Nevertheless, I think that the Reformed Puritan's view that God "condemns and punishes actual sin, not our original sin state," while it may be correct (it is not our state of depravity that is the basis for guilt, but the actual sin of Adam our Federal head), is potentially misleading, because of the implicit follow-on that God therefore does not punish children, because they do not have "actual sin." But (as can be seen from the comments below) I had initially missed the Reformed Puritan's point, and perhaps I am now 0-2.
The Reformed Puritan's quotation from Calvin was (UPDATE: The Reformed Puritan has removed this quotation, because it could not be independently verified.):
“I everywhere teach that no one can be justly condemned and perish except on account of actual sin; and to say that the countless mortals taken from life while yet infants are precipitated from their mothers’ arms into eternal death is a blasphemy to be universally detested.” ~ John Calvin, Institutes, Book 4, p.335I could not confirm that this quotation was an accurate quotation, possibly because I have a different publication of the Institutes.
However, I note that Calvin, in "Calvin on Secret Providence," wrote:
As to your objection, that no one is justly condemned, unless on account of crime, and after crime, I have no quarrel with you on the former point, since I everywhere teach that no one perishes, except by the just judgment of God. At the same time I may not dissemble that a secret venom lurks in your language; for if the similitude you propose is admitted, God will be unjust for involving the whole family of Abraham, in the guilt of original sin. You deny that it is lawful for God to condemn any man, except on account of actual sin. Innumerable infants are, to this day, hurried out of life. Discharge now your virulence against God, for precipitating into eternal death innocent babes torn from their mother's breasts. Whoever detests not this blasphemy, when it is openly detected, may curse me to his heart's content. For I have no right to demand exemption from the railings of those who spare not the Almighty himself.
~ pp. 102-103, Lille's translation (1840)
The passage above is so directly contrary to the presentation in the Reformed Puritan that I cannot help but think that Calvin has been misquoted, and/or mistranslated.
Furthermore, it is plainly the teaching of Scripture that all are subject to the guilt of Adam's first sin, and that consequently even children who do not have personal sin, nonetheless are justly subject both to physical death and to eternal condemnation, unless God (in his mercy) spares them.
God makes no promise to show mercy on all infants who die before committing voluntary sin. God would be fully just to condemn all such to hell. After all, God is fully just to permit their death. If God does not show entire mercy on such infants, even in their death, God shows a degree of mercy in that He does not permit them to compound their guilt through voluntary sin of their own.
The Reformed Puritan states: "I heartily affirm the doctrine of Original Sin. We are radically corrupt, totally depraved and completely helpless towards our salvation without the monergestic work of God regenerating our souls. " But the doctrine of Original Sin encompasses:
The sinfulness of that estate whereinto man fell consists in the guilt of Adam's first sin, the want of original righteousness, and the corruption of his whole nature, which is commonly called original sin. (WSC, I forget which question number, emphasis added, wording may be slightly off)
Consequently, I'm not sure that endorsing only the corruption of His nature is completely endorsing the Reformed (and Scriptural) doctrine on the subject. But perhaps the Reformed Puritan was not trying to be exhaustive, and mentioned part for the whole, metonymously.
May we all praise our Merciful and Longsuffering God!
UPDATE: The Reformed Puritan, place of the original quotation above, which has now been removed, has quoted this:
His (Servetus’) third point is, That all who believe not in the Son remain in death, the wrath of God abideth on them (John 3:36); and, therefore, infants who are unable to believe lie under condemnation. I (Calvin) answer, that Christ does not there speak of the general guilt in which all the posterity of Adam are involved, but only threatens the despisers of the gospel, who proudly and contumaciously spurn the grace which is offered to them. But this has nothing to do with infants. At the same time, I meet him with the opposite argument. Every one whom Christ blesses is exempted from the curse of Adam, and the wrath of God. Therefore, seeing it is certain that infants are blessed by him, it follows that they are freed from death.
~ Calvin, Institutes, Bk 4
While I appreciate that the new quotation appears to be fully accurate, I don't think it establishes the point that the Reformed Puritan is trying to make. I don't think it says that infants are punished only for personal and not imputed sin.
