Sebastian Dabovich was a missionary priest and monk, generally identified as the first person born in the United States to be ordained an Orthodox priest and the first American-born man to be tonsured an Orthodox monk. Born in San Francisco in 1863 to Serbian immigrant parents and baptized John (Jovan), he was educated at the theological academies of Kiev and St. Petersburg in Russia before returning to North America to serve. He is commemorated on November 30.
Tonsured a monk in 1887 with the name Sebastian and ordained to the diaconate while still a student in St. Petersburg, he was ordained a hieromonk in 1892 by Bishop Nicholas (Ziorov). He labored within the Russian Orthodox mission in North America, serving in San Francisco, Minneapolis, and Sitka, and in 1894 established a Serbian parish in Jackson, California, in honor of St. Sava of Serbia. In 1905 he was made head of the Serbian mission in America and elevated to archimandrite by Archbishop Tikhon, the future patriarch of Moscow.
An indefatigable traveler, he crossed between the continents repeatedly in the course of his ministry, journeying to Serbia, Russia, and Japan, and helped to plant Serbian Orthodox communities across the American West and Midwest. He was also among the earliest to publish accounts of Orthodox faith and worship in English. In later years he served as a military chaplain to Serbian forces and eventually withdrew to the Monastery of Zica in Serbia, where he reposed in 1940. His relics were returned to the parish he had founded in Jackson, California, in 2007, and he was glorified as a saint by the Serbian Orthodox Church in 2015.
