The Academy for Jewish Religion California has rented space in several locations during its 21-year existence as a transdenominational seminary that trains rabbis and cantors. For a while it was housed in an office building in downtown Los Angeles, then at Hillel, the Jewish campus organization at the University of California Los Angeles. But beginning Oct. 1, in an arrangement both novel and pathbreaking, the academy will move to Loyola Marymount University, a private Catholic school founded by the Jesuit and Marymount orders.
