4 Informal Logical Fallacies and Biblical Examples

by Billy Dyer

Is logic foreign to the New Testament? Is it a field of study we should reserve for the philosophers and let the theologians be by themselves? Of course not! Logic is logic and works in every field of reality. If God is the God of Truth then we should expect to see Him, the inventor of logic, using logic. Humans didn’t invent logic, we simply use it, name it, and study it. Today I want to look at a few examples of Informal Logical Fallacies and how the Bible actually uses these principles correctly.

The Law of Non-Contradiction

  • It states, “Two contradictory statements cannot possibly be true at the same time and in the same relationship.”
  • For example you couldn’t say, “The Earth is round and not round.”
  • This law is fundamental to thinking. You cannot have a conversation without it. We all use it intuitively. If someone denies this law then you can point out they are actually using it right now. What do I mean? If I were to say, “There is a Law of Non-Contradiction” and someone said, “No there is not” then they would be contradicting me to say there is none!!!
  • 1st John 2:4 says, The one who says, “I have come to know Him,” and does not keep His commandments, is a liar, and the truth is not in him” John states it is a contradiction to profess to know Christ and yet not obey him. You cannot do both at the same time.

Hasty Generalization

  • This law points out the fallacy when we jump to a conclusion without sufficient data. We extrapolate from a small sample to create a general rule. 
  • People/Organizations formulate rules or policies from accidental or exceptional situations. 
  • For example…When the youth group has an overnighter and someone breaks a window. The Church will then make a rule that we can never have another overnighter because they are destructive to the Church building.
  • Biblical Example…Someone reads a story of God destroying Sodom/Gomorrah and concludes He is a wrathful and mean God. They did not collect enough data to balance God’s characteristics…
