This chapter discusses David Jasper’s notion of theological thinking, as this concept is briefly outlined inthe 1995 text “From Theology to Theological Thinking”. It does so by relating sketchily to an early personal encounter with David Jasper on the part of the author, when he faced Jasper with an idea of writing a dialectical post-Christian theology. Jasper was somewhat sceptical about the idea and suggested that theology should rather be post-Ecclesial. The author was rather perplexed by this comment at the time, but in due course realized that they each had very different emphases, despite a profound agreement on certain fundamental cultural issues. This chapter describes Jasper’s notion of theological thinking and puts it in contact with his later works, which may be seen as a kind of post-Ecclesial liturgical writing. This complex is put in relation to the author's own notion of post-Christian theology. The author aims for a more comprehensive critical theoretical perspective that may open up new horizons in radical theology.
