I've seen the uncreated God contrasted many times to the created angels, Satan, and humans, and etc. Being created is counted against the latter category as a mark of imperfection which God does not bear.
However I don't really see why being created is an imperfection. Surely something can be created and be created perfectly, right? To become perfect?
Is there a way to understand this through the bigger picture of what perfection is? Or is this something that must be understood on its own?
