RT Article T1 Letzte Sorge, letzte Zuversicht JF International yearbook for Tillich research VO 13 IS 1 SP 133 OP 178 A1 Fritz, Martin LA German PB De Gruyter YR 2018 UL https://www.ixtheo.de/Record/1584995041 AB The bestseller The Courage to Be presents Tillich’s “concrete existential” notion of religion that is based on the key terms ‘anxiety’ and ‘courage’. This essay traces this idea’s long history in Tillichian thinking that reaches back to the mid-twenties lectures on dogmatics in Marburg and Dresden, and outlines its core elements, pointing out its contrast to Tillich’s earlier notion of religion as the mind’s intention on absolute meaning. Subsequently, the discussion moves to Tillich’s theorem of the double principle of ‘individualization and participation’, providing instructive insights into basic social presuppositions and types of religion, instructive especially in the present-day situation of religious pluralism.
