Bonhoeffers ecclesiology .PP Every day I check my electronic mail for a commentary on Bonhoeffer's work, but of late I have been disappointed, and I ask again whether our apparent inability to speak to one another reflects the fact that we are a very disparate group. .PP For the past month or so I have been reading and meditating on Bonhoeffer's Sanctorum Communio. I have several explanantions for my particular interest in Bonhoeffer's ecclesiology. Most important is my perplexity at my own relationship to the church; just as important to me is my belief that just as theology is an indispensable prerequisite for understanding the human spirit and soul, i.e. for psychology, so ecclesiology as the theory of sacred community is the foundation of understanding secular community; anf the individual's making for himself a home in the secular world, oikeiosis, is quite analogous to his finding his home in the sacred community. I found Bonhoeffer's doctoral thesis stimulating and suggestive; but it did not provide me with the answers that I sought, and it left me, in the end, only with an even greater perplexity. .PP Bonhoeffer's exposition, as has been stated here before, eschews empirical and historical considerations. It relies on scholastic inferences and on what Bonhoeffer calls "Offenbarung", revelation .PP Bonhoeffer's statement, to the effect that it might be efficacious to rely on the study of the church as a point of beginning (for the study of religion) as opposed to beginning with the study of deity strikes me as being significant both of the seriousness of his purpose and of the difficulty of his enterprise. .PP For it seems to me much easier to speculate and theorize about an invisible deity, than to come to terms with the church as the manifestation of the divine in history. .PP Bonhoeffer's concern with ecclesiology reflects his emphasis on the concreteness and actuality of the Christian experience; and this in contradistinction to apparently self-sufficient schemes of the idealist and the mystic, who are preoccupied with the inventions of their own minds. .PP Bonhoeffer's concern with ecclesiology does not, however imply that we should find in his works an algorithmic exposition of what the church is and means. It would be unrealistic and naive to expect such a solution; the only compelling conclusion is a negative one, namely that the incarnation of the divine which the church constitutes remains for us conceptually (intellectually) a dilemma, and practically, an impossibility. .PP I hope it is not presumptuous of me to observe that Bonhoeffer wrestled with this dilemma not entirely was only partially successful, he received the highest grade, his family was surely proud of him, a remarkable grasp of the sociologic and philosophical literature of his day. .PP But the insufficiencies are all too apparent. "Revelation as the source of certainty is problematic. I do not find answers to "my" questions...
