If a text claims to be from God, how do we verify that?

This is a fundamental question in philosophy of religion. Throughout history, many texts have appeared claiming to be from God — from major sacred books to small individual claims. How do we distinguish between what might truly be the word of God and what is of human origin? The question is not merely theoretical, but practical: millions of people build their lives on texts they believe to be divine. Therefore, verifying this claim is an essential matter.

Inadequate Responses to Avoid

From some believers:

"I feel in my heart that it's from God." Feelings are important, but they are not sufficient criteria alone. Followers of contradictory texts all feel the same way. Mormons feel the "inner testimony" for their book, Hindus feel the sanctity of the Vedas, and Muslims feel the miraculous nature of the Quran. Subjective feeling cannot be the sole criterion, otherwise all contradictory texts would be correct simultaneously.

"The text says about itself that it's from God, and that's sufficient." A clear logical fallacy (circular reasoning). Any writer can claim their text is from God. Self-assertion needs external verification, otherwise every text claiming divinity would be true by necessity — which is logically impossible when these texts contradict each other.

"My ancestors believed in it, so it's correct." The argument from tradition alone is insufficient. Every person is born into a different religious tradition, and inherited traditions contradict each other. If tradition alone were sufficient, no one could ever correct an inherited error or discover a new truth.

From some rejecters:

"All texts are human-made, without exception." A prejudgment without examination. Even if you consider the probability that a text might be divine to be slim, the scientific approach requires examining each case by its own criteria. Refusing examination from the start is not a rational position but a dogmatic one.

"Science has proven the impossibility of revelation." An inaccurate claim. Science studies natural phenomena that are repeatable and measurable. Revelation — if it exists — is not a repeating natural phenomenon, but a unique event. Science does not possess tools to prove or disprove the possibility of divine-human communication in principle.

Why These Responses Are Inadequate

The common problem is oversimplification or prejudgments. Some accept texts too easily, others reject them too easily. Serious verification requires criteria that are as objective as possible, with openness to different possibilities.

Serious Criteria for Verification

First, the criterion of internal coherence. A text claiming to be from a wise, all-knowing God would be expected not to contradict itself. Clear internal contradictions weaken the claim. But beware: what appears to be a contradiction might be a misunderstanding, so examination must be careful and fair, taking historical and linguistic context into account.

Second, the criterion of compatibility with established knowledge. A text claiming to be from the creator of the universe would not be expected to contain clear errors about the universe. But distinction is important between: (1) metaphorical or phenomenological language (like "sunrise"), (2) established scientific facts, (3) changeable scientific theories. Judgment requires precision and fairness.

Third, the criterion of moral and spiritual impact. A text from a merciful, wise God would be expected to elevate humans morally and spiritually. Does the text call for justice, mercy, and wisdom? Do its true followers (not mere claimants) show human elevation? This criterion is not decisive alone, but it's an important indicator.

Fourth, the criterion of linguistic/literary challenge. Some texts present themselves as linguistic or literary miracles (such as the Quran's challenge). This criterion is relatively objectively evaluable through comparative literary study, taking linguistic and historical context into account. Of course, literary inimitability (iʿjāz) alone doesn't prove divine origin, but it might be an indicator within a system of criteria.

Fifth, the criterion of fulfilled prophecies. If the text contains clear, specific predictions that were fulfilled in ways difficult to explain by chance or human wisdom, this is an indicator worthy of consideration. But caution is required against post hoc interpretations or vague prophecies open to multiple interpretations.

Sixth, the criterion of historical testimony. How was the text transmitted? What is the reliability of its transmitters? Are there independent historical witnesses supporting its claims? Reliable historical transmission doesn't prove divine origin, but questionable transmission severely weakens credibility.

A Cumulative Approach to Evaluation

No single criterion decisively proves or disproves whether a text is from God. The most rational approach is cumulative evaluation: examining all criteria together and seeing which way the scale tips. A text that excels in most criteria deserves serious consideration, even if it doesn't reach "absolute certainty."

Where We Stand in This Discussion Today

In the modern era, tools of textual and historical criticism have developed significantly. Comparative religious studies have become more precise and fair. At the same time, awareness has increased about the complexity of verifying religious claims. Serious scholars — believers and non-believers alike — tend toward epistemological humility: acknowledging that the issue is complex, that absolute certainty is difficult to attain, and that fair evaluation requires effort and study.
