This is spin. Saying the Inquisition was “fair for its day” is like saying the Holocaust was “fair for Nazi Germany” or that slavery was “fair for the US in the 1700’s.”
OK, then try listing five things in Nazi Germany worse than Holocaust, or five things in USA in 1700s worse than slavery.
I’d say that the things you listed at least arguably are the worst things about those societies.
Thus this your comparison doesn’t work.
It was wrong, wrong, wrong, period. Excusing it even a little is unconscionable.
Wouldn’t it be better, if that was a conclusion, and not a premise?
This attitude prevents us from actually finding out what went wrong and why. And from avoiding that in the future.
But yes, it is much more convenient to just proclaim that “they” were evil without looking too closely, and to pretend that “we” are obviously better, immune to whatever temptations “they” had.
And the information from the Vatican archives comes from Catholic sources, who were biased toward defending the Church.
And the anti-Catholic sources are to be presumed to be impartial and infallible?
I’m talking about the Church authorizing atrocities, including torture specifically authorized by a pope, burning at the stake, etc.
OK, so perhaps we should start by finding out why those things count as atrocities? For example, are you saying that burning on stake was wrong, because it was a death penalty, because it was a bad method of death penalty, because innocents were being executed? Any of these positions seems to be arguable, and it would be nice to know which of them is yours.
