Remarks at Ceremonies Opening the Islamic CenterWhen it comes to where we are as a nation today, Democrats are bad but Republicans are not blameless... by any means.
June 28, 1957
Mr. Ambassador, Dr. Bisar, Governors of the Islamic Center, and distinguished guests:
It is a privilege to take part in this ceremony of dedication.
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 one 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.
This concept is indeed a part of America, and without that concept we would be something else than what we are.
The countries which have sponsored and built this Islamic Center have for centuries contributed to the building of civilization. With their traditions of learning and rich culture, the countries of Islam have added much to the advancement of mankind. Inspired by a sense of brotherhood, common to our inner most beliefs, we can here together reaffirm our determination to secure the foundation of a just and lasting peace.
Our country has long enjoyed a strong bond of friendship with the Islamic nations and, like all healthy relationships, this relationship must be mutually beneficial.
Civilization owes to the Islamic world some of its most important tools and achievements. From fundamental discoveries in medicine to the highest planes of astronomy, the Muslim genius has added much to the culture of all peoples. That genius has been a wellspring of science, commerce and the arts, and has provided for all of us many lessons in courage and in hospitality.
This fruitful relationship between peoples, going far back into history, becomes more important each year. Today, thousands of Americans, both private individuals and governmental officials, live and work-and grow in understanding-among the peoples of Islam.
At the same time, in our country, many from the Muslim lands-students, businessmen and representatives of states-are enjoying the benefits of experience among the people of this country. From these many personal contacts, here and abroad, I firmly believe that there will be a broader understanding and a deeper respect for the worth of all men; and a stronger resolution to work together for the good of mankind.
As I stand beneath these graceful arches, surrounded on every side by friends from far and near, I am convinced that our common goals are both right and promising. Faithful to the demands of justice and of brotherhood, each working according to the lights of his own conscience, our world must advance along the paths of peace.
Guided by this hope, I consider it a great personal and official honor to open the Islamic Center, and I offer my congratulations to its sponsors and my best wishes to all who enter into its use.
Thank you very much.
