Isaiah of Ostrog
About Isaiah of Onogošt
Isaiah of Onogošt, also known as Isaiah of Ostrog, was a Serbian Orthodox monk and ascetic who lived between the late 16th and early 17th centuries. He is venerated as a saint within the Eastern Orthodox Church, with his feast day observed on May 11 (April 28 Old Style).
Life and Historical Context
Historical accounts of Saint Isaiah's life are sparse, but it is preserved that he was born in the village of Popi, near Nikšić. He became a monk and retreated into the rugged highlands of Ostrog, a move likely prompted by a desire to escape Ottoman rule. Within this remote location, he established a small church dedicated to the Entry of the Most Holy Theotokos into the Temple, where he lived as an ascetic until his death.
Legacy
Following his death, the Turks reportedly burned his relics at Planinica, between Ostrog and Nikšić, in an attempt to suppress the growing veneration of him as a saint. Despite these efforts, his spiritual legacy endured. Later, Saint Basil of Ostrog chose the very site of Isaiah's hermitage as the location for the renowned Ostrog Monastery. It is noted that Isaiah's grandson later became a hieromonk at Ostrog Monastery, taking his grandfather's name in his honor. An inscription at the church of the Holy Cross at Ostrog refers to Saint Isaiah as the "Holy and Venerable Father of ours Isaiah of the village of Popi." The first service dedicated to Saint Isaiah was held in 2015 during the consecration of a chapel dedicated to him at the Upper Ostrog monastery, where regular services have been held annually since.
