MUNHALL, Pa. — Archbishop Alexander Golitzin of the Bulgarian Diocese of the Orthodox Church in America will be the main speaker at the 18th annual Sts. Cyril and Methodius Lecture of the Byzantine Catholic seminary May 16, 7 p.m., at St. John Cathedral Center, 210 Greentree Road, in Munhall. His theme is, “The Place of the Presence of God: Aphrahat of Persia’s Portrait of the Christian Holy Man.” Aphrahat the Persian is the earliest writer in Christian Syriac of whom there is proof. Writing in the 330s and 340s, his works are notable for their freedom from the lexicon and Greek thought. Although unacquainted with Greek and Latin patristic literature, Aphrahat possessed considerable authority in the church of the Persian Empire. Free admission.
