Joseph Smith’s Prophecies — The Deuteronomy 18 Test
Critics list eleven prophecies of Joseph Smith that supposedly failed — and cite Deuteronomy 18:22 as the biblical test for a false prophet. The argument is serious and deserves a serious answer. Here it is.
The Argument
Deuteronomy 18:22 states: “When a prophet speaketh in the name of the Lord, if the thing follow not, nor come to pass, that is the thing which the Lord hath not spoken, but the prophet hath spoken it presumptuously: thou shalt not be afraid of him.”
Critics apply this passage as a mechanical checklist and then list alleged failures:
Alleged Failed Prophecies
- D&C 87 — Civil War prophecy: critics claim all nations were required to be involved; they weren’t
- D&C 84:4–5 — Missouri temple not built within Joseph’s generation
- U.S. Government — overthrow of the United States government
- D&C 111 — Salem, Massachusetts treasure
- Canada — Book of Mormon copyright in Canada
- W.W. Phelps — prophesied to live until Christ returns
The argument sounds devastating until you apply the same standard to the Bible. Then it collapses entirely.
The Response — Three Categories
Category 1: Conditional Prophecies Where the Condition Was Not Met
Does the Bible contain prophecies that did not come to pass? It does — and every serious Bible scholar knows why: conditionality. The clearest example is Jonah. He prophesied Nineveh would be destroyed in forty days. It wasn’t. Nineveh repented, God relented, and no critic of Joseph Smith calls Jonah a false prophet. Jeremiah’s prophecies were modified when circumstances changed. Joel’s have not all been fulfilled. The conditional nature of prophecy is not a Latter-day Saint invention — it is a foundational principle of biblical prophecy itself.
“Yet forty days, and Nineveh shall be overthrown… And God saw their works, that they turned from their evil way; and God repented of the evil, that he had said that he would do unto them; and he did it not.”
D&C 84:4–5 states the temple in Missouri was to be built “in this generation.” But verses 31–32 establish a covenant the Saints were required to keep. Section 101 and Section 124 explicitly record that the Saints failed to keep that covenant — and the Lord explicitly released them from the original timetable as a consequence. This is not a failed prophecy. It is a conditional prophecy where the condition was not met by the people, not by the prophet.
The Gospel of Jesus Christ teaches that covenants are bilateral. When the people break their side, the promised blessing is deferred — that is not prophetic failure; it is prophetic precision.
Category 2: Prophecies That Were Fulfilled — Critics Misread the Conditions
D&C 87 is the most famous example. Joseph Smith prophesied in 1832 — thirty years before it happened — that war would “commence in South Carolina.” It did. Fort Sumter, April 1861. That alone is remarkable. No informed critic disputes it.
The objection shifts to the phrase “poured out upon all nations.” Critics read this as requiring every nation on earth to formally enter the conflict. That reading is forced. The text says the war would be “poured out upon all nations” — not that every nation would send troops. Britain came within days of military intervention. France was involved in Mexico during the conflict. The global cotton economy collapsed. The geopolitical reverberations were, in fact, worldwide. More significantly, D&C 87:5 predicts that “the remnants who are left of the land will marshal themselves” and that “the remnants shall vex the Gentiles” — a prediction of ongoing racial and social conflict in America whose arc has not yet concluded.
The question is not whether Joseph’s description matches a CNN checklist. The question is whether, taken as a whole, the prophecy demonstrates foreknowledge no 1832 human possessed. It does.
Category 3: Context and the Purpose of the Deuteronomy 18 Test
The Deuteronomy 18 test must be read in its original context. It was issued to a people surrounded by nations whose prophets and diviners spoke in the names of false gods — Baal, Asherah, Molech. The test was designed to identify prophets who claimed to speak for Jehovah but actually served other powers. Read Deuteronomy 13 alongside it: that companion passage says even a prophet whose signs come to pass can be false if he leads people away from God. The test is not a mechanical checklist of fulfilled predictions. It is a test of prophetic source and allegiance.
Joseph Smith himself distinguished between “Thus saith the Lord” revelations recorded as canonized scripture and his own inspired commentary and opinion. The Canada copyright incident and the Salem treasure episode are not recorded in the Doctrine and Covenants as “Thus saith the Lord.” Elevating informal statements to the same authority as canonized revelation is a category error — and it is the critics who are making it, not Joseph Smith.
No prophet in the Bible — not Peter, not Paul, not Isaiah — had every informal statement they ever made treated as binding canonized prophecy. The standard is invented specifically for Joseph Smith and applied nowhere else.
The Ironic Test — Apply It to the Bible
Apply the critics’ mechanical Deuteronomy 18 test to the biblical prophets:
Biblical Prophecies That “Failed” by the Same Standard
- Isaiah 13:20 — Babylon would be so destroyed it would “never be inhabited” — Babylon was inhabited for centuries afterward
- Ezekiel 26:14 — Tyre would be destroyed and “never be built again” — Tyre was rebuilt and exists today as Sur, Lebanon
- Matthew 24:34 — “This generation shall not pass till all these things be fulfilled” — the disciples’ generation passed; critics interpret this as a failed prediction
- Jonah 3:4 — “Yet forty days, and Nineveh shall be overthrown” — it was not overthrown
No critic of Joseph Smith applies Deuteronomy 18 to Isaiah. None demands that Ezekiel be rejected as a false prophet because Tyre was rebuilt. None dismisses Jesus as a failed predictor because “this generation” passed. They interpret these passages with nuance — recognizing conditionality, figurative language, layered fulfillment, and original context.
They then turn to Joseph Smith’s prophecies and apply a mechanical literalism they refuse to apply anywhere else. That is not a standard. It is a double standard — and a double standard is not a refutation.
Verdict
The Deuteronomy 18 test, applied consistently and with its original conditional and contextual meaning, does not disqualify Joseph Smith. The specific prophecies critics list fall into three categories: conditional (deferred because the covenant people failed, not because the prophet was false), fulfilled (properly read on their own terms), or informal statements elevated to canonical status they never claimed to have.
The same standard applied to Isaiah, Ezekiel, Jonah, and Christ would require rejecting them. No honest critic accepts that conclusion — which means the standard is being applied selectively. Selectively applied standards are not honest standards. They are arguments dressed as standards.
Joseph Smith’s 1832 Civil War prophecy alone — naming South Carolina thirty years before Fort Sumter — is a datum that demands explanation. The critics have never provided one.
