The Gospel Coalition has spelled out in their theological vision for ministry how they "intend to discharge Christian ministry and interact with our culture in biblical and theological faithfulness."
The document answers these 5 questions:
1. How should we respond to the cultural crisis of truth?
2. How should we read the Bible?
3. How should we relate to the culture around us?
4. In what ways is the gospel unique?
5. What is gospel-centered ministry?
The first 3 questions address the epistemological issue, the hermeneutical issue, and the contextualization issue, respectfully.
