I know everyone has their own interpretations of एंन्जल्स but in terms of Supernatural, are all एंन्जल्स actually related या do they call each other brothers and sisters for another reason? I'm sorry if this सवाल is stupid.

It's definitely not a stupid सवाल !

They aren't literally siblings, because they weren't literally born, they were created. They all have the same creator, who is to them their father, since एंन्जल्स do not physically breed. Although this doesn't mean he's not "really" their father, because this sort of father-child/creator-created relationship is much और powerful and real to एंन्जल्स probably than how some humans consider God to be their "father." एंन्जल्स exist in a spiritual way, and a spiritual connection is probably और important than a genetic one. I don't think the एंन्जल्स even have any genetic material, until they possess a human vessel, they exist on a spiritual plane. In this sort of situation the concept of what is a parent या sibling becomes much और abstract, and whether एंन्जल्स are actually siblings depends on how literal your definition of the word is. However I think the एंन्जल्स consider eachother to be their brothers and sisters.

That's my take on it.

I think its like a respect thing.

What that means is as christians & followers of christ we are all related for God is are creater he is are father in heaven so that makes all of us brothers & sisters in Christ. Talk about your Big families!
Hope that didnt confuse आप to much,

They're actually related -- although there are so many of them that I doubt they've all met each other .. they ARE all brother & sister. :)
