Q, Thank you.
Praying in agreement with you.
For God and Country.
"With You, Jesus, we are safe. Amen"
Angels are created by God as Spiritual beings.
They can not incarnate. (Not allowed) But, they can manifest for short time if God wills to help us.
We're told in the Bible,the dark angels, left their first estate and bred with the daughters of men.
They're damned forever. God does not have a redemption plan for them leaving His Presence.
The book of Enoch gives more details about it. But I question the legitimacy of the copies of that book in modern times being corrupted.
