bishoptheologian

Why Gregory matters

Eastern Orthodoxy gives only three theologians the title 'the Theologian' — John the Evangelist, Gregory of Nazianzus, and Symeon the New Theologian. Nazianzus earned it with five sermons preached in Constantinople in 380 that nailed down what 'three persons, one God' actually means. He didn't want the job (he kept trying to retire to a contemplative life) but when the Trinitarian crisis demanded clarity, he produced it. After him, Trinitarian orthodoxy is settled.
