Divine Jealousy

As the uncaused cause, God is superior to all other beings, even hypothetical beings created with all of the same power and intentions other than the fact that they did not always exist past-eternally.  The metaphysical initiator of the causal chain that produced all contingent things (not himself, the laws of logic, or empty space), and the only being whose nature could ground morality if it exists, God does not have to be the Yahweh of the Bible to be the ultimate being.  The laws of logic are more foundational as necessary truths than even he, but the uncaused cause is above humans as humans are over insects.

This is true whether or not it is the deity of Christianity.  Either way, these truths are relevant to the nature of the Christian God, who calls himself by the name Jealous in Exodus 34:14.  This is said in the context of condemning the worship of other gods or toleration of affiliated practices.  Yahweh outright identifies himself as a jealous deity here.  What does this mean and not mean?  Jealousy, as common as it appears to be, particularly among non-rationalists, is for all of its popularity not always perceived as a positive trait.  In fact, it destroys relationships by acting as a barrier to everything from personal peace to interpersonal stability.

Yahweh's attribute in question is not the petty jealousy of someone who thinks their significant other should never be attracted to anyone but them or who panics at the thought of someone else being attracted to their partner.  Rather, it is the disposition of a being whose nature is so much higher than that of humans and other metaphysical entities that to give equivalent (or sometimes any) allegiance, submission, or love to the other beings is itself a great irrationality and sin.  To reuse a similar human example, a jealous spouse might be enraged or offended by something that is not even immoral, like their partner being sexually admired by others, but with God, there is no other being who could deserve anything apart from him because there is no right or wrong aside from his nature.

Divine jealousy in the Biblical sense is far from petty, selfish, and asinine.  If the uncaused cause has no moral nature, no one deserves anything, not even God, and there is nothing morally right or wrong about any attitude like jealousy in any of its forms.  No person would deserve to be spared from divine jealousy in this case.  If the uncaused cause does have a moral nature--and an uncaused cause exists regardless [1]--then its characteristics and will are good no matter what any other creature prefers.  God's jealousy is literally the only kind that could possibly be valid as a basis for expecting behaviors from others.

Yahweh is the only being that has an inherent right to be jealous if he is the real uncaused cause.  Far from making him stupid or volatile, this would necessitate that one's supreme allegiance (other than to the logical truths that make Yahweh's existence and nature possible in the first place) should never be given not only to false deities or lesser spiritual beings, but also to other people or oneself.  As far as beings are concerned, there are none higher or more foundational than the uncaused cause.  God could not be immature or irrational for demanding proper recognition on these grounds.
