In the 1950s, he writes, â??Catholics inhabited a parallel culture that, by virtue of their numbers, ethnic diversity, wide geographical distribution, and complex of institutions mirrored the outside â??publicâ?? culture yet was manifestly different.â? As Mr. Woodward sees it, Catholics were surrounded by a membrane that intermediated between the worlds of American society and the church. The â??powerful sense of communityâ? nurtured within this membrane has virtually disappeared. Now Americans â??journey toward adulthoodâ? not through relationships formed by families, neighbors, teachers, pastors and community organizations but through the effort of discovering â??an inwardly derived, original, and authentic self,â? one autonomous from â??institutionally structured relationships.â?
