RT Article T1 The Heresy of the Ancestors: A Case Study in Religion and Identity from Early Modern Catholicism JF Journal of religion & society. Supplement VO 13 SP 142 OP 155 A1 Fleming, Julia A. LA English PB Rabbi Myer and Dorothy Kripke Center for the Study of Religion and Society at Creighton University YR 2016 UL https://www.ixtheo.de/Record/1799389936 AB This case study examines the background to Johann Lerchenfeld's successful petition for nullification of his religious vows as a Theatine on the grounds of his religious ancestry. While Lerchenfeld's forebears were Protestant, the exclusionary provisions that served as the basis for his release were the product of concerns over "New Christian" lineage in Iberia, and the intersection of medieval disabilities for the children of heretics with anxieties regarding so-called purity of blood. The Theatine exclusionary rules, and their amendment in 1710, reflect the changing face of religious identity in Early Modern Europe
