Bishop Auxentios (Matthew Gates Chapman) is 63 years of age and a convert to Orthodoxy. He was born in Cleveland, Ohio. He graduated from University School, a private preparatory school in Hunting Valley, Ohio, and went on to complete his undergraduate education at Princeton University, where he studied mathematics and religion. At Princeton, where he also converted to the Orthodox Faith, he was a student of the late Protopresbyter Georges Florovsky, who served on his thesis committee in the department of religion, and of the Most Reverend Chrysostomos, former Metropolitan of Etna, then a layman, preceptor, and doctoral candidate in the department of psychology. He holds a Licentiate in Theology from the Center for Traditionalist Orthodox Studies in Etna, California, and received his doctoral degree in liturgics at the Graduate Theological Union, Berkeley.
His Eminence was ordained a Hierodeacon in 1976, a Hieromonk in 1977, and Titular Bishop and assistant and secretary to the then Archbishop (later Metropolitan) Chrysostomos of Etna in 1991. He is the author or co-author of a dozen books, including a volume on the Rite of the Holy Fire in the Church of the Resurrection in Jerusalem, taken from his doctoral dissertation, and a score of articles in academic journals. He serves as Director of the Center for Traditionalist Orthodox Studies and is editor of its triannual journal, Orthodox Tradition.
Bishop Auxentios is one of five siblings, one an attorney and investor, another an insurance executive, one a corporate executive, and another an Anglican clergyman. His father, George Byron Chapman, Jr., is deceased, but his mother, Ann Whitman Chapman, daughter of the American artist Paul Whitman, lives in Aurora, Ohio, where His Eminence was reared.
