Answer: C - comes from the Bible
Explanation: According to Luther, religious authority comes from the bible. This is so because Luther believes that the Bible is the primary place of Christian knowledge for who God is and what God does.
Therefore, Luther’s view of scriptural authority also requires examination of the principles Luther developed to help Christians understand and live out their faith in biblically grounded ways.
According to the doctrine of justification, often called the material principle of Lutheran theology declared that scripture is the final authority on all matters of faith which is the bible.
