According to Erasmus, the option of conversionconversion to Christianity was open to all, including the Jews, and he was eager for this to happen. However, those Jews who converted to Christianity were defined by Erasmus as “half-Jews, half-Christians,” and he believed that their Jewish essence/nature did not change. Converts from Judaism to Christianity were also rated by Erasmus as lower than other Christians. Researchers who study conversions of Jews to Christianity have concluded that in general Jews who converted to Christianity were considered inferior because of their background or immutable, inherent qualities. Their essence remained unchanged, and they were not considered Christians but baptized Jews. In principle, as far as “once a Jew, always a Jew” was concerned, Erasmus did not differ from Martin Luther. The lenient narrative ignores all this.
