"You therefore must be perfect as your heavenly Father is perfect." -Jesus (Matthew 5:48 ESV)
The God of Christianity is a flawless Being of perfect righteousness. If there is one unholy speck in His countenance, or one fallibility, He does not qualify as God.
This is unfortunate for Latter-day Saints, as their God has seven weaknesses that disqualify him from being deity. The seven failings of the Mormon god are as follows:
1. He can Fall from Godhood
Mormon 9:19 in The Book of Mormon states that if God changes, he will cease to be God. Alma 42:13 goes on to explain that if God's justice is destroyed, He will stop being God.
From the LDS perspective, this is only logical. After all, God was a man who earned his Godhood, and any position you earn can be taken away.
When you take a possibility and spread it through eternity, it becomes a certainty. In other words, it isn't a question of whether the Mormon god will fall, but when.
This is not something a true believer needs to worry about. The God of Christianity has always existed as God. He is not under the authority of a "Grandfather God" or a universal law that can demote Him. Because He is secure in His position, we are secure in his promises.
Based on a few of the weaknesses I'll be describing, the god of Mormonism has fallen from his exaltation already.
2. He Sent an Unworthy Sacrifice for Sin
I expect Latter-day Saints to take offense at this charge. After all, Jesus lived a perfect life as an unblemished lamb, right?
However, in Mormon theology, Jesus didn't just atone for our sins, he came to earn his own exaltation. They are quick to point out that Jesus never referred to himself as perfect, or complete, until after his resurrection.
The implications are staggering. A being who was working out his own salvation was not qualified to work out ours. Do the math. A finite being cannot perform an infinite atonement.
Again, this isn't a problem for Christians because Jesus was complete before, during, and after mortality. If Mormonism were true, we might have expected Jesus to say, "I am finished" instead of "It is finished."
3. He's a God of Confusion
If there's one religion that should have all the answers, it's Mormonism. It has additional scripture besides the Bible and a prophet who receives direct revelation from God. If that's not enough, every member is capable of hearing from God.
It looks great on paper, but too many truth sources cause confusion. One might wonder why scripture, or a living prophet, are necessary at all if God talks to everyone.
The common LDS answer is a chain of command. Yes, we all receive revelation, but only fathers can get it for their families and only prophets get it for the church. But what happens when sources of truth contradict?
What if the Bible says God's word never passes away (Mark 13:31) but The Book of Mormon says many plain and precious truths were removed from scripture (1 Nephi 13:36)? What if the Book of Mormon says King David's polygamy was an abomination (Jacob 2:24), but the Doctrine and Covenants condones it (D&C 132:38-39)?
What if the living prophet received a revelation in 2015 that homosexuals were apostates and in 2019 he received another revelation that they weren't?
It almost feels like two opposing entities are fighting to control LDS doctrine. That, or maybe humans are so incapable of interpreting revelation, that no truth sources are reliable. Perhaps God simply changes his mind from time to time.
None of these options bode well for the LDS faith.
4. He's a Liar
Chapter 8 of the Gospel Principles manual has this to say about honesty:
When we speak untruths, we are guilty of lying. We can also intentionally deceive others by a gesture or a look, by silence, or by telling only part of the truth. Whenever we lead people in any way to believe something that is not true, we are not being honest.
The manual is absolutely right, and it condemns the god of Mormonism. According to the Pearl of Great Price, the Lord spoke to Abraham as he journeyed into Egypt.
Abraham 3:22-24 conveys the conversation:
22 And it came to pass when I was come near to enter into Egypt, the Lord said unto me: Behold, Sarai, thy wife, is a very fair woman to look upon;
23 Therefore it shall come to pass, when the Egyptians shall see her, they will say—She is his wife; and they will kill you, but they will save her alive; therefore see that ye do on this wise:
24 Let her say unto the Egyptians, she is thy sister, and thy soul shall live.
Technically, the statement was partially true. Sarai was Abraham's half-sister. But the Gospel Principles manual makes it clear that a half-truth is still a lie. The LDS scriptures portray God as purposely deceiving the Egyptians into thinking Sarai was not Abraham's wife.
This seems like an odd thing for the most powerful Being in the universe to do. Why not promise to protect Abraham instead? Typically, we resort to lying when we feel powerless. So maybe the god of Mormonism couldn't protect him.
This instance with Abraham pales in comparison to the Mormon god's Eden deception. In the garden, he told Adam not to eat the forbidden fruit lest he die. He left out the fact that he couldn't procreate without doing so, and that by obeying he would frustrate the whole plan of salvation.
Hebrews 6:18 (ESV) says: So that by two unchangeable things, in which it is impossible for God to lie, we who have fled for refuge might have strong encouragement to hold fast to the hope set before us.
