He said HUMANLY SPEAKING!!!!!!!!!!!
I think that since his statement, no matter how you read it, is blasphemy, I would argue that he was Demonically Speaking.
Christ work was finished at the cross. His penultimate statement at the cross was "It is Finished." The work was done. It was a victory and not a failure.
You can make all the excuses you want for this miserable failure of a Pope, but you can't polish a turd and call it art.
