You are mistaking the absence of a single English word for the absence of the doctrine it names. That is the word–concept fallacy, assuming that if a particular word does not appear in a passage then the concept it names is absent from the passage. See D. A. Carson, Exegetical Fallacies, 2nd ed. (Baker Academic, 1996); Moisés Silva, Biblical Words and Their Meaning, rev. ed. (Zondervan, 1994); James Barr, The Semantics of Biblical Language (Oxford University Press, 1961).
I do not agree with your assessment of my response. When I said, "it doesn't say that," the implication is that it is not teaching the doctrine of imputation in that verse. So then, your assessment is a fallacy, since you are assuming that my response was merely because the term "impute" was not in the text. But that was not the case.
Paul's forensic argument in Romans 5:14-19 embodies the very logic of imputation, namely, liability transferred on the basis of federal representation. The concept is structurally and contextually present, even though the technical English gloss "impute" is absent. Paul is arguing representationally and forensically:
- v. 13 uses ἐλλογέω ("count/charge/credit"): "sin is not counted where there is no law." The lexical field of imputation is already in the pericope.
The way I read this verse is that 4:8 is the same context. Paul is quoting Ps. 32:2 "Blessed
is the man to whom the LORD does not impute iniquity." The premise in this context, how it reads, is that Paul is talking about people "of age" - that is, who already have knowledge of moral law, and have already sinned. This is the context of Ps. 32:2. So then, this imputation of sin is the holding of the sinner culpable for the sin he has committed, not holding everyone culpable for Adam's sin.
- vv. 16, 18 uses κατάκριμα ("condemnation"): a courtroom term, not a mere description of corruption.
- v. 19 uses κατεστάθησαν ("by the one man's disobedience the many were made [κατεστάθησαν, constituted] sinners"): parallel to being constituted righteous in Christ; if you deny forensic imputation in Adam, you shipwreck the parallel that grounds justification in Christ (whatever κατεστάθησαν means for Adam must apply analogically to κατασταθήσονται for Christ).
The way Adam's disobedience made many sinners is that Adam's sin caused his progeny to be born with a sin nature. "Many were made sinners" does not necessarily mean that his sin was imputed to everyone. And how do you know that justification in Christ is a "parallel" rather than a contrast? The imputation of sin on the sinner has to do with the sinner's own sin, not someone else's sin. In contrast, the imputation of righteousness has to do with someone else's righteousness.
- The verb is καθίστημι, which in Romans 5:19 is the aorist passive indicative, third person plural (κατεστάθησαν, constituted/appointed/made). Lexically, καθίστημι means to bring into a particular state or relation, to appoint, to make, to constitute (BDAG, s.v. καθίστημι). This range includes judicial or declarative senses. For example: Matthew 24:45, "whom his master has set over his household" (appointed to a role); Acts 7:10, Pharaoh "made him ruler" or governor (appointed, not transformed); Hebrews 5:1, "every high priest is appointed to act on behalf of men."
Romans 5:12-21 contrasts two representative heads, Adam and Christ. The governing ideas are judgment and condemnation versus justification and life, all forensic or covenantal categories. When Paul says the many were constituted sinners, he is not describing an ethical change in personal character but a judicial placement under condemnation through Adam's disobedience. The result—death reigned—follows from legal liability.
- Lexically: καθίστημι means to appoint, constitute, not become.
This one I have difficulty objecting to, which I think is the strongest argument so far in favor of the imputation idea.
- Syntactically: The Adam–Christ parallel demands forensic symmetry.
I don't think it demands that as I explained above, as I don't think it's symmetrical.
- Contextually: The whole pericope revolves around judicial categories—sin/righteousness, judgment/life, condemnation/justification.
Judicial category does not have to exclude 'becoming'. By the nature of sin, people become sinners, become condemned, and die (spiritually); and contrasting that, by the nature of the indwelling Holy Spirit, people become righteous, become justified, and live forever. How is this excluded from Paul's argument?
- Theologically: Denying the forensic sense in Adam undermines it in Christ.
I don't agree with this premise. Finding ourselves in a sinful condition (and not blaming it on Adam) does not undermine the substitutionary nature of Christ's righteousness and justification of the believer. I'm not assuming symmetry.
So then, if imputation of Adam's sin is true, and everyone is guilty forensically (including infants) as you claim:
1. What do you do with David indicating that his son dying in infancy went to heaven?
2. What do you do with Jesus' statement about little children, "for to such belongs the kingdom of heaven"?
3. Do you think that Paul's statement about children of unbelievers are "unclean" means that they go to hell if they die in infancy?
4. Is your interpretation of Rom. 7:9, where "I was once alive" is merely a point of view or a psychological construct, and not a literal "I was spiritually alive" because he really was innocent, not having committed any sin, or at least not having his own sin imputed to him because he was "without the law" at the time?
