We put that question to a group of architecture students at the Catholic University of America in Washington. The big transformations in spiritual belief are being led by millennials, people just like our students.We asked them to reflect upon their own experiences with organized religion, their own beliefs and the “search” for a new kind of church they might be engaged in. We shared demographic info about how religion is changing in America. We then picked a site in Washington for which the students could design a new kind of house of worship.
