As a Jew myself, I had heard (not knowing for sure if it’s factual) that Jews who ate Kosher food did not get the Bubonic plague. Presumably, this was due to the fact that pork carried the virus of this particular plague. It also might have accounted for the fact that non-Jews were suspicious of why the Jews were not as affected.
Thomas Aquinas was an Italian scholar of philosophy and theology. He tried to bring together ancient philosophical ideas about reason and medieval theological beliefs about faith. Hope it help!
