We MUST live by the law of non-contradiction

Is it possible to live life with this kind of logic: Yes, the garden has weeds in it; no, the garden has no weeds in it! I’m talking about the same garden at the same time and in the same sense. If I were to reason like that, you’d have good reason to consider that I need a psychiatric assessment.

However, many people don’t understand that this is dealing with a fundamental law of logic, the law of non-contradiction. Some call it the law of contradiction or the principle of non-contradiction. No matter what one names it, it is a fundamental to dealing with contradictory statements.

A.  Christians and contradictions

I explained in an online forum that I was ‘in the midst of preparing a Christian education curriculum for Grade 7 & 8, with some easy entry info on the nature of truth and the law of non-contradiction before I launch into details on the existence of God for 13-15 year olds’.[1]

A person responded, ‘That sounds rather dogmatic, and some of the touchy-feely posters may take exception to that’.[2]

My reply was[3] that ‘touchy-feely posters’ depend on the validity of the law of non-contradiction to live their lives. It extends to all in society, not just the existentialists. Let me explain:
Regarding the law of non-contradiction, let’s check something out from Scripture:

  • ‘God is not man, that he should lie, or a son of man, that he should change his mind. Has he said, and will he not do it? Or has he spoken, and will he not fulfill it?’ (Num 23:19 ESV).
  • ‘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’ (Heb 6:18 ESV).

So, God cannot lie.

The law of non-contradiction is a fundamental of all logic, whether in Christian or non-Christian circles.

B.  The law of non-contradiction explained

#  Bill Pratt has stated the law of non-contradiction in this way:

What is the law of non-contradiction? There are at least three ways to state it:

1. A thing cannot both be A and not-A at the same time and in the same sense.

2. A thing cannot both exist and not exist at the same time and in the same sense.

3. A statement cannot both be true and not true at the same time and in the same sense.[4]

Bill Pratt explained further:

It is impossible to deny this law without invoking it in your denial, yet time and again I have heard people try do just that!

Why would I spend a blog post writing about this?  Because a person who thinks that this law is not true will become a thoroughly confused individual whose thought life is a complete mess, full of contradictions and inconsistencies.  I have met a few of these people, and they both sadden and scare me.

All of our beliefs, thoughts, and knowledge are built on top of the law of non-contradiction, so when a person tries to deny this foundation, they are bound to go way off track in their pursuit of understanding reality as it really is.

If you have any doubts about this fundamental law of rationality, try and deny it, but then write out your denial in a sentence – “The law of non-contradiction is false” – and ask whether your statement is both true and false at the same time and in the same sense.[5]

C.  God and the law of non-contradiction

Logic Bomb by utrescuFrom a biblical perspective, we cannot say that Jesus is the only way to eternal life (John 14:6 ESV) and that Jesus is one of many ways to eternal life. That statement violates the law of non-contradiction and makes God a liar. In this day of postmodern multicultural values, it is all the more important to maintain biblical integrity with the law of non-contradiction.

It’s fundamental to life. I’m expecting a fellow to deliver to my front door this morning a cartridge refill for my HP laser printer. He said: I will deliver your cartridge on Friday morning. With that statement, he did not mean, I will deliver the cartridge on Saturday or Sunday morning. That would be a lie.

In defending biblical truth, we have to stick with this fundamental of logic: God does not lie and what he says in Scripture he means. Of course we need to understand the difference between the Old Covenant and the New Covenant in interpretation. If the law of non-contradiction does not hold up, we are doomed as a society. Why? There will no longer be truth promoted and lived in the marketplace.

The law of non-contradiction says that something cannot be A and non-A at the same time and in the same relationship.

D.  A Christian example of violation of the law of non-contradiction

#  I have read Christians who accept contradictory interpretations of Scripture and others who ‘hear’ from God with a message that violates Scripture. Here is one with which I contended with as I was writing this article.

On another forum I encountered a person who stated, ‘The Holy spirit created The Lord of Hosts, from sperm taken from The Lord God Almighty. The Holy Spirit later implanted The Lord of Hosts in Mary, as an embryo/fetus’.[6] He told us:

Have ANY of them experienced Numbers 12:6, as I have? I prayed for wisdom, knowledge, understanding and experience, for about 10 years, daily (sometimes several times per day), before He answered me. He took me through the Bible, giving me an understanding of how He feels. I spent nine years in research on the internet, prayer, visiting churches, communicating with many ministers, and so on, after receiving the vision and dream ‘in riddles’. Missing scriptures appeared while I was reading the NT scriptures, on several occasions, and after reading them, they disappeared again. None changed the basic ‘story’ of The Son of Man. They were informative, in nature.[7]

