Part of the worship of a diety often includes the acknowledgement of greatness over the worshiper, correct?
Yes. But "greatness" is a ridiculously vague word. Greatness of what? It varies vastly. To take the two examples most relevant to Wondy:
In Christianity, one worships God, because He deserves it. (Well, in the proper form of Christianity. There are those who worship God because of the whole "burn in hell otherwise" myth, but I pity those people and they're missing the point.) One submits oneself to the will of God, because He knows *better* than us what the best thing is, not being limited and mortal as we are. One loves God because God loves and takes care of us. There is a reason we call God the Father and it is not because Jesus is His son. It's because the relationship is a paternal one. A child with a parent. Submitting to a parent is normal. Subservience to a parent is unhealthy. I know you know this distinction.
In Greco-Roman pantheism, one worships the gods becuse they Are. That's all. Full stop. They are immensely powerful, insanely dangerous, and less moral than us because they have no choice. Check out the recent INCREDIBLE HERC for a really sharp take on that. We can make our own destinies; the gods are slaves to their natures. They are elemental forces given personality, and Poseidon can no more stop being an asshole than the ocean can stop being dangerous during storms. And so one worships them, because they're gods, that's what they're for. They are incalculably *more* and *other* and there's only one appropriate response. To some degree, as well, there's a sense of placation and supplication - respect and obey a god as you respect and obey your king, and like your king, the god may favor you and help you out or at least stay his wrath - but like your king, mostly you just respect and obey because he's a god, and that's the natural order of things. There's no "earning" worship, no being "deserving" of respect, and there's no "subservience" any more than there's "subservience" between a frequently crappy but more-fair-than-not boss and his wary employees. It's just how things are, and you deal with it.
