I believe in angels. I even believe in personal Guardian angels (a Catholic teaching kept). I believe in Gabriel and Michael. I believe in multitudes more though I have no idea what their names are. However, Tobit is a fictional book so Raphael could be real or a literary tool. I don’t believe there is enough evidence to say one way or another with him.
I trust the Church in telling us that, yes, Raphael is a real angel 
And remember, the name means “God heals.” So, keep that in mind the next time you read Tobit. It may give the book a whole new meaning.
Satan or Ha Satan (accuser or the accuser) is an angel fallen. Scripture pretty clear about it. When Jesus rebukes Satan pretty clear that there is an enemy there. No argument from me there. However, it is interesting to note a greek title for him, Lucifer, in christianity. Lucifer ( in greek mythology) is the morning star. The last one that could be seen at dawn when the other stars have disapeared. The light of the sun eventually makes that star disapear. Greeks believed that this was a god who was chased away by Apollo. That doesn’t mean I don’t think there is a real Devil. I do. I just find it interesting about the greek referrence.
The Greek name for Lucifer is Phosphoros which translates from the Hebrew *Helel ben Shahar *in Isaiah 14:12, and when the Greek was translated into Latin, Jerome used Lucifer:
“How you have fallen from Heaven, O Lucifer, son of the morning!” The verse was interpreted by Christians as a reference to “Satan,” because of the mention of a fall from Heaven, even though it is literally a reference to the King of Babylon.
There are protestants who think the Catholic church is to blame for everything and that the Pope is the Antichrist or that it’s the “whore of bablyon” These are carryovers from the difficult reformation period.
…but have been perpetuated as christian fundamentalism has increased.
