Sacrosanctum Concilium (SC) was the first document promulgated by the Second Vatican Council. The impact of this document was broad and ecumenical - the liturgical reforms approved by the Council reverberated throughout Christendom, impacting the order and experience of worship in Reformed and Orthodox Churches. This study examines Orthodox liturgical reform after Vatican II through the lens of Catholic-Orthodox ecumenical dialogue. The study presents the history of liturgical reform through four models: the liturgical reforms of Alexander Schmemann; the alternative liturgical center in the Russian Orthodox Church Outside of Russia (ROCOR); the symposia on liturgical rebirth authorized by the Church of Greece; and the renewed liturgy of New Skete Monastery. Following a discussion of the main features of liturgical reform, catechesis, ars celebrandi, and the role of the clergy, Denysenko concludes with suggestions for implementing liturgical reform in the challenges of postmodernity and in fidelity to the contributions of Catholic-Orthodox ecumenical dialogue.
