The perpetrators of the Inquisition – the torturers, informers, and those who commanded their actions – were ecclesiastics of one rank or another. They were men of God – popes, bishops, friars, and priests.

We must continually remind ourselves that there is a difference between what is natural and what is actually good for us.
