E.A. Koetting in his Dixie State Seminar reports that King Paimon told him he was not going to be the one to heal E.A.'s daughter’s illness.
E.A. then worked with the Archangel Raphael on this, and did not lose his close working relationship with Azazel, who is stated in various texts as opposed to Raphael.
From personal experience, Raphael advised me to call upon the demon Marbas for one specific health issue. I have also witnessed Raphael communicating with Belial (sounded like birdsong) and Belial responding positively to this, NOT in some weird battling manner.
From even more personal experience, angels simply ARE, and are not beholden to any small tribal cult that happened to have a strange jealous “god.” 
To accept Biblical precepts as the final word is to have becomne a self-admitted believer that the Bible (and its various apocrypha) is THE truth. And I don’t find that to be the case at all.
Dogma is generally defined as preaching rote learning, and defending it from any kind of intellectual challenge or critical analysis based in experience, and observation… 
It is what it is - people, be they dark or light (to many of us,RHP/LHP mean something different), are capable of holding the dogmatic beleif that angels and demons are opposed and in eternal warfare, others of us find they work well together and that they did so for many millenia before a small desert cult tries to foist its pathologies on us all.
