You posted those quotes as if to provide some kind of reasoning behind the Catholic view that demons are fallen angels. I'm just pointing out that this is not the case.
It's not a big assumption and nor does your proficiency with the subject matter really factor into it.Also, making statements such as is a big assumption considering I am just a novice on the topics.
I don't like to brag but I'm pretty up on my bible and I know that there's not anything in there that directly supports the angel theory because I've researched it.
I'm open to the idea that I may have missed something but, to my knowledge, there is no biblical backing for this idea.
Now, if the Catholics have their own dogma outside of the bible that supports it then that's their business and naturally I would not have read it.That also reminds me to take into consideration the documents written by what many consider 'saints'.
