Grigorios Nazianzinos

Gregory of Nazianzus (c. 329 – January 25, 389 or 390), also known as Gregory the Theologian and Gregory of Nazianzen, was the Archbishop of Constantinople in the 4th century AD. He is widely regarded as the most talented orator among the Church Fathers. As a classically trained speaker and philosopher of Hellenism, he managed to blend Hellenism with the early church of the Byzantine Empire. Gregory had a significant impact on the development of Trinitarian theology among both Greek-speaking and Latin-speaking theologians and became known as the "Trinitarian Theologian." Most of his works continue to influence contemporary theologians, particularly regarding the three Persons of the Holy Trinity. He was friends with two brothers, Basil and Gregory. Gregory is a saint in both the Eastern and Western Christian Churches. In the Roman Catholic Church, he is considered one of the Doctors of the Church. In the Eastern Orthodox and Western Catholic Churches, he is known as one of the Three Holy Hierarchs, along with Basil the Great and John Chrysostom
