Disclaimer: FOL is not the be-all and end-all. In fact, when it comes to the mystery of the Godhead, FOL is rather useless.

When it comes to formal deductions, FOL is a strong proof of claims. Its components are

  1. Propositional calculus, click an example
  2. Existential quantifier, for some (1 Corinthians 9:22)
  3. Universal quantifier, for all
  4. Transitivity: x=y, y=z => x=z
  5. Proof by contradiction, click Jesus used it.
People not trained in FOL tend to overgeneralize and jump to conclusions. I was the same.
