Note 506 — Chapter IV · ESTABLISHMENT OF THE INQUISITION.
Reading edition
See the oath taken, July 20, 1487, by the officials of Catalonia and Barcelona to the inquisitor Alonso de Spina in Carbonell’s De Gestis Hæreticorum (Coleccion de Documentos de la Corona de Aragon, XXVIII, 6).
The decretals in question were issued by Lucius III, Innocent III, Clement IV and Boniface VIII, and are embodied in the canon law as Cap. 9 and 13 Extra, Lib. V, Tit. vii and Cap. 11 and 18 in Sexto Lib. V, Tit. ii.
When, in 1510, the jurats of Palermo made difficulties in taking the canonical oath, Ferdinand indignantly wrote that he would take it himself if required.—Arch. de Simancas, Inquisicion, Lib. III, fol. 134.
