Over the weekend we posted Commonweal's 1945 response to the bombing of Hiroshima and Nagasaki. The cover story of our current issue focuses on another horror of the Second World War, the massacre of Polish military officers by Russian secret police at Katyn. In "The Ultimate Crime: Katyn & the Invention of Genocide," Historian John Connelly describes the long struggle for both Russians and Poles to come to terms with what happened at Katyn, and explains why "genocide" is such a complicated term.This issue also features a lengthy article by Mark S. Massa, SJ, "A Model Theologian: The Legacy of Avery Dulles." Massa examines Dulles's writings and achievements in theology and describes the cardinal's approach as one devoted to conversation and pluralism. He also explores some of the "radical effects" of Dulles's pluralistic approach.Not a subscriber? You can read Charles R.
