The "dialogue with Trypho" of Father Lev Gillet

This article by Paul Ladouceur examines Father Lev Gillet's (1893-1980) engagement in Jewish-Christian dialogue, through a historical and theological study centered on his work *Communion in the Messiah* (London, 1942). The article first traces the biographical context: Lev Gillet's collaboration with Reverend Paul Levertoff in London from 1938 onwards, in a shelter for Jewish refugees fleeing Nazism. It then analyzes the structure and arguments of *Communion in the Messiah*, a work that seeks to establish theological, spiritual, and messianic convergences between Judaism and Christianity, particularly around the themes of the Shekinah and eschatological hope. The article's main contribution is to show how this book, praised for its erudition and depth, constitutes a pioneering contribution to interreligious dialogue, whose relevance remains intact, as evidenced by its reissues in 1999 and 2003.
