Mother Teresa as a psalm

(RNS) On September 5, 1997, the world mourned when Mother Teresa, whose work with the poorest of the poor made her a global icon, died of a heart ailment at age 87. Five years later, the world did a double take, when a volume of Teresa's private letters revealed that the tireless, smiling nun spent the last 39 years of her life in internal agony.
