It goes both ways on the Inquisition.
The documents were finally opened in August, 2003 by the wishes of P. John Paul II and it reaffirmed what Catholics already knew…that the excesses of the Inquisition were grossly exaggerated.
There were about 5,000 who died. But it was the Catholic clerics who did the most to work with them and to exonerate them. It was the temporal powers that executed.
The bigger context is that Spain was plundered for 700 years by the Muslim Moors. During the ‘Golden Age’ of Cordoba that Muslims always like to refer to, Christians and Jews had to wear green badges on the outside of their clothes, they were dhimmis, had little power of witness and trials, were not allowed to share their faith and bring others into the life of Christ.
So there was a revolution to break free of Islam and for the sake of national unity, to have one common faith. It is written that the Jewish population was oftentimes inciting trouble, and Spain wanted peace. I remember reading St. Theresa of Avila who tried to share her faith with a Jewish woman who was renouncing Christ.
Living in such an environment under Islam, and others having such an attitude about our Savior, it is understandable why Spain wanted to be a truly Catholic country.
And I give them credit for removing Islam power from its lands as well as Sardinia and Sicily in relation to Egypt, Palestine, and Syria who were once teeming Christian populations and then lost their faith.
