The Institute for Orthodox Christian Studies celebrates its 10th Anniversary with a Hierarchical Divine Liturgy (Archbishop Gregorios of Thyateira and Great Britain presiding). Clergy from the Greek Orthodox, the Russian Orthodox and the Antiochian Orthodox Churches co-celebrated in the Divine Liturgy. The Choir sung hymns in Greek, English and Russian. The Sermon was presented by Metropolitan Kallistos of Diokleia, a founding member and Director of the Institute (the Sermon is streamed here in a different video due to technical difficulties).

The Sermon presented by Metropolitan Kallistos of Diokleia at the IOCS 10th Anniversary Hierarchical Divine Liturgy, in All Saints Church, Jesus Lane, Cambridge (10/10/2009).

It is a most eloquent presentation of the Teaching and Learning Manifesto of IOCS as a teaching and learning institution of advanced studies in Orthodoxy.

The IOCS 10th Anniversary Celebrations Lunch Talks videos include the speeches and toasts by the Principal, Professor David Frost, and the Academic Director, Dr. Marcus Plested.
