Steve says that he has been patient up until now, but no-one has presented to, granted by law or writ, submitted control over, or otherwise relinquished to him the cheese. He feels the need to smash someone or something soon, but before he does that, he wants everyone to know that the papyrus given to him by the man who had fallen off his horse is proof enough. This papyrus is the word of god. It's written down for Christ's sake. It says right there in plain ancient Greek that all cheese belongs to the cat Steve who must have control over all of it immediately. The words written down on that papyrus are absolute and incontrovertible. Listen only to Steve's papyrus and to Steve's papyrus alone and you'll find truth and justice, and...the good life,...or happiness or some shit. But you must hand over the cheese now lest you suffer eternal damnation or oblivion,...or some such other crap like that.
