Serial Mom, despite her faults, always said her prayers, went to church, and most importantly, she recycled. News today is that the Vatican has come out with "new sins", among them, not recycling. Full story here. (Truly, there are no "new" sins, although new developments in technology and science may warrant pointing out practices that are sinful in application or omission, things some people wouldn't otherwise think about.)
The "new" deadly sins are: "Genetic modification, carrying out experiments on humans, polluting the environment, causing social injustice, causing poverty, becoming obscenely wealthy and taking drugs are all mortal sins."
Thus, I suppose one might say, "not recycling" is a sin because it leads to "polluting the environment" or something. I would love to have to confess "becoming obscenely wealthy," especially if I couldn't help it - although if it was against my will, it wouldn't be a mortal sin. I just threw out all of my prescriptions now that "taking drugs" is a mortal sin. (I should be dead in a week. LOL!)
I'm thinking not wearing a seat belt is already a sin - but I'm not sure about white after Labor Day - The Pope wears it all year long you know.
