Perhaps this quote will help understand the two main differences in thinking about the reconciliation between God and man in Christ:
Is this God's plan, to become a human being and die, so that God won't have to destroy us instead? Is it God's prescription to have Jesus suffer for sins he did not commit so God can forgive the sins we do commit? That's the wrong side of the razor. Jesus was already preaching the forgiveness of sins and forgiving sins before he died. He did not have to wait until after the resurrection to do that. Blood is not acceptable to God as a means of uniting human community or a price for God's favor. Christ sheds his own blood to end that way of trying to mend our divisions. Jesus' death isn't necessary because God has to have innocent blood to solve the guilt equation. Redemptive violence is our equation. Jesus didn't volunteer to get into God's justice machine. God volunteered to get into ours. God used our own sin to save us.
(Mark S. Heim. Saved from Sacrifice: A Theology of the Cross)
