Huh? Do you mean, did NOT impute...sin to Christ?
I believe you are thinking that imputation is an actuality that the person/subject does. It is not. It is a regard or belief
by another influential person that that first person is sinful. In accounting, it would be to regard someone as 'good for' $100K, for ex., when you see that they don't have it but have reason to think they will or that some 3rd party is going to supply it. Imputation is thus
against the facts.
That's why there is the blessing of Ps 32 'the man to whom God does not impute his sin.' That means the guilt of it is treated
as if it had not taken place; in reality it did.
Christ was made to be sin (was regarded as having) and punished
as a sin offering, so that we could have the righteousness of God imputed to us. Christ never sinned, but was
reckoned to have. 2 Cor 5. Nor are we perfect as Christians; Luther called it an 'alien' righteousness. Not like a man who came to my church a couple years ago and stood up to rebuke the teacher saying 'I haven't sinned in 2 years!'
The sin offering analogy is of God 'laying his hands' on the person bearing them; from the Levitical law about scape-goats. Likewise John the Baptizer said 'the Lamb takes away the sin of the world.' It is not that evil/sin has stopped, surely!
I have examples of Western Christian literature which shows this usage, from Shakespeare to Austen to Cody. In real estate, during the purchase period, some documents read that the buyer is imputed to have the amount needed to close, before bank approval or other proof. Let me know if you would like to see them. At least one script used the same idea, where a marriage engagement
imputed a nationality to a foreign spouse that they would otherwise have been working illegally, before the person could gain citizenship, which would take months.
The Greek term is '
logizo' if you want to consider more. Another clarifying example is in Col 2, where the accusing Judaistic teachers 'dis-
logizo' the believers. That means they consider them 2nd rate because all they have is Christ; they don't have the Law practices and traditions that would make them 'real' believers. So 'discredited' is closer than deceived (logizo is often about credit, Rom 4:3 6, 9, 10, 11, 22, 23, 24), but the effect is deception.
