The dogma of the Holy Trinity has always been at the center of Orthodox theology, which is why it was an endless subjection of reflection for Fr. Dumitru Staniloae, may he rest in peace. The special place that the Trinity occupies in his teaching on the Church makes Fr. Staniloae the theologian par excellence of the Holy Trinity in the contemporary world. In fact, his entire corpus is a mammoth effort to place the unspeakable mystery of the Holy Trinity at the center of all recent Christian life and thought. As with St. Maximus the Confessor, whose work he has translated and commentated on in Romanian, this dogma does not represent an isolated theme for Fr. Staniloae. His exegesis of the Trinity glimmer throughout every chapter of his dogmatic theology. While identifying both a united absolute essence and distinct absolute hypostases at the heart of the Holy Trinity, in the most Orthodox spirit Fr. Staniloae always aimed to bring the living, dynamic personalism of Orthodox Christian theology into the light. Speaking as no one else in contemporary theology has about the infinite value of the person, about its unfathomable depths, and seeing "the undying face of God" in man, Fr. Staniloae can also speak about the perfect love whose only source is the Holy Trinity." - From the foreword by His Beatitude Teoctist, Patriarch of the Romanian Orthodox Church
Fr. Staniloae (1903-1993) is widely considered as one of the greatest Orthodox theologians of the twentieth century. He was Professor of Dogmatics at the Theological Institute in Bucharest, Romania, from 1947 to 1973. In 1990 he was made a Member of the Romanian Academy.
