"Fish on Lent" is supposed to be an act of humility, as it is historically a peasant dish.
"Eggs on Lent" is appropriate not because "eggs aren't chickens until they're hatched" but because eggs are cheap.
Of course, with the price of fish diverging heavily from meat in the wake of factory farming, one might rationally argue that the American lental feast should be burgers.
But this would not be the first time that the dogma of church history outweighs the message they're supposedly teaching.
I smell the BS from here and I haven't heard a single bell for 4 years living in Kenmore Washington. Actually I have to say that I haven't seen a single Catholic church nearby. Maybe I need to Google them and they do exist. But man it's soo reassuring not having to be part of any of that BS.
