Somehow I managed to get a theological education and practice several decades of parish ministry without encountering the idea of spirituality. In fact, I don’t recall even hearing the word until about ten years ago.
I did read Rudolph Otto’s The Idea of the Holy, an introduction to a new and strange world of mystery and transcendence, which I did not entirely trust as authentic. Mircea Eliade’s The Sacred and the Profane forced me to think outside the boundaries of my own theological family. But I was never very comfortable with this material and retreated as quickly as I could to the safety of Pauline, northern European, university-refined intellectualism. I was better at thinking about Otto’s numen than at experiencing it.
