I am always struck by the mammoth social changes that occur through the courage and commitment of one person. Rosa Park refused to sit in the back of the bus and was a catalyst in waking up the American conscience. Jeanne Mannford walked with a sign indicating her love for her gay son and opened up an avalanche of support by parents who were unsure how to react to their children.Sister Mary Scullion through her tireless efforts has enabled us to see the homeless as people deserving of our help and concern. Our power may pale compared to these enormous change agents but each of us has the power to change the world for the better
