The Jewish people met and picked an aged but wise Rabbi Moishe to represent them in the debate. However, as Moishe spoke no Italian and the Pope spoke no Yiddish, they all agreed that it would be a silent debate.
On the chosen day, the Pope and Rabbi Moishe sat opposite each other for a full minute before the Pope raised his hand and showed three fingers.
Rabbi Moishe looked back and raised one finger.
Next, the Pope waved his finger around his head. Rabbi Moishe pointed to the ground where he sat.
The Pope then brought out a communion wafer and a chalice of wine. Rabbi Moishe pulled out an apple.
With that, the Pope stood up and declared that he was beaten, that Rabbi Moishe was too clever, and that the Jews could stay.
Later, the Cardinals met with the Pope, asking what had happened. The Pope said, “First, I held up three fingers to represent the Trinity. He responded by holding up one finger to remind me that there is still only one God common to both our beliefs. Then, I waved my finger to show him that God was all around us. He responded by pointing to the ground to show that God was also right here with us. I pulled out the wine & wafer to show that God absolves us of all our sins. He pulled out an apple to remind me of original sin. He had me beaten & I couldn’t continue.”
Meanwhile the Jewish community gathered around Rabbi Moishe. “How did you win the debate?” they asked.
“I haven’t a clue,” said Moishe. “First he said to me that we had three days to get out of Italy, so I gave him the finger. Then he tells me that the whole country would be cleared of Jews and I said to him, we’re staying right here.”
“And then what?” asked a woman.
“Who knows?” said Moishe, “He took out his lunch, so I took out mine.”
