If I'm not mistaken, Paradise Lost is the original source for much of it, and more recent popular culture embellishment is much of the reset. Essentially the line "Better to reign in Hell than serve in Heaven" is split in half, and the focus is put on "than to serve in Heaven" as a rallying cry for independence, and the "better to reign in hell" part is ignored. The Satanic Temple doesn't worship (or believe in) Satan, so leaving off the other half is inconsequential as he's just a symbol anyway.
