I come to this magnificent house of worship tonight because my conscience leaves me no other choice. I join you in this meeting because I am in deepest agreement with the aims and work of the organization which has brought us together: Clergy and Laymen Concerned about Vietnam. The recent statements of your executive committee are the sentiments of my own heart, and I found myself in full accord when I read its opening lines: \A time comes when silence is betrayal.\ And that time has come for us in relation to Vietnam

This is the 37th time I have spoken to you f rom this office, where so many decisions have been made that shape the history of this nation.

Tonight I want to discuss the importance of the television news medium to the American people. No nation depends more on the intelligent judgment of its citizens. No medium has a more profound influence over public
