So, you adhere to the Thomasists concept of maximal greatness? (Not every Theist does.)
Never heard of Thomasists. I looked them up, and I'm not sure they're the ones you're thinking of. I could be wrong, though. Regarding maximal greatness, I looked that up too. ( Apologies, I'm not too interested in proving God. I actually think that's counter-productive. )
I'm not sure "Maximal Greatness" describes my concept of God. I go with: infinite, eternal, solitary before creation, and tri-omni.
If we can agree that the god you refer to is of limited omnipotence, there is still room for rational discourse.
I m saying that omnipotence requires the capability to limit its omnipotence temporarily. Otherwise, that is a potency which is lacking. It's like the silly video I posted from the 90s movie "Revenge of the Nerds 2". Infinite includes big and small. Omnipotent includes all capabilites, including limiting itself, or even destroying itself.
And yes, I am aware that this challenges the idea of God's immutability. But, that isn't really a problem. The verses which claim "God doesn't change" in context are all talking about not revoking a promise to do good. The most famous verse regarding this is in Malachi. Commenting on this verse, the Baal Shem Tov, a great Jewish thinker and mystic, objects to the common understanding asking, "Isn't God the master of change?"
In my experience there are many theists who reject logic for the opinion of an all powerful god that defies logic. And I can't reason with someone who rejects reason.
Reasonable people have reasons for their conclusions. People with integrity admit when they're at fault, and acknowledge when someone makes a good point. I can't promise that any valid reason given which challenges my own conclusions will over-rule my own reasons for developing that conclusion. But I do strive to be both reasonable and to have integrity.
My reason for rejecting the "rock is too heavy" and "buritto is too hot" contradiction is because omnipotence includes the power to reduce itself temporarily.
My reason for rejecting the "that's not omnipotence" challenge to the definition is simply to refer back to the defintion of omnipotence, and that denying this power to limit itself, is itself a denial of omnipotence.
If you can convince me that "limiting itself temporaliy" is not a power, a potency. Then you will have convinced me that I am contradicting the definition of omnipotence.
Do you have any reasons for claiming "limiting itself temporarily" is not a power?
Next step: can your god defy the laws of nature?
I vote: yes, whole-heartedly. That is the definition of a miracle. What's next?
