A note on that I’d like to add: a pre-modern view in various cultures, including Roman and Greek cultures, is that the Gods are seen as all-powerful, if we define powerful as “having the ability to influence or exert power over the World”. In Platonism, the Gods exist beyond time and space (See: Plato’s ‘Timaeus’), and are the highest in the chain of being - That is, They are the ultimate causes of all, everything descends from Them. We see how in that view the Gods are beyond power entirely.
A general view among Mediterranean polytheistic cultures and many beyond is that the Gods are the governors of the World.
Being influenced by Platonism, among other philosophies, I personally believe that myself - That They are all-powerful. I’ve worshipped many Gods (Well known and little known) and I can’t say one is more powerful than the other.
Here is one Stoic excerpt on the Gods, that may be of interest:
(The Stoics say) that a god is an immortal, rational (logikon), perfect or intellective (noeron) living being (or ‘animal’, zōion) that is in a state of happiness (en eudaimonia) and does not admit of any evil, and which is providential over the cosmos and the beings in the cosmos. And it is not human-shaped (anthrōpomorphon).
