There is

  • Kerygma – Preaching the plain facts of the Gospel.
  • Didache – Preaching the implications and siginificance of the gospel.
  • Paraklesis – Urging on humanity the need to live out the implications of the Gospel Teaching.
  • Homilia – Treat an issue in the light of the Gospel message.