If God can lie, we cannot trust His promises.
5. He's a Slave
In Matthew 12:29 Jesus asks, "How can someone enter a strong man’s house and plunder his goods, unless he first binds the strong man? Then indeed he may plunder his house." (ESV)
In context, Jesus is explaining that he casts out demons through the Spirit of God. The point being made is in order to subdue a strong man, a stronger man must bind him. Jesus is that stronger man.
Here's where things get dicey. In Doctrine and Covenants 82:10 we read:
I, the Lord, am bound when ye do what I say; but when ye do not what I say, ye have no promise.
In other words, we can bind God through our obedience, thus removing his ability to condemn us. Alma 11:37 explains that God can't save us in our sins.
So whether we are good or evil, we bind God and force him to save or condemn us. If men have the power to bind God, we must be His superior.
6. He Relies on Evil to Exist
2 Nephi chapter 2 explains that there must be opposition in all things. Verse 13 is of particular interest.
13 And if ye shall say there is no law, ye shall also say there is no sin. If ye shall say there is no sin, ye shall also say there is no righteousness. And if there be no righteousness there be no happiness. And if there be no righteousness nor happiness there be no punishment nor misery. And if these things are not there is no God. And if there is no God we are not, neither the earth; for there could have been no creation of things, neither to act nor to be acted upon; wherefore, all things must have vanished away.
To summarize, if there is no sin and misery, there is no God. This puts a whole new twist to the problem of evil where God creates evil because he needs it.
We can conclude that our sins enable God to exist. And since the existence of God outweighs whatever bad things we do, we're actually performing righteousness.
However, instead of thanking us, God punishes us for sinning. Maybe the LDS god is actually the evil one.
7. He is Unjust
Alma 42:13 says: Therefore, according to justice, the plan of redemption could not be brought about, only on conditions of repentance of men in this probationary state, yea, this preparatory state; for except it were for these conditions, mercy could not take effect except it should destroy the work of justice. Now the work of justice could not be destroyed; if so, God would cease to be God.
This verse states that if mercy extends beyond repentance in this life, it destroys justice. Despite this warning, Mormonism emphatically teaches that repentance can occur in the Spirit World.
This isn't the only way Mormon god fails the justice test. Doctrine and Covenants 132:26 says:
Verily, verily, I say unto you, if a man marry a wife according to my word, and they are sealed by the Holy Spirit of promise, according to mine appointment, and he or she shall commit any sin or transgression of the new and everlasting covenant whatever, and all manner of blasphemies, and if they commit no murder wherein they shed innocent blood, yet they shall come forth in the first resurrection, and enter into their exaltation; but they shall be destroyed in the flesh, and shall be delivered unto the buffetings of Satan unto the day of redemption, saith the Lord God.
This passage is referring to an ordinance called the second anointing where a Mormon's "calling and election" is made sure. In this condition, mercy completely overrides justice.
The anointed person can commit all kinds of sin. They can rape, steal, and deceive as much as they want, as long as they don't kill anyone.
A world where people can participate in human trafficking and still enter the Celestial Kingdom is a world where God's justice has been destroyed.
Only the Christian view makes sense of a God who justifies the ungodly (Romans 4:5). Our position is that Jesus was obedient on our behalf, and his righteousness is imputed to our account. Mormonism does not have the luxury of an imputation doctrine.
This leaves Mormonism's god in a rough spot. Not only is he an enslaved liar whose sustenance is wickedness, he's also unjust. He is simply not worthy of our worship.
Conclusion
Clearly, this is a much different god than the God of the Bible. Yet Latter-day Saints will point to spiritual experiences - such as their Mormon Testimony that’s rooted and grounded in the infamous “burning in the bosom” phenomenon as a kind of “trump card” for the above evidence that the Mormon god is a failed imposter and stay unmoved. And doing so they fail the test that God stated clearly He would use to prove them - to know whether they love the only true and living Lord God with all their heart and with all their soul:
If there arise among you a prophet, or a dreamer of dreams, and giveth thee a sign or a wonder,
And the sign or the wonder come to pass, whereof he spake unto thee, saying, Let us go after other gods, which thou hast not known, and let us serve them;
Thou shalt not hearken unto the words of that prophet, or that dreamer of dreams; for the Lord your God proveth you, to know whether ye love the Lord your God with all your heart and with all your soul.
Ye shall walk after the Lord your God, and fear him, and keep his commandments, and obey his voice, and ye shall serve him, and cleave unto him.
-- Deuteronomy 13:1-4 (KJV)
So Mormon friends, I’m here to warn you - which means that I must inform you, that if you are following this failed Mormon god, you too have failed. You have failed God’s test, you are following another god.
A false god. And it breaks my heart.
More than that, it breaks God's heart too.
