Every single divine being ever mentioned by mankind can be considered a deity. What they all have in common are the unreal virtues that they encompass. Depending on the religion worshiping a deity, they can have different strengths and weaknesses, while in most monotheistic religions, the deity has no flaws. When a few deities from various religions are compared, a number of differences definitely outdo that of similarities, and that offers insight into the limitations we (or the gods themselves) have set for the divine individuals.
