More about his theology: Harnack was a German Lutheran theologian. In 1900 he published a series of lectures into a book titled Das Wesen des Christentums (What is Christianity). This was a very important book at the time and still is for contemporary theological studies. In it he reduced Christianity to:
- God is Father caring for his children whereby things will go well and all are provided for.
- The idea of providence, there is a rule governing history whereby things will always work out for the good.
- The human is race is God’s children in relation to God the Father who takes care of them.
- The universality of these three truths as all of us bear the face of the human family God thus sets forth what we need because we are in the face of our foolishness in order that we would be free.