I told him that this is fantasy – his fantasy. There is not a scrap of biblical evidence to support this statement. Has he come onto this forum to plant and grow this kind of false religion?[8] In fact, the biblical evidence is:

Now the birth of Jesus Christ took place in this way. When his mother Mary had been betrothed to Joseph, before they came together she was found to be with child from the Holy Spirit. 19 And her husband Joseph, being a just man and unwilling to put her to shame, resolved to divorce her quietly. 20 But as he considered these things, behold, an angel of the Lord appeared to him in a dream, saying, “Joseph, son of David, do not fear to take Mary as your wife, for that which is conceived in her is from the Holy Spirit. 21 She will bear a son, and you shall call his name Jesus, for he will save his people from their sins.” 22 All this took place to fulfil what the Lord had spoken by the prophet:

23 “Behold, the virgin shall conceive and bear a son,
    and they shall call his name Immanuel”

(which means, God with us). 24 When Joseph woke from sleep, he did as the angel of the Lord commanded him: he took his wife, 25 but knew her not until she had given birth to a son. And he called his name Jesus (Matt 1:18-25 ESV).

This fellow had violated a fundamental of life and of Scripture. Contradictory messages cannot both be true. He breached the law of non-contradiction. He contradicted Scripture.

His contradictions (violations of the law of non-contradiction) continued in a repetitive fashion:

No, this is NOT fantasy. I asked God for this understanding, and He gave it to me. Have you ever asked God for a true understanding of the scriptures? Start with the scriptures, and then ask God for a true understanding of them. Forget what the ‘blind’ ministers have taught you. They rely on college or university degrees/diplomas, and man’s ‘ordination’.

When you read the historical generations pertaining to the Israelites, in the Book of Genesis, you will find the term ‘BEGAT’ being used. This is one of the tenses of the verb ‘begit/beget’ (sic). The Lord of Hosts was ‘begotten’ of/from God. In all cases, male sperm is used. In the case of The Lord of Hosts, no female was involved, thus, an exact duplicate, is created. In the case of The Son of Man, The Lord of Hosts ‘WAS IN’ the Christ Child [‘God with us’]. The body of Mary did NOT change the physical appearance of Christ. God showed me, that there is only ONE ANSWER to how this could happen. The Holy Ghost implanted The Lord of Hosts in Mary, as a human embryo/fetus, that contained The Lord of Hosts. Remember, man is created in the image of God. ‘The Lord of Hosts/Son of Man’ is in the ‘exact image’ of The Lord God Almighty.[9]

How should I reply? This was my understanding of what he was doing.[10]

His view that ‘I asked God for this understanding, and He gave it to me’ contradicts Scripture. It violates the law of non-contradiction. God cannot tell you that ‘The Holy spirit created The Lord of Hosts, from sperm taken from The Lord God Almighty. The Holy Spirit later implanted The Lord of Hosts in Mary, as an embryo/fetus’ and yet the Scriptures tell us that the Trinitarian Lord God – Father, Son and Holy Spirit – has always existed: ‘In the beginning God created the heavens and the earth’ (Gen 1:1 ESV). There was no such sperm from God that was used to create the embryo. No such information is given in Scripture. It is contrary to Scripture.

God does not contradict himself by telling you something about the Lord of Hosts who was created by sperm taken from the Lord God Almighty. The Lord God is spirit. He does not have the ability to have sperm within himself. ‘God is spirit, and those who worship him must worship in spirit and truth’ (John 4:24 ESV).

This fellow was hearing a voice that was giving him a message that is not from God. He is providing us with deceptive information in what he was posting here. It was false.

He continued his ‘God told me’ line: ‘I experienced Numbers 12:6 KJV Bible, before God began His teachings. Satan CANNOT duplicate Numbers 12:6’.[11] To this I replied that I have already shown you that you are listening to another voice that is not God’s. God cannot give contradictory messages.[12]

I’m asking: Is this fellow Christian or into hearing other voices (perhaps of the occult) that he thinks are Christian. I cannot imagine what it would be like to have this kind of anti-Christian theology in a church where he’s of the view that ‘this is what God told me when I experienced Numbers 12:6 KJV.

E.  Conclusion

# In all of our actions, whether by Christian or non-Christian, we cannot violate the law of non-contradiction without causing a massive upheaval in society, the church, and in online forums.

Could you imagine working for an organisation where you couldn’t depend on the honest words and actions of people?

We must live out the law of non-contradiction in our lives. This states that

something cannot be both A and non-A at the same time and in the same sense. Something cannot be both true and false at the same time and in the same circumstance.

That’s a fact of life.
