(CHICAGO) — Cardinal Francis George, a vigorous defender of Roman Catholic orthodoxy who played a key role in the church’s response to the clergy sex abuse scandal, has died. He was 78. The Chicago archdiocese says George died Friday after a long fight with cancer. Appointed to lead the archdiocese in 1997, George became a leading figure of his era in the American church. He oversaw the contentious new English-language translation of the Roman Missal, one of the biggest changes in Catholic worship in generations.
