My problem is that no "ecclesiastical courts" should have ever existed. Nobody has the right to try another on the basis of faith. It was a disgusting period of history.
The Ecclesiastical Courts were for hearing cases of heresy being taught by Catholics. Only Catholics could be tried by the Ecclesiastical Courts. These courts were established to fight against various cults that had sprung up like the Albigensians, who claimed to have the correct interpretation of Scripture and came up with erroneous doctrines. Often Catholics followed these doctrines and tried to bring teach them as official Church doctrine.
This is all the Ecclesiastical Courts were established for. At the time of the Spanish Inquisition, they surpassed the state courts for fairness to the point that when the Spanish Inquisition was closed, people rioted in the streets for criminal cases would now be heard by the state courts alone.
The Ecclesiastical Courts mandated that the accused be represented by competent lawyers. The accused had a right to know all the charges brought against them, and to face the accusers in court. The accused also was allowed to have witnesses testify on their behalf.
The state court in 1500's Spain, had no such thing. As a result, people fought to have their criminal cases brought before the Ecclesiastical Courts and eventually that's what happened. When an accused was found guilty of their civil crime, they were sent back to the state, for punishment. This is why it was believed that the Church was hauling people before the Inquisition for various crimes, but it wasn't the court but the accused who sought to have their cases heard by the Church court.
The Jews who were brought before the Church Court, where those who claimed to be converts. In this time in France, being a Baptized Catholic bought social and economic benefits, and many falsely claimed to have converted to the Church, for this reason alone. The Inquisition sought to prove that they were in fact, Baptized Catholics.
We have to keep in mind what the culture was like in 1500's Spain. For instance, a man caught steeling a sheep, was sentenced by the state was to be disemboweled.
The Church did not execute anyone, only the state had this authority. Also, contrary to what we learned from British History Text, the level of torture used was no greater than that which cops used in the 1920's.
In fact, the prisoners at Guantanamo were tortured more severely, especially those prisoners who were sent to so-called Black Sites.
Were their abuses in the Spanish Inquisition ? Of course. Were the courts necessary ? Probably not, but we're judging with the hindsight of 500 years.
In all, historians now agree that no more than 2500 people were executed during the 356 years of the Spanish Inquisition and most were those who had their civil trials heard before the Church Court rather than the state court. In other words, they were found guilty of crimes against the state, not of heresy, which none were executed for.
