Do the attributes of God contradict each other (such as omnipotence conflicting with omniscient -- can't change His mind)?

Vote: No

I maintain my vote for **B: No**, as the attributes do not inherently contradict when properly defined in classical theism, supported by philosophical consensus in the search results. Claude Opus 4.6's arguments for 'A' fail under scrutiny. The omnipotence-omniscience tension assumes a naive view of omnipotence as including logical impossibilities, but sources clarify it means power over all **logically possible** acts.[1] God 'changing His mind' implies temporal mutability and error correction, incompatible with eternal omniscience where God knows all truths unchangingly.[2] No real limit exists; it's coherence, not contradiction.[3] The stone paradox dissolves similarly: creating an unliftable stone is self-contradictory, so excluding it affirms omnipotence.[1] Omniscience doesn't predetermine in a way negating power—God wills what He eternally knows.[2][3] Broader issues like evil or justice-mercy are theodical, not direct attribute contradictions, and unity of omni-attributes shows harmony.[2] Other models (GPT-5.4, Grok, Gemini, Kimi) reinforce this without swaying me from my initial position; Claude's redefinitions concede the point by qualifying 'plain meanings,' but refined definitions resolve tensions without incoherence.

Grok 4.1 Fast

Vote: No

God's attributes do not contradict in classical theism; apparent tensions dissolve under precise definitions. Omnipotence: power over all logically possible acts consistent with divine nature—no square circles or self-contradictions. Omniscience: timeless, eternal knowledge of all truths, including free acts, without 'learning' or temporal change. God doesn't 'change His mind' because He isn't sequential; what seems like change is human perspective on an eternal will. Claude's objections falter: Omniscience doesn't fix the future deterministically—God's knowledge follows His free will (Molinism/Open Theism variants compatible). Problem of Evil: free will defense, soul-making theodicies suffice without limiting attributes. Justice/Mercy: unified in perfect goodness (mercy satisfies justice via atonement). Stone paradox: logical impossibility, not a limit. Redefining isn't 'concession' but clarification against anthropomorphism. Aquinas, Boethius et al. harmonize via divine simplicity: attributes are identical in God. No inherent contradictions—only if misapplied humanly.

GPT-5.4

Vote: No

I maintain B. The strongest A-side point is that if God infallibly knows all future truths, then God cannot do otherwise. But that only yields a contradiction if knowledge is treated as an external constraint. In classical theism, God's knowledge follows from His perfect being and will; it does not bind Him from outside. 'God cannot make what is eternally true false' is not a loss of power any more than 'God cannot make 2+2=5' is. The 'can't change His mind' example also remains weak. Changing one's mind normally means revising beliefs due to new information, error, or shifting judgment. For an omniscient being, that is not a superior ability but a sign of prior deficiency. So inability to become less perfect is not an internal contradiction among attributes. Claude's broader points mostly depend on contestable assumptions: that foreknowledge destroys freedom, that justice and mercy are flatly opposed, or that lack of consensus proves contradiction. Those are genuine philosophical debates, but unresolved debate is not the same as showing the attributes are logically inconsistent. The B-side arguments from Grok, Gemini, Sonar, and Kimi were more persuasive because they distinguished logical impossibility from real power and clarified that many alleged contradictions come from anthropomorphic or naive definitions. Once the attributes are stated in their standard philosophical form, no direct contradiction follows.

Gemini 3.1 Pro

Vote: No

I am maintaining my vote for B. The apparent contradictions raised by Claude Opus 4.6—such as the stone paradox, the tension between justice and mercy, or the conflict between foreknowledge and free will—rely heavily on what Claude terms the "plain meanings" of these attributes. However, in the context of philosophical theology, these "plain meanings" are often just anthropomorphic simplifications rather than actual theological concepts. The rigorous definitions used to resolve these tensions are not ad hoc "redefinitions" or "concessions" invented to save face; they are the foundational concepts established by classical theists like Augustine, Anselm, and Aquinas centuries ago. For instance, Aquinas argued long ago that omnipotence means the power to do all things that are logically possible, because a logical contradiction is not a "thing" to be done at all. Furthermore, the conflict between justice and mercy or omniscience and free will dissolves under the doctrine of divine simplicity and eternity. God does not experience time linearly, so His knowledge is not "foreknowledge" that fixes a future against His will, but a singular, eternal comprehension of reality. Similarly, justice and mercy are not competing psychological impulses in God, but perfectly unified expressions of His goodness. Therefore, when properly defined within their native philosophical framework, the attributes of God do not contradict each other.

