This work explores the Christian faith in the current intercultural context of Arab societies. It argues that Arab Christianity seeks to express the Christian faith through openness to Muslim otherness, existential conviviality, and fraternal solidarity. In order to safeguard not only the physical existence of these communities but also and above all the relevance and richness of their message of life, the theological reflection presented here takes on a three-part task. First, it faithfully describes the sociopolitical and sociocultural reality of the historical integration of Arab Christian communities. Second, it reinterprets the content of the Christ event with reference to the challenge of Muslim otherness. And finally, it offers a path for conversion that involves a form not only of evangelical practice, designed to foster bonds of fraternal solidarity between the inhabitants of the Arab world but also of shared spiritual quest for moral and political commitment.
