Meeting with you now, in front of one of the newest and most beautiful buildings in Washington, it is fitting that we re-dedicate ourselves to the peaceful progress of all men under God.
And I should like to assure you, my Islamic friends, that under the American Constitution, under American tradition, and in American hearts, this Center, this place of worship, is just as welcome as could be a similar edifice of any other religion. Indeed, America would fight with her whole strength for your right to have here your own church and worship according to your own conscience.
The concept is indeed part of America, and without that concept we would be something else than what we are.
— President Dwight D. Eisenhower, speech at the opening of the Islamic Center Mosque, Washington, D.C., June 28, 1957.
