Bio: The Croatian Jesuit Stjepan Tomislav Poglajen (1906-1990), better known in the world today under his code name Tomislav Kolaković, was suddenly torn out of historical oblivion by Rod Dreherʼs book Live Not By Lies: A Manual for Christian Dissidents (2020)...The later stages of his life—which he spent traveling the world in coordination with the Church leadership on tasks that are still unknown today—resemble a spy thriller, in part even realized in the book God’s Underground, which he published in 1949 [under the pseudonym "Fr. George"] with a preface by Fulton Sheen. Poglajen died in Paris in 1990, shortly after communism—whose demise he made a significant contribution to—finally collapsed.
