Introduction: The Cosmological Argument

by Dean Meadows

Apologetics, or defending the faith, is something every Christian should be involved in (1 Pet. 3:15). The foundation of popular apologetics is what I like to refer to as the “Big Three” apologetic arguments. I will be writing a brief introduction to three: the cosmological, teleological, and moral. For starters, here’s the cosmological argument.

Definitions And History

The cosmological argument is so called because it is an argument (logos) for the existence of God by observing the universe (cosmos). The cosmological argument is often credited to Aristotle, and later Thomas Aquinas. The concept is seen (though not very developed) in Hebrews 3:4.

The cosmological argument is closely related to the concept of cause and effect. In short, the cosmological argument can be outlined as follows:

  1. Every effect must have an adequate or simultaneous cause (the law of causality).
  2. The universe is an effect which demands an adequate or simultaneous cause.
  3. God (understood as a transcendent creator) is this adequate cause.

In this way, the cosmological argument works from the observable universe backwards. The question which the cosmological argument seeks to answer is, “what caused the massive effect of what we see as the universe?” The answer can logically be shown to be a supernatural first cause. The cause is supernatural in that it exists outside of the physical universe. How could something inside of the physical universe create the physical universe?…
