Problem
Discuss the key principles used to formulate theology. Then read through Ephesians 1:1-14 and thoroughly discuss each principle and how they relate to this specific passage.
This question comes from the book "Introduction to Biblical Interpretation" By Klein, Blomberg, & Hubbard, chapter 11, "Using the Bible Today"
The principles are Biblical Theology, Systematic Theology, Historical Theology, and Practical Theology. Explain where these principles is shown in Ephesians 1:1-14, and give a specific verse with the principles of Theology.
