Thanks for your blog! The quotes look interesting, I've added the "The Idea of The Holy" to my reading list.

Such immensity inspires awe, but it is also dangerous, which we usually see as a bad thing.

Awe inspiring sure, but dangerous? What is an example of a danger are you thinking of?

For the faculty of noticing and experiencing the numinous, Otto uses the term "divination" (which, as student of occult practice, is somewhat confusing to me - where are the cards or lots or flights of birds?)

That's curious, it seems that Otto defines divination differently from the generally accepted "predicting the future using omens or the supernatural". Certainly you can worship without trying to predict the future.
