Gregory of Nazianzusa

Gregory of Nazianzusa (~329 AD - ~390 AD), who is also known as
Gregory the Theologian and Gregory Nazianzen, was born sometime between 326 and 330 CE to Greek parents near to the town of
Nazianzus in southwest
Cappadocia
(
Daley, 2012:1 and
wikipedia).
Gregory pursued his studies at a variety of locations including Caesarea in
Cappadocia,
Caesarea in Palestine, Alexandria, and Athens (
Daley, 2012:4-5). On the way to Athens, he almost died in shipwreck off the coast of Cyprus. During this incident, he dedicated his life
to "God's service" as a Christian (
Daley, 2012:6). In Athens he formed a lifelong friendship with
Basil of Caesarea
and probably encountered future Emperor
Julian the Apostate who was also studying
in Athens at the time (
Daley, 2012:6-7). After returning home, probably between 356 and 358 CE,
Gregory went on to hold a variety of ecclesiastical positions before becoming the Bishop of Constantinople in ~380 CE (
Daley, 2012:7,2 and
wikipedia). Gregory wrote a variety of influential theological works and is noted for his
work on the Trinity. His two part invective against Emperor
Julian the Apostate was composed during
Julian's reign and was probably finished by 364 CE (
Daley, 2012:32-33). This invective included a description of the 363 CE earthquake, an account which, according to
Cain and Lenski (2009), was written within a year of the event.
Gregory
died in ~390 CE.
