understand that these statements designate two separate actions, one done by Christ, and a similar or parallel one by us?” NO. The acts are not two, but one, described from two different points of view. There is not one crucifixion on the part of Christ, and a second, parallel and similar but different, crucifixion on the part of His people. There is but one corporate act—the act of “one for many.”

But what is the old man that is said to be co-crucified with the Lord? Does not this refer to our inward corruption? NO it does not. Such an explanation is untenable, as it would make the expression synonymous with the next clause which is not only bad theology but also inept reasoning. Instead, the first clause is made the condition of the second.

The old man is crucified in order that the body of sin (sin within us, or the flesh) be destroyed. Now there must be a difference between the two clauses, as the former is in order to attain the latter. The old man said to be crucified with Christ, is therefore our standing “in Adam”, which is terminated so that we have a new relationship to God in the crucified Surety.

To summarize, Romans 6:1-5 says we have been crucified with Christ, which tells us that our standing has changed from being “in Adam” (with its curse and condemnation) to being “in Christ” (with all of its blessings and benefits).

The first five verses of Romans 6 are statements of fact, then verse 6 is an exhortation, so a one-sentence summary is, “because we were crucified with Christ, we should no longer be slaves of sin.”

But to bring even more clarity to the mind of his readers, Paul says we were baptized into His death (verse 3). Christ is presented to us as laden with sin , and satisfying divine justice; and baptism, as a symbolical representation, shows our connection with Him, or rather our participation in that great corporate act which Jesus did on the cross, in the place of all His peopleone what He underwent, to satisfy divine justice. The symbol of baptism teaches this, and Paul tells us the fact that it was a baptism into His death, an emblem of oneness with Christ, or fellowship with Him in His death to sin (verse 10).
