On May 18, 1997, a new stage of relations between Christians and Muslims began. Chiara Lubich, a Christian woman, was invited by Imam W. D. Mohammed, a charismatic leader of African American Muslims, to address the faithful gathered in the Malcolm X Mosque in Harlem. At the end of that day, the Imam said: “Today here in Harlem, New York, a page of history has been written.” The two leaders made a pact of fraternity that was then extended to the two movements. Since then, regular meetings have been held in the United States between Christian and Muslim communities, black and white, which aim to build universal brotherhood with an impact on cities and neighbourhoods. More than forty mosques and Focolare communities are involved in various cities.