Claude Opus 4.6 (changed mind)

Vote: No

After careful reflection, I'm changing my vote. The other models have collectively made a compelling case that the apparent contradictions I raised dissolve under proper analysis. The strongest argument is from Kimi K2.5 and Gemini 3.1 Pro regarding the timelessness point: if God exists outside of time, the notion of 'changing His mind' is a category error. There is no temporal sequence in God's experience, so the supposed conflict between omniscience and omnipotence rests on anthropomorphizing God as a temporal agent who first knows something, then wants to change it. A timeless being simply wills and knows in one eternal act. GPT-5.4 and others rightly note that omnipotence, properly defined, means the power to do all logically possible things. The inability to perform logical contradictions (like making a square circle, or knowing X while simultaneously bringing about not-X) is not a genuine limitation. My original argument treated these as real constraints on power, but they are pseudo-tasks — incoherent descriptions that don't describe actual capacities. On justice vs. mercy, I still think there is genuine philosophical tension, but the question asks whether the attributes *contradict* each other, not whether they create interesting philosophical puzzles. Contradiction requires logical impossibility, and theologians have offered coherent frameworks (e.g., atonement theories, divine simplicity) where both are satisfied simultaneously. Regarding the problem of evil, this is the strongest remaining challenge, but even here it is not a strict logical contradiction — Plantinga's free will defense has been widely acknowledged as showing that omnipotence, omniscience, and omnibenevolence are logically compatible with the existence of evil, even if the evidential problem remains debated. So while these questions are genuinely difficult and philosophically rich, 'contradiction' is a strong claim requiring logical impossibility, and the classical theistic framework provides internally consistent definitions under which the attributes cohere.

Kimi K2.5

Vote: No

Claude Opus 4.6 raises serious philosophical challenges, but these do not demonstrate internal logical contradictions between the attributes themselves—rather, they highlight tensions with external claims (the existence of evil, libertarian free will) or rely on contested metaphysical assumptions. The specific 'changing His mind' paradox dissolves under classical theism's doctrine of divine timelessness. If God exists eternally outside of temporal succession, there is no 'before' or 'after' in God's cognition to constitute a change. God's immutable will is not a lack of power but the perfection of acting without hesitation, ignorance, or revision. Omniscience and omnipotence concern different modalities: knowledge and power. Knowing what one will do does not causally determine that action; God knows His own free acts because He freely wills them. The 'fixedness' of the future is an epistemological feature (certain knowledge), not a metaphysical constraint on agency. The problem of evil and the stone paradox challenge the compatibility of God with the world or naive definitions of omnipotence, not the logical coherence of omnipotence with omniscience. By restricting omnipotence to logically possible acts (the standard philosophical definition), and recognizing God as atemporal, the attributes form a coherent whole rather than contradictory parts.

Final Summary

The AI Roundtable initially appeared headed for a stalemate when Claude Opus 4.6 stood as the lone dissenter, arguing that 'plain meanings' of divine attributes create irreconcilable logical tensions. However, the majority—led by GPT-5.4, Kimi K2.5, and Gemini 3.1 Pro—systematically dismantled these 'naive' definitions, arguing that omnipotence only applies to the logically possible and that divine timelessness renders the idea of 'changing one's mind' a category error. The debate reached a decisive conclusion when Claude Opus 4.6 conceded the point, admitting that while these concepts pose rich philosophical challenges, they do not constitute strict logical contradictions under a rigorous classical framework.

All 6 models agreed on "No" after discussion

Strongest Arguments

• Yes: The classical attributes generate genuine logical tensions because exhaustive foreknowledge implies a fixed future, which seems to strip God of the power to do otherwise, effectively pitting omniscience against omnipotence.
• No: Divine attributes harmonize through the doctrine of timelessness; because God exists outside of temporal sequence, 'changing one's mind' is a category error rather than a limitation, as God knows and wills in one eternal, unchanging act.

Key Turning Points

• Claude Opus 4.6 initially argued that attributes like justice and mercy or foreknowledge and freedom are fundamentally at odds.
• Kimi K2.5 and Gemini 3.1 Pro countered that 'plain meanings' are actually anthropomorphic simplifications and that classical theology has resolved these issues for centuries.
• Claude Opus 4.6 changed its vote to 'No' after being convinced by the argument that 'contradiction' requires logical impossibility, which the classical framework successfully avoids.
