The stick is a fragment of the cross of christ.

And Christ was a brown-haired Zauberbiest who used the stick along with his powers to create miracles and manipulate people to thinking he was the son of an omnipotent figure he made up. Zauberbiests are natural born power-hungry leaders, after all. In the end, he was burnt to the cross for his "sins", only to be resurrected by the stick seconds later. IT MAKES PERFECT SENSE!!

That should do wonders for the show's ratings in the bible belt markets...
