Paul Tillich
This chapter examines how critical insights about the nature of sin, finite freedom, and a critique of progress in the works of Reinhold Niebuhr and Paul Tillich reveal deep resonances between their respective characterizations of the human condition. This resonance stems from their common reliance on Søren Kierkegaard’s account of anxiety. However, there are slight but significant differences in Niebuhr’s and Tillich’s respective use of this account of anxiety as well. This is especially evident when one considers their account of a related theological concern: the capacity for human self-transcendence. Accounting for these differences in their view on human self-transcendence illustrates how and why more pronounced differences exist in their respective accounts of the relationship of love and justice tempered by hope, as found in Christian Realism (for Niebuhr) and the fulfilment of time as kairos in Faithful Realism (for Tillich).
