Hello.

Does someone know Christian books with disembodied spirit or angel as hero?

I'm looking to make it into a list.

Thanks.

A Secret Cavalry the series.

I mean disembodied spirits or angels who are, and remain, faithful to Elohim Yhwh.
From the first book's description, the angels there act on their own volition to meddle with humans and force Elohim's permissive will to "save" people...?
Also they need human vessels.

These traits are known to be that of fallen angels according to the history of Genesis; rebels who have no longer the ability to materialise themselves.

Faithful non-human angels supposed to interact with our world are strict professionnals sent for precise duties...they have clearance and ability to form their own body if they need to interact with our material world. They haven't lost thaynt right for ruined the human dna.

Faithful post-human angels from The House of Yhwh, of The Holy Spirit: The Bride, might use human vessels because they act only as a collective of which the vessel is a part...
But they would never go against Elohim Yhwh's permissive will regarding human beings.

I can confidently say, these angels are the heroes they are because they don't rebel against their creator. I'm writing this series because of the lack of stories where angels are actually being angels. The drama comes when their hosts fall short and need a helping hand. In my story the angels are A Secret Cavalry.
