The Jesuit order excluded Jewish converts and their descendants for centuries via blood laws

Evidence

Originally, according to the Convention of 1593, all Christians of Jewish descent were excluded. A decree of 1608 stipulated reinvestigations back to the fifth generation; the last provision of 1923 reduced this to four generations. These requirements can be waived by the chief of the order in individual cases. — Hannah Arendt, The Origins of Totalitarianism, 2131

Categorization

• XREF: Purity-of-blood statutes in the Jesuit order prefigure modern racial/national genealogy tests — a mechanism the reader’s scaffolding theory toolkit needs for race-thinking and genealogical exclusion. — connects to: Iberian blood-purity laws served a political project of class elevation and exclusion
• QUESTION: The waiving clause by the order’s chief hints at how such blood tests were discretionary, not absolute — worth tracing how Arendt uses this.
