Cyrille Sollogoub, president of ACER-MJO, traces the key stages of this thinker's life, focusing particularly on the circumstances that led to his ecclesiastical and theological commitment. The central idea is to show how Clément's personal trajectory — marked by a conversion to Orthodox Christianity in adulthood — profoundly shaped his thinking and his work.

This article focuses on the legacy of Father Nicolas Lossky in the specific field of Orthodox liturgical chant. Written in the form of a personal testimony, it is one of the contributions to a collection of texts paying tribute to this significant figure in Orthodox theology and liturgy. The author, Cyrille Sollogoub, highlights Father Nicolas Lossky's singular contribution to the practice of and reflection on liturgical chant, a dimension often less well known than his theological works. The main contribution of this article lies in the documentation of a particular aspect of Lossky's work, allowing for a better understanding of the articulation between his theological thought and his concrete commitment to the musical tradition of the Orthodox Church. It thus offers a complementary perspective on a personality whose influence was felt at several levels of ecclesial life.

This article by Cyrille Sollogoub examines the influence of the Moscow Council of 1917-1918 on the emergence and renewal of Orthodox lay brotherhoods and movements in the twentieth century. Drawing on historical and ecclesiological study, it analyzes two distinct contexts: Soviet Russia, where brotherhoods developed in response to Bolshevik persecution, and the Russian emigration in the West, where they embodied a renewed Orthodox witness. The central idea is that the Council, by rediscovering conciliarity and the responsibility of the laity, directly gave rise to the multiplication of these brotherhoods as living forms of ecclesial expression. The theological contribution of the article lies in its illumination of the structural link between conciliarity and lay brotherhoods, presented as an ecclesiological response to the exit from the Constantinian era, analogous in their function to the monastic communities that emerged at the entry into that same era.

This article examines the different forms of Orthodox liturgical chant practiced in the French language in the context of parish celebrations. Drawing on direct experience in choral direction, the author offers a descriptive and typological study of the repertoires and musical traditions employed in Francophone Orthodox liturgy.

The article provides an overview of existing practices, distinguishing the different styles and musical heritages that coexist within this liturgical space. From a historical perspective, it highlights the pioneering role played by certain communities in the development of Orthodox chant in French, thereby contributing to the documentation of a tradition that is still young but now well established.
