I am studying what Karl Rahner calls "transcendental experience." I have read biographical info on Rahner and the factbook entry. Karl Rahner, Foundations of Christian Faith: An Introduction to the Idea of Christianity (New York: Crossroad, 1985), is helpful in the Introduction and Chapters I and II. On p. 20 Rahner describes transcendental experience as "the subjective, unthematic, necessary and unfailing consciousness of the knowing subject that is co-present in every spiritual act of knowledge, and the subject's openness to the unlimited expanse of all possible reality." I do not see where this concept comes from in theological references. Rahner's transcendental theological thought is based on the idea that human openness to transcendence stems from a pre-existing understanding of infinite reality or the transcendent God. Rahner's fundamental position on God is that He is the "absolute" or "holy" mystery. As an utter mystery, God is unfathomable and impenetrable. However, human beings can know and relate to God as God, who has generated and created non-divine entities. How can I use Logos to study this from a biblical and evangelical perspective?
