Lesson details

Key learning points

  1. There are two types of evil that exist in the world; moral evil and natural evil.
  2. Moral evil and natural evil raise questions about God's nature and existence; this is known as 'the problem of evil'.
  3. The inconsistent triad suggests that God does not possess the qualities of the God of classical theism.
  4. The inconsistent triad is used as an argument against God's nature and characteristics and/or God's existence.

Keywords

  • Evil - the opposite of good and a cause of suffering

  • Inconsistent triad - a representation of evil as being inconsistent with the nature of the God of classical theism

  • Omnibenevolent - the belief that God is all loving and infinitely good

  • Omnipotent - the belief that God is all powerful

Common misconception

The problem of evil only causes people to doubt God's existence.

The problem of evil also causes some people to doubt God's nature, rather than God's existence. The inconsistent triad challenges the belief that God is omnibenevolent and omnipotent.
