This claim is substantiated by the fact that in the Netherlands, the words Hocus pocus are usually accompanied by the additional words pilatus pas, and this is said to be based on a post-Reformation parody of the traditional Catholic ritual of transubstantiation during mass, being a Dutch corruption of the Latin words "Hoc est corpus", meaning this is (my) body, and the credo "sub Pontio Pilato passus et sepultus est", meaning under Pontius Pilate he suffered and was buried.
