Abstract
Besides dialogue with the Jews, Christians were most involved in the dialogue with Muslims. This dialogue was accentuated and became visible especially in modern and contemporary times, with the increase in violence, which had often religious justifications on the part of those involved. The dialogue between Christians and Muslims took a new direction after the attacks of September 11, 2001, in New York and after those that followed in Europe and all over the world. It was discussed in those days and immediately after about the validation of the well know theory of clashes of civilizations, formulated by Samuel Huntington, in his book written in 1996. Starting from these events, within the dialogue between representatives of Christianity and of Islam, there were many other intensive moments that had to be resolved through a profound theological analysis and with understanding and respect from the followers of the two monotheistic religions.
