Archimandrite Irineu [Duvlea] was born in 1962 to John and Aurelia Duvlea. In 1981, he entered the Theological Seminary in Cluj Napoca. After graduating from the seminary in 1987, he continued his studies at the Andrei Saguna Theologizcal Institute in Sibiu, from which he graduated in 1991.
In 1980, he entered the Brancoveanu Monastery at Sambata de Sus, Brasov County, Romania, where he was ordained to the Holy Diaconate by His Emimence, Archbishop John of Helsinki, Finland on behalf of His Eminence, Metropolitan Antonie [Plamadeala] of Transylvania on May 3, 1983. Three weeks later he was tonsured to monastic rank by His Grace, Bishop Lucian of Fagaras. He was ordained to the Holy Priesthood by Metropolitan Antonie in the Metropolitan Cathedral of Sibiu on November 17, 1984.
On August 15, 1988, he was named Protosyngelos by Metropolitan Antonie. On January 1, 1993, he was appointed Hegumen of the Brancoveanu Monastery and was charged with overseeing the life of 15 neighboring monasteries and 10 sketes. In this capacity, he tonsured 30 monks and 15 nuns and installed most of the abbots and abbeses of the monasteries in the Sibiu Diocese. On August 15,1993, he was named Archimandrite of the monastery on the occasion of its consecration by His All-Holiness, Ecumenical Patriarch Bartholomew and His Holiness, Patriarch Teoctist of Romania, and was presented with a patriarchal cross by the Ecumenical Patriarch. On September 24, 2000, the Holy Synod of Romania awarded him the right to wear a mitre.
Archimandrite Irineu made two pilgrimages to Mount Athos and, in 1998, he visited monasteries in Bulgaria and Greece and made a pilgrimage to the tomb of Saint Nicholas in Bari, Italy.
As head of the Brancoveanu Monastery, Father Irineu hosted several patriarchs, including His All-Holiness, Ecumenical Patriarch Bartholomew; His Holiness, Patriarch Parthenius of Alexandria; His Holiness, Patriarch Ignatius of Antioch; His Holiness, Patriarch Pavle of Serbia; and His Holiness, Patriarch Maxim of Bulgaria. Among the other ranking Church dignitaries he hosted there were Archbishop Nathaniel of Detroit; His Eminence, Metropolitan Antonios [Schedrawui] of Mexico; and Archbishop John of Finland. Among the civic leaders whom he received at the monastery were His Majesty, King Michael; the presidents of Romania; and numerous prime ministers.
When Archbishop Nathaniel established the Center for Orthodox Christian Studies at Saint Andrew’s House in Detroit in the late 1990s, it was his dream to provide a monastic presence. On February 23, 2001, Archimandrite Irineu and a group of monks from Romania were granted a canonical release from the Patriarchate of Romania in order to establish a monastic community at the Center, named in honor of the Holy Ascension. Archimandrite Irineu was appointed Abbot of the new community, where he has labored tirelessly to offer hospitality and comfort not only to the Romanian community, but to the entire Orthodox population of Greater Detroit and the Midwest.
His Beatitude, Metropolitan Herman, Primate of the Orthodox Church in America, presided at the consecration of Archimandrite Irineu [Duvlea] to the episcopacy at Saint George Cathedral on November 1-2, 2002.
