"Jesus was not innocent at death. That is the point."

?? When did he sin?
Representational guilt is the essence of the gospel claim. Federal representation is at the core of Christianity. Thus the claim that "he who knew no sin BECAME sin on our behalf, so that we might be made the righteousness of God." Sorry to throw out bible verses. This was just one that went to the heart of the matter.
Good question.
"He who knew not sin, became sin for our sake."
Sheesh! (And no I can't quote chapter and verse--the Holy Apostle Paul wrote words to that effect, find a sola scriptura protestant if you want a footnote.)
