We need new words for our madness.
I disagree. I think we just need to not be afraid to use old words like “sin”, “avarice”, “bearing false witness”, “selling the needy for a pair of sandals” and other clear and unambiguous language. We haven’t come up with new sins. We’ve merely lost the guts to use the right words to describe them. It’s one of the principal ways sin makes you stupid.
