Gregory Nazianzen

This 4th-century Archbishop of Constantinople is recognized as a Cappodocian Father and the most accomplished rhetorical stylist of the patristic age. He was a classically trained speaker and philosopher. It was he who infused Hellenism into the early church. Much of his theological work continues to influence modern theologians, especially in regard to the Trinity. He too battled against Arianism, the strongly prevailing heresy of his time.
