Hans Urs von Balthasar was one of the most preeminent XXth century catholic theologians, and this is, in my opinion, his most important work - by this I mean the whole trilogy (Glory, Theodrammatica, Theologica). This first volume of Glory, Seeing the Form (Schau der Gestalt) seems to be really fundamental for a serious understanding of the guidelines of his thought.
At the fantastic Introduction, after a superb hymn to the Beauty, he presents us with an accurate analysis of the elimination of this universal (Beauty) from both Catholic and Protestant theology, besides a review on the possibilities of a Protestant Aesthetics. He tries, then, to make it clear the difference between an Aesthetic Theology from a Theological Aesthetics. The task and structure of the latter is then explored.
There's no way to go on in such detailness through the whole book, because there are too many points to look at, and this is not the place to do it. But it's worth to say that the main objective of the author, as he goes on working on the 'subjective evidence' through the 'light' and 'experience' of faith (the second part of the book), and at the third part, the 'objective evidence', the main objective, as I was saying, is to precise a 'form', to state the main difference of Christianity from all other world religions, which is exactly the visible and historical form of the God made flesh. After 'seeing' the form of revelation which came from the Old Covenant, we have in Christ the centre of its form, that is, the centre of God's revelation form.
I strongly recommend this book to everyone who is seriously wanting to deep his theological studies, or to anyone who wants to learn more about the actual situation of the Church, and Christianity as a whole.
