Why Gregory matters
Gregory of Nazianzus gave the church some of its clearest language for the Trinity. In Constantinople in 380, with Nicene Christians still under pressure, he preached the Five Theological Orations that explained how Father, Son, and Spirit are distinct without dividing God. He did not want an imperial career and repeatedly tried to withdraw from public office, but the crisis demanded someone who could speak precisely. After Gregory, loose Trinitarian language became much harder to defend.
