The open letter "A Common Word Between Us and You" (EEC) is a unique example of international Christian-Muslim dialogue. The core message of EGW is that peace between Christians and Muslims is crucial for the future of the world. EGW wants to achieve political change by means of theological reasoning, because peaceful Islam-West relations can be achieved by improving Christian-Muslim relations. This study examines - as the first of its kind - the origins and impact of EGW and highlights the importance of specific historical and socio-political contexts and circumstances that have had a significant impact on its form and content.
