Saint Gregory of Nazianzus (329–390)

Gregory of Nazianzus ( c. 329[1] – 25 January 389 or 390), also known as Gregory the Theologian or Gregory Nazianzen, was a 4th-century Archbishop of Constantinople. He is widely considered the most accomplished rhetorical stylist of the patristic age. As a classically trained orator and philosopher he infused Hellenism into the early church, establishing the paradigm of Byzantine theologians and church officials.
