On Sunday, January 22, 2006, the Divine Liturgy was celebrated by His Eminence Archbishop Demetrios, providing an experience rare in America: a complete hierarchical Diving Liturgy with authentic antiphonal Byzantine chanting.
Selected video parts of the Sunday Orthros and Divine Liturgy (January 22, 2006, Holy Trinity Church, New Rochelle, New York). Two choirs, made up by several conference participants, chanted antiphonically (i.e. alternate chanting between two choirs or psaltes located on either side of the altar). Lycourgos Angelopoulos led the right choir, and Stelios Kontakiotis, formerly of St. Sophia Cathedral in Washington, D. C., led the left choir. The left choir featured English language transcriptions by Hieromonk Fr. Seraphim Dedes of St. Gregory Palamas Monastery in Mansfield, Ohio.
