Hmm....Can’t say I know what an A&P Catholic is. I know C&E Catholics (Christmas & Easter)....
Ash Wed. / Palm Sun. (a quick google turned it up)
The priest at my church refers to these as HMDs, e.g., “hatch, match and dispatch” folk. Occasionally, they even make the Easter service.
According to the Urban Dictionary:
“”Catholics (or any form of Christianity, basically) who only goes to Church on days when they give out free stuff; namely Ash Wednesday and Palm Sunday.
“Bob: Do you ever go to Church?
Steve: Only on Ash Wednesday and Palm Sunday, when they give out free stuff.
Bob: Dude, you are such an A and P Catholic!””
I am not sure that I believe this. Ashes and palm fronds don’t have much value.
The folks who show up for "giveaways" - Ashes & Palms.
I know C&E Catholics (Christmas & Easter)....
I had forgotten that expression. In this instance, I intended it to mean (First) Communion & Weddings. They also appear at Confirmations ; - )
