ABSTRACT
The Catholic Church acknowledges that Islam represents a major religion in France and thus makes the dialogue a test laboratory, not only for Christian-Muslim relations but also others, concerning the theology of religions practice. According to Muslims, Christians and Muslims worship the same God. The Catholic side suffers no lack of recent pronouncements affirming that this is also the view of the Church. This chapter summarises the theological foundations of interfaith dialogue between Christians and Muslims, namely, what is the relationship between the Spirit and the church, ecclesiology and pneumatology. The dialogue process has revealed two foundational perspectives. First, the Christian – Roman Catholic – approach to other religions is trinitarian. Second, the trinitarian faith is not something on which both Islam and Christianity agree. For Christians it is clear that the trinitarian faith is monotheistic, but for Muslims it means blasphemy.
