Any attempt to identify the "theology" of Concluding Unscientific Postscript is confronted from the outset by several difficulties. The notion of Christianity as an existence-task leads Johannes Climacus to state that Christianity is not a doctrine, but an existence-communication. This notion of Christianity as an existence-communication forms the basis of Climacus' critique of contemporary theology. In order to assist the subjective thinker in thinking about his existence and existing in his thinking, a new type of dialectic is needed, namely what Climacus calls "the Greek or the existence-dialectic", "concrete dialectics", or, more frequently, "qualitative dialectics". Qualitative dialectics is concerned with the problem of identifying the absolute telos and ensures that the human being sustains a relationship to the absolute telos in existence. Climacus describes the absolute orientation of the individual to the absolute telos by renunciation, suffering, and guilt-consciousness as "the religion of immediacy" or "religiousness A".
