Terry Mattingly has created a good compilation of bits from the mainstream media obituaries:
Later, readers learn that Solzhenitsyn actually regained his Orthodox faith in the crucible of pain — the labor camp. Of course, the writer also struggled with his own sins and faults, perhaps best symbolized by the affair that ended his first marriage, which he justified as a consequence of his fierce pursuit of his art. This leads to a question that none of the obituaries answer (at least none of the stories that I have seen): What was his relationship to Orthodox Christianity in his adult years? While he lived in the United States? Upon his return to the deeply flawed Mother Russia that he loved so deeply?
