I had this thought for a while but I finally have found a good way to do this.
So, an angel, functionally speaking, is a messenger/servant of the Judeo-Christian-Islamic God. I like some angels but I don’t believe in a higher divinity (perhaps a hidden power but nothing that transcends spirituality).
So I actually stumbled upon an originally fictional religion known as Earthseed. It’s relatively simple, and it’s first tenet is “God is Change”. As a LHP practitioner, and a student within the Draconian tradition, I see change as potential in all things. I desire stable, ever-winding change, that can be sped or slowed on command. If anything binds us together, it is a force of change, such as Chaos. Controlling change is the ultimate power. Interestingly, the second tenet of this Earthseed religion is “Shape God”. The Divine is what we make of it. (The third and final tenet is irrelevant here but it makes the entire religion a naturalistic religion)
So if God is Change, and angels are the messengers of God, and Change is Chaos… Angels are the messengers of our Change from Chaos!
