Apart from what swordofop said, I believe Authorities are granted by the Witch Factor who has something resembling a consciousness.

Taking into account Petelgeuse seems to have a very ingrained relationship with the Witches and might be the founder of the Original Witch Cult, he also mentioned Flugel when he forced the Witch Factor of Sloth into granting him his Authority.

I believe Flugel somehow managed to reprodude the Witches Will or inherent power that stemmed from their pasts into this artificial consciousness that is the Witch Factor, binding into a user and granting him the original Witch's power depending on the persons compatibility with it.

Flugel might've made them, and now theyre free for the taking, but there seems to be some kind of process involved as Regulus stated that Petelgeuse forcing his Witch Factor into him was a gross insult to those who went through the "due process" to achieve their seat as Archbishops of Sin.
