First off, I want to preface this by saying that I am no expert on this subject, and so I feel highly unqualified in answering, however I have also looked into questions regarding angels and have found some interesting tid bits that may help you. So you may take this with a grain of salt, but I will share.
Here we go! First I think we must look at what the Bible actually tells us about angels. It is worth noting that, although they are important beings in scripture, we know painfully little about them. The little we do know comes from snippets and interactions between angelic beings and human beings.
One thing I believe we can surmise with complete certainty is that angels and humans are different. They are different at their core, they are different in their metaphysical and spiritual presence, and they are different in their role in God’s great creation. In Genesis we do not find out too much about their creation, which is not surprising because I do not believe it has any relevance to us, to our salvation, or to how we worship God or Christ. One thing we do know is that man was created in the image of God. So we know that we have this special bond between us and our Creator. When Satan entered the garden as the serpent, he had already fallen from God’s grace and probably had been banished along with his followers. So we see the angelic fall before the fall of man.
This is where we need to examine what we do know of the differences that are laid out in scripture. One of the best and most direct descriptions comes in Luke 20:35-36 when Jesus is responding to the question of who’s wife will the woman be who has had all seven brothers in marriage.
“but those who are considered worthy to attain to that age and to the resurrection from the dead neither marry nor are given in marriage, for they cannot die anymore, because they are equal to angels and are sons of God, being sons of the resurrection.”
Jesus tells us that when we die and enter heaven we will be equal to angels in that we will be immortal, and we will have no need for marriage and therefore procreation. We will also be sons of God. If we look at the implication of that title, we can see that we will be above angels in some way. First Corinthians 6: 3 tells us
“Do you not know that we are to judge angels? How much more then matters pertaining to this life!”
So we can see that right now as earthly sin-filled beings, we are beneath the angels, but we are set aside as being sons of God, and in our resurrection we shall govern the angels somehow. Hebrews 2:5-8 lays out that Jesus himself was made lower than the angels in order than he fulfill his Father’s will and be crowned with glory and therefore everything is in subjection under his feet.
So the view we get of angels as heavenly hosts in scripture is that they are messengers, they are ministers, and they are warriors.
They also do not marry, or procreate. Which I believe is a huge reason for the banishment of only the offending angels and not the subjugation of ALL the angels at the fall of Lucifer. There is no inheritance of evil from generation to generation of angels. They are individual beings, either angels of God or angels of the devil. And being that they are more metaphysical, if you will, they do not fall under the current dominion of man. They take on human form when they bring messages in scripture, but they are often completely unseen. Our given dominion is in this world. So when Adam and Eve plunged the world into sin, they procreated and passed on a sin nature that became inherent to all of mankind because it was engendered into our very being. The world was under our dominion so it too was ruined by our sin. The angels are outside of that because they are not like us at the very basic level according to what scripture tells us.
I have to admit, even as I finish writing this, we truly do know so very little about them. So most of what I say here is based on what little research I have come across on this subject. I have asked many questions about angels and mankind, and how they interact. But I suppose it is one of those wonderful mysteries that we shall be made fully aware of in our resurrected, new bodies.
