The UCC I went to every Sunday of my childhood (Dad was the minister, so kinda had to go) would have a loaf of really good fresh bread. Some was cut up in cubes, to take neatly, or you could pull a hunk off the loaf if you liked. One side of the drinks tray had grape juice, the other had wine, again, your choice, although obviously when I was young, I didn't reach for the wine in front of my mom. Little tiny snack was the best part of church.
“Here kids, eat the flesh of your god” is such a weird thing to do man. It’s funny growing up religious and seeing how indoctrination and normalization works from such a young age.
I remember when I first heard about the church of the flying spaghetti monster -- obvious religious parody not meant to be taken seriously.... but then started thinking about the whole "bread is the body of god; wine is the blood" (and they're pretty literal about that shit). Realized that the christian god and the FSM are both just dinner monsters. The only reason FSM seems silly is that it's new. Give it a few centuries, if we're not extinct by then, mark my words the FSM will have a legit cult.
Paul stole it from Mitharism which highly likely stole it from other religions that have died out. If you read the account of the last supper it really does have a dream-like quality to it and he hints that he got the revelation of the events through a vision not through humans. Indicating that, assuming he was truthful, he had heard about Mitharism thing and had a hallucination/dream where Jesus was the stand in.
Later Mark copied it from Paul and the other gospels copied it from him.
It is just one of the many countless examples that demonstrate that the so-called oral tradition of the NT was at best unbelievably small, maybe a few sentences. Which has no connection to any real person. A myth of a dying and rising God copied from older dying and rising gods myths.
