Are Christians allowed to eat on Good Friday?

Completely depends your age, how strict you/your family/your congregation follow the rules, your church, and even your denomination.

Catholics, for example, have the rule that Ты are supposed to fast completely on Good Friday, but only if you're over 18. If you're over 14 (but not 18), Ты don't have to fast, but Ты can't eat meat. But, I've belonged to two separate Catholic congregations, and they were never strict about the fasting. Their thing was not eating meat on Fridays.

I have an aunt that's Baptist. Her first church didn't celebrate Good Friday at all. Her секунда church did, but followed it loosely. They didn't fast, but they didn't eat meat either.

Well I'm allowed to eat but I can't eat meat

all i know is Ты can't eat meat and i think Ты can't drink alcohol i'm not too sure on that alcohol thing i could be wrong but Ты are allowed to eat on good friday

Of course Ты can eat! True, it is a special day, but Иисус cares about your physical needs. If you're hungry, he WANTS Ты to eat.

we can. but for me, its a "fish" day.
