Death and Legacy
After several years of deteriorating health in which she suffered from heart, lung and kidney problems, Mother Teresa died on September 5, 1997 at the age of 87. Since her death, Mother Teresa has remained in the public spotlight. In particular, the publication of her private correspondence in 2003 caused a wholesale re-evaluation of her life by revealing the crisis of faith she suffered for most of the last 50 years of her life. In one despairing letter to a confidant, she wrote, Where is my Faith even deep down right in there is nothing, but emptiness & darkness My God how painful is this unknown pain I have no Faith I dare not utter the words & thoughts that crowd in my heart & make me suffer untold agony. While such revelations are shocking considering her public image of perfect faith, they have also made Mother Teresa a more relatable and human figure to all those who experience doubt in their beliefs. For her unwavering commitment to aiding those most in need, Mother Teresa stands out as one of the greatest humanitarians of the 20th century. She combined profound empathy and a fervent commitment to her cause with incredible organizational and managerial skills that allowed her to develop a vast and effective international organization of missionaries to help impoverished citizens all across the globe.
However, despite the enormous scale of her charitable activities and the millions of lives she touched, to her dying day she held only the most humble conception of her own achievements. Summing up her life in characteristically self-effacing fashion, Mother Teresa said, By blood, I am Albanian. By citizenship, an Indian. By faith, I am a Catholic nun. As to my calling, I belong to the world. As to my heart, I belong entirely to the Heart of Jesus.
