Part 1: The Beginnings -- Our journey begins with the founding of the Church, the spread of Christianity to "nations" by the Apostles, the Gospel and the institution of the Sacraments.

Part 2:  Byzantium -- After the stabilization of the Church, the journey continues through the period of the Nicene Creed, Patristic Scriptures, Divine Liturgy and Icons. During this same period, however, the official division of East and West is witnessed and concludes with a gradual rift in matters of faith, dogma, church customs, politics and culture.

Part 3:  A Hidden Treasure -- The Church becomes the only institution perceived by Greeks as the preserver of their national identity during 400 years of Turkish rule. By the end of the 19th century, a worldwide Orthodox community is born and the Church expands its influence to major social and philanthropic concerns.
