Samuel Aron from Oppeln (a.k.a Johanne Polycarpo Besser). Die Mittel Wie auch die Hindernisse Bey der heutigen Juden-Bekehrung

The author, a converted Jew from a Rabbinic family in Poland, recounts his difficulties in seeking to covert Jews to Christianity and suggests more effective ways of success. He complains: "Wenn die Maus die Katze frisst, wird der Jud ein rechter Christ!" [“When the mouse eats the cat, then will the Jew become a righteous Christian!"]
