I’m going NO. Oysters grow on dead trees almost always. They do NOT cup upwards like this. They may be edible (I wouldn’t eat them), but they are not tan/white oysters in my opinion (and I’ve collected and eaten a LOT of white/tan and golden oysters).
Serious question, can’t the bankruptcy court force this, and all the diocese that are doing the same thing, to claw back the money they’ve sent Rome in the last 10, 20, or however many years?
