Jesuit statutes requiring four generations of non-Jewish ancestry institutionalized antisemitism

Evidence

It was the Jesuits who had always best represented, both in the written and spoken word, the antisemitic school of the Catholic clergy. This is largely the consequence of their statutes according to which each novice must prove that he has no Jewish blood back to the fourth generation. And since the beginning of the nineteenth century the direction of the Church’s international policy had passed into their hands. — Hannah Arendt, The Origins of Totalitarianism, 300

Categorization

• XREF: Directly relevant to the reader’s Islamophobia toolkit — regulation of Jewish blood in Church institutions parallels racialization mechanisms later analyzed in the field (racial purity standards as institutionalized exclusion).
• SEED: Angle: the concrete institutional mechanism (blood-purity statutes) that made a religious order a carrier of racial antisemitism — a case study in how exclusion gets codified in organizational rules.
• QUESTION: Worth verifying: the stated Jesuit novice statute about Jewish blood going back four generations — a dated practice worth checking the details of.
