Khajag Barsamian was born in Arapkir, Turkey on July 4, 1951. At the age of 13, he began his religious studies at the Holy Cross Armenian Seminary in Istanbul. Encouraged by Archbishop Shnork Kaloustian (the late Armenian Patriarch of Constantinople), he went to Jerusalem to study at the Seminary of the St. James Armenian Patriarchate. He was ordained a celibate priest in 1971 and achieved the ecclesiastical degree of vartabed two years later. His educational pursuits have led him throughout the United States and Europe. Concurrent with and subsequent to his education, he has taken on pastoral duties in the Middle East and throughout the Eastern Diocese of the Armenian Church of America.
Khajag Barsamian was elected as Primate of the Diocese of the Armenian Church of America in the spring of 1990 (succeeding Abp. Torkom Manoogian), and was subsequently elevated to the rank of bishop by H.H. Vasken I, Catholicos of All Armenians. In 1992, he received the rank of archbishop. He is currently serving his seventh four-year term as chief bishop of the largest diocese of the Armenian diaspora. Archbishop Khajag has made pastoral visits to St. Hagop church on dozens of occasions, and oversaw the blossoming of the community into a healthy and vibrant parish.
