Because they said it was a Thursday thing. And if there's a Thursday thing, then there's a Wednesday thing and there was a Friday thing. I know this is the show of Sam-hane and man-eating Ganesh, but seriously. Do they throw darts to make these decisions or what?

I like things.

I know a couple of Dictionary of Angels reference books I have list Castiel as the angel of Thursday. No other information or explanation, just that.

And when I get home, I can check those books to see if they list an angel of any other days of the week.

I looked up the book that the supernatural wiki points to, but it's unclear that they don't also list every single angel as angel for any given day. What I'd understood was that Castiel was an error for Cassiel, and Cassiel was the angel of Thursday, but he's much more popularly the angel of Saturday. Very little uses the name Castiel, and very little ties him to Thursday.

Pretty much just this book as far as I can tell.

... okay, if no one hears from me for a few days, it's because I've fallen down the rabbit hole of searching out esoteric angelic information. That sort of thing ALWAYS sucks me in. (Which is probably why when Show started showing Enochian writing, I got cranky about how they were Doing It Wrong.)

Anyway, according to some quick searching, Anael, Sarquiel, Sacquiel are possibly angels of angels of Friday, and Michael, Gemi, Sabael, Sarpiel, Muriel are possibly angels of Wednesday. Maybe.

Ha! That's the book I have at home. And let me tell you, it's a lot easier to find a clear hierarchy of demons than of angels.

I'm impressed by the fuckit attitude many authors have to Enochian. Like, I wouldn't include it in story or art, because I don't know what rules the show is following (that they might have made up) or what's actually the right answer.

But, damn, there is a whole lot of "Akzh Eppha Pitzle!" said Castiel, and summoned a cherry pie.

I think this is where I realize I'm more like Dean, because ... angels aren't real. And the conflicting accounts of which angel belongs to which day isn't any more surprising than all the other pieces of Biblical lore told and retold by different authors that contradicts itself.

I guess, for me, there's never going to be any one way to make it right (although a nod from the writers is always great -- yes, we meant to say he really is the angel of Thursday) so I make my best guess based on available information and what pleases me most.

A best guess on available information doesn't get you to Castiel, usually. So extrapolating from that is unsatisfying. If that was the predominant "answer", then the corresponding Wednesday guy being Raphael would trigger a couple bunnies for me. Hell, it's Assiel or Buttiel, there's somewhere different to start.

But if your axioms have no basis, you can't make any deductions. Just creation. Which is a different thing.

If the show said there were 17 archangels, and the most important of them was named Cathy, then...not an arena that's interesting for me to speculate in, since everything is equally true and untrue at the same time.

I probably should have said I just don't care that much, I guess? I love it when something in a show or a book is based in fact, but Castiel's official role in heaven doesn't really mean anything to me in the larger scheme of things.

Although I would like to know what an angel of Thursday does. Protect Thursday? Protect children born on that day?

Also, isn't "Castiel" (the word) used in a S1 or S2 episode when they're doing an exorcism or something? I could swear it was, which makes me wonder if it was just a cool-sounding word/name they ran with.

Found it on SuperWiki: "Castiel's name is first mentioned in the Season 3 episode 3.06 Red Sky At Morning during the graveyard scene where Sam reads aloud a summoning ritual from his father's journal. He speaks the names of several angels during the ritual, and one of them is Castiel."
