Here is a little blurb about the Patriarch also from his website:
The Ecumenical Patriarchate is the primary ecclesiastical centre of the Orthodox Church throughout the world, tracing its history to the Day of Pentecost and the early Christian communities founded by the Apostles of Jesus Christ. According to tradition, the “First-Called” of these Apostles, Andrew, preached the Gospel around Asia Minor, the Black Sea, Thrace and Achaia, where he was martyred. In 36AD, he founded the Church on the shores of the Bosphorus in the city known then as Byzantium, later Constantinople and today Istanbul. St. Andrew is the Patron Saint of the Ecumenical Patriarchate; his Patronal Feast is celebrated on November 30.
