St Ignatius of Loyola was extremely important in developing phenomenological prayer. By phenomenological prayer I mean prayer which explicitly relies on the senses, a sort of contemplative (sometimes referred to as "Ignatian") prayer where ones utilises the senses and imagination to pray. One way of doing this is to insert oneself in a passage from the Scriptures: for instance, one can take a passage close to me personally, that of Peter asking Jesus to bid him come and walk on water, and place oneself within the boat. What are the smells, the sounds? Does the air have that slightly salty taste, on that sea? What does it feel like to be there? What can you see? How does Peter feel? All these questions are questions about experience, about the phenomenological quality of the events that are happening. This distinctively Ignatian style of prayer is, obviously, at the heart of Jesuit spirituality, and as such, close to my own.
Even more than just a distinctive brand of spirituality, phenomenology is key to understanding the Bible. You cannot, and I mean it, you cannot understand the Gospel accounts, or even many of the more human-interaction based books of the Old Testament, without at least some understanding of phenomenology. One does not, of course, need to know fancy long words like "phenomenology" - in some sense, phenomenology is the only branch of philosophy we do from birth, since all newborns seem to do is process sense data and react to such stimuli. It is crucial to understanding the Gospel accounts because human interactions are crucial to them. I think Bonhoeffer is right, for instance, in arguing that the immediate response of the disciples to Jesus' call to follow him cannot be explained in terms of some quick calculation of self-interest or a prior relationship with Jesus. It must be understood that the call of Jesus carries with it a phenomenal quality which is completely unlike an encounter with any other human person.
This phenomenal quality of encountering Jesus, particularly his call, but also his conversations, must be understood the understand Jesus, and the responses people have to Jesus. If only for that reason, phenomenology is an area worth considering, and for precisely that, I will dedicate some non-negligible thought and writing to discussing that issue.
