A logical proof that Mormonism is false

by Matt Slick

Mormonism teaches that God used to be a man on another world, (Mormon Doctrine by Bruce McConkie, p. 321) and that he became a god (this is called exaltation, Teachings of the Prophet Joseph Smith, pages 345-347, 354) and came to this world with his goddess wife.  He was able to become a god because he followed the laws and ordinances of the god he served on another world.  That god, in turn, was exalted by his god, who was exalted by his god, ad infinitum.  In other words, there is a progression of gods being formed as far back as you look in time.

Truth does not contradict itself.  If I gave two statements about a subject and the two statements contradicted each other, then you would know something was wrong.  The law of non-contradiction states that something cannot be both true and false in the same sense at the same time.  In other words, truth does not contradict itself.  This is basic logic.  That which is true is internally consistent and contains no logical impossibilities.  If something does contain a logical impossibility, then it cannot be true.

Mormonism teaches an infinite regression of causes.  This means it teaches that each god was made a god by a previous god.  This further means that as far back as you look in time, this process has always been occurring.  In other words, from an infinity of time in the past, the Mormon plan of exaltation (becoming gods) has been in effect.  The only problem is that this is logically impossible.  Since it is logically impossible, this means that Mormonism is false.  Let's look closer.

There cannot be an infinite regression of causes, i.e., a god that exalted someone to godhood, who exalted someone to godhood, ad infinitum.  This is logically impossible.  Why?  Because you cannot cross an infinity.

In other words, in order for us to get to the present state of this god on this planet, there would have had to be an infinite number of exaltations in the past.  But, this cannot be because, in order to get to the present, you would have to transverse an infinite number of exaltations.  But that is impossible since you cannot transverse an infinity--if you could cross (transverse) an infinity of time, then it isn't infinite.  Therefore, the Mormon system of infinite regressions of exaltations to godhood is impossible, and Mormonism is proven false.  Simple.

Another way of looking at this is to ask what is the first cause of exaltation to godhood?  To be exalted means someone (a god) would have to perform the action of exaltation (as Mormonism teaches).  But, if there is an infinite number of exaltations (an infinite number of causes of exaltation), then we could never find the first cause because there wouldn't be one.  If there is no first cause, then there can be no second, no third, etc., and there could never be a sequence of these events to occur.

However, Mormons will not give in to a logical proof since their testimonies are not based on facts but on what they claim is a testimony of the Holy Spirit.  Of course, all cult groups have testimonies that their church is true (proving that testimonies are contradictory and untrustworthy as a means to determining truth).  Nevertheless, they are taught to "feel" theological truth--not think it through.
How then do they respond to this logical proof that Mormonism is false?  Normally they say that it is a mystery. Mysteries are fine, but they cannot suffice as an explanation if they contradict logic. In other words, if a principle is blatantly illogically, it cannot be true. Did you get that? It cannot be true. Saying it is a mystery means nothing if the proclamation of that mystery violates the laws of logic.  Mormonism is proven false.

What is the truth?

Okay, so if the Mormon principle of eternal regression of exaltations is logically impossible, then what is the truth?

The truth is that there is a single uncaused cause.  Logic necessitates that there must be a single being who is without beginning and upon which time has no meaning or affect who is the single uncaused cause.  The Bible says that God is unchanging (unlike the Mormon god) and that he has been God from eternity.  This is exactly what logic necessitates as being true.  The God of Christianity is not an exalted man from another planet with a goddess wife.  The God of Christianity has always been God and has never been anything else.

Check out the following verses.

  • "For I, the LORD, do not change; therefore you, O sons of Jacob, are not consumed." (Mal. 3:6).
  • "Before the mountains were born or You gave birth to the earth and the world, Even from everlasting to everlasting, You are God." (Psalm 90:2).

What is sad is that this simple logical proof, and it is a proof that Mormonism is false, will mean basically nothing to those whose spiritual eyes have been blinded by the god of this world.

  • "And even if our gospel is veiled, it is veiled to those who are perishing, 4 in whose case the god of this world has blinded the minds of the unbelieving so that they might not see the light of the gospel of the glory of Christ, who is the image of God . . . " (2 Cor. 4:3-4).
