"NOBODY EXPECTS THE SPANISH INQUISITION!"
The Spanish Inquisition deserves neither the exaggerated praise nor the equally exaggerated vilification often bestowed on it. The number of victims cannot be calculated with even approximate accuracy; the much maligned autos-da-fé were in reality but a religious ceremony (actus fidei); the San Benito has its counterpart in similar garbs elsewhere; the cruelty of St. Peter Arbues, to whom not a single sentence of death can be traced with certainty, belongs to the realms of fable.
However, the predominant ecclesiastical nature of the institution can hardly be doubted. The Holy See sanctioned the institution, accorded to the grand inquisitor canonical installation and therewith judicial authority concerning matters of faith, while from the grand inquisitor jurisdiction passed down to the subsidiary tribunals under his control.
Joseph de Maistre introduced the thesis that the Spanish Inquisition was mostly a civil tribunal; formerly, however, theologians never questioned its ecclesiastical nature. Only thus, indeed, can one explain how the Popes always admitted appeals from it to the Holy See, called to themselves entire trials and that at any stage of the proceedings, exempted whole classes of believers from its jurisdiction, intervened in the legislation, deposed grand inquisitors, and so on.
