I'm just talking here. Not trying to make a theological argument so take it for what it's worth. But I do believe that our revealed knowledge of God shows us that it is in his nature to tend to want to punish sin. It's also in his nature to want to show mercy. And it's also true that he he perfectly righteous and just and wants us all collectively to know that. So you have all these thoughts about which are difficult for us to deal with as humans. And I'll tell you something. The Reformers were the ones who first started looking at this in detail apparently, in relation to our sin, and the work of Christ and I think they should be applauded for it.
Not all of the Reformers. John Calvin.
Each Reformer had specific concerns. Luther, for example, carried over the idea of Satisfaction Theory (he just didn't identify an error there, which makes sense...but he didn't offer an objection Calvin, or other Atonement theories, either).
We have to recognize that our focus often depends on our environment. Calvin was trained in philosophy and humanistic law, so it is natural that is where he would go. Luther first became concerned over indulgences (a matter of justification) so it is logical that's where he would go.
My concern here is that we do not place a demand, or desire, upon God to punish sinful actions separate from the source of those actions.
For example, put yourself in place of judge. Suppose I punch you and you want to forgive me. Is there a need for you to punish my crime against you by punching somebody else in order to forgive me?
Punishing a crime except by punishing the guilty party is unjust. The crime itself is never punished. The criminal is punished for committing the crime.
I'm just trying to think out your post. I do not understand why you believe God has a need to punish actions separated from the guilty person.
