What if someone else sins for you is put on hold (rightly so) for being a truth question of the form "Is X a sin?".
I think this question is interesting and could be salvaged if it is reformulated as "Are there examples from the Bible where behavior X is punished?" which seems to avoid the Truth issue and is just a question for an example from the text. That seems answerable. If there are no examples it still does not mean X is a sin, nor does a punishment necessarily mean X is a sin today. But for some issues it points in a certain direction.
So... can and should this question, or others like it, be salvaged in this way? Or is too close to the unwanted "Is X a sin?"?
