Depuis 1953, les Semaines d'études liturgiques, organisées à l'Institut de Théologie orthodoxe Saint-Serge à Paris, réunissent des chercheurs principalement chrétiens. Les participants sont invités à examiner ensemble, sous un angle oecuménique et avec une approche scientifique, des documents liturgiques et des pratiques observées hier ou aujourd'hui par des communautés chrétiennes. Le but de ces rencontres, animées par un fervent espoir de dépassement des incompréhensions, est une découverte réciproque des diverses traditions liturgiques et de leurs possibles convergences. The 59th Semaine d'études liturgiques (Week of Liturgical Studies) offered its participants an opportunity to reflect on the issue of reception of the work of several known liturgists in various communities. These pages contain basic introductory presentations, followed by other studies of examples addressing liturgists and reputed liturgiologists, and the examination of some specific aspects concerning the concrete reception of the results of scholarly studies in liturgy. Since 1953, the Semaines d'études liturgiques organized at the Orthodox Theological Institute of Saint Serge in Paris bring together mainly Christian researchers. Participants are invited to examine together liturgical documents and observed practices, yesterday or today, by Christian communities, from an ecumenical perspective and with a scholarly approach. The purpose of these meetings, animated by a fervent hope of overcoming misunderstandings, is a mutual discovery of the various liturgical traditions and their possible convergences
