This leaves the question begging: by what authority did this alleged church kill or imprison anyone?
The authority of the Inquisition was only over those baptised Catholics -- it did not prosecute more than 120 Protestants for the simple reason that there were hardly any Protestants in Spain -- it was not popular, being regarding as more a Germanic thing. There were 120 who were executed -- and that was 120 too many, but that is a small number compared to the rest of the religious wars fought in the same time period -- and remember that among those called Protestants - "Most of them were in no sense Protestants...Irreligious sentiments, drunken mockery, anticlerical expressions, were all captiously classified by the inquisitors (or by those who denounced the cases) as 'Lutheran.' " ---> we would not call such people Lutheran today
