Those darn Jesuits
This is in response to dearime’s query about the Jesuits. I’m reinterpreting his remark that he found a “Jesuit’s candor remarkable” (or words to that effect) as “what’s the story with the Jesuits’ modernism?”
So “Modernism” is the intellectual movement in the Church to, depending on your point of view, bring Catholic theology up to date with modern science, politics and culture, or alternatively, to eliminate all or most of what is true in the Catholic religion and betray it to the forces of (in order of extremity) the Left, Marxism, Masonism, the Illuminati, and Satan. The Church is the ultimate big tent, though some might say it’s more like a circus fire.
Here’s the Wikipedia on Modernism in the Church. Various opponents of contemporary Jesuits here, here and here.
