In recent days there are many theological suggestions that through the aesthetical experiences a way to seek the possibility of the knowledge of God can be attempted. These kind of aesthetical theology or theological Aesthetics has two assumptions that at first, the so-called analogia entis tradition is regarded as the right interpretation of the revelation of God, and at second, we are surrounded by the structure of beings the if we meet the unsayable God, then it means that we must realize that we are confronted with the structure of beings that we have nothing but to say this unsayableness. That means we are surrounded by the grace of unsayableness. So the question arise: can this fundamental aestheic experience express the christian view of God? This question leads us to the theology of Karl Barth. We believe that the aesthetical experience can be rightly appreciated when we follows the theological understanding of Karl Barth about this matters.
