Don Thorsen and Keith H. Reeves in their book, What Christians Believe About the Bible (2012):
1) Dictation (or Mechanical) Theory - God dictated exact words for certain people to write.
2) Verbal, Plenary Theory - God inspired the words which each writer chose to use.
3) Dynamic Theory - A dynamic is involved between the Holy Spirit and the writers; the bible is God's Ideas using human abilities.
4) Concursive Theory - Like the Dynamic Theory, but maintains that the dynamic is a mystery which can't be fully explained.
5) Sacramental Theory - Generally, God uses physical things and people to signify His meanings to and through His people.
6) Partial, Limited or Degrees Theory - Some parts of the Bible may be directly influenced by God; other parts are people's attempts to represent what they have experienced or learned about God.
7) Dialectical Theory - The biblical authors write under the influence of God in and through the experience of their lives.
8) Humanized Theory - Just as it sounds: humans write what they think God is and thinks.
9) Existential, Critical Theory - We find the Bible in this world, such as it is from the past, with its claims of divine influence; and we have to wrestle with these claims as best as we can, and we do so now, in THIS current life and time.
