Read the following excerpt from Senator Edward M. “Ted” Kennedy’s Faith, Truth and Tolerance in America, 1983. "I have come here to discuss my beliefs about faith and country, tolerance and truth in America. I know we begin with certain disagreements; and I strongly suspect that at the end of the evening some of our disagreements will remain. But I also hope that tonight and in the months and years ahead, we will always respect the right of others to differ, that we will never lose sight of our own fallibility, and that we will view ourselves with a sense of perspective and a sense of humor. After all, in the New Testament, even the Disciples had to be taught to look first to the beam in their own eyes, and only then to the mote in their neighbor’s eyes."
