One of the bright and dramatic pages in the history of Parisian Orthodox Theology is the activity of the Fotiy`s Brotherhood (1925 (1923?) – 1980s). However, it has not yet been studied completely. The publication, which is based in particular on archival documents from the personal collection of Nicholay Poltoratsky’s family (1909–1990), who at a certain stage acted as the head of the secret society. Nicholay Poltoratsky returned to Homeland after the Second World War and ended up in Odessa, becoming a center of intellectual and spiritual attraction. Our task is to contribute to the reconstruction of the history of the Fotiy`s Brotherhood. That plot is very important for the history of the Russian religious and philosophical Renaissance. The Brotherhood at different times included A. Stavrovsky, V. Lossky, E. Kovalevsky, P. Kovalevsky, M. Kovalevsky, L. Uspensky, I. Lagovsky, G. Krug, A. Bloom and others. Members of the Brotherhood proposed the project of “Latin Rite Orthodoxy” with elements of the ancient Gallican rite. Such a project was implemented in several French parishes, of which some are still active now. The focus of the paper is on a theoretical analysis of the project to create an Orthodox religious order, connecting loyalty to the Orthodox tradition and an оrientation to the ancient Gallican liturgical rite of the Christian church before the time of schism.
