Gregory Thaumaturgus (c. 210–270) was an influential bishop and missionary in Neocaesarea, Pontus (modern Niksar), in northern Cappadocia. Through powerful miracles, Gregory converted the pagans of Pontus to Christianity. He had a profound effect on the later Cappadocian Fathers. He became a famous patron saint in later Church history, and many of his writings were preserved.
Around AD 210, Gregory was born into an affluent pagan family in Pontus (a province of Cappadocia from Hadrian to Diocletian). He studied rhetoric and Roman law, so he knew both Greek and Latin. At some point, the Cappadocian bishop Firmilian befriended the young Gregory, thereby introducing him to Christianity and to his friend Origen, the famous Christian philosopher.
Study with Origen
In the early 230s, Gregory traveled to Beirut to further study Roman law. However, instead, he studied under the famous Christian philosopher Origen in Caesarea of Palestine. Eusebius describes Gregory and his brother Athenadore as “the most distinguished” of Origen’s many students. They “both were strongly engrossed in Greek and Roman studies, but Origen instilled in them a love of philosophy and convinced them to exchange their previous passion for theological study” (CH 6:30).
Gregory studied with Origen for five years (c. 233–38) and was likely baptized at that time. Before departing from Origen’s school, Gregory delivered his famous Address of Thanksgiving to Origen. Gregory esteems Origen as a father-like figure and a wise philosopher who masterfully opened his mind to divine truths. The panegyric speech presents us with the most extensive historical description of Origen and his instructional methods.
Bishop at Neo-Caesarea
Gregory returned to Pontus and pursued the philosophical life of an ascetic monk. A true student of Origen, Gregory aspired to a life of contemplation and renunciation. However, against his preference, Gregory was appointed bishop of Pontus. He accepted church ordination after receiving a vision of the Virgin Mary and the apostle John.
Gregory’s supernatural ministry garnered him the nickname “Wonder-Worker” (Greek, Thaumaturgus). Gregory began his ministry with only 17 Christians in Pontus. However, by the end of his ministry, all but 17 people in Pontus had become Christian. His more famous miracles include stopping the raging Lycus River with his staff, drying up a lake to resolve a dispute, and smashing the gods in a pagan temple. One aspect of Gregory’s missionary strategy for attracting pagan Greeks was instituting martyr-feasts as public celebrations—a common practice in early Christianity.
Although Gregory was trained in Alexandrian-style speculative theology, his writings emphasize the pastoral and moral aspects of the faith. The goal of the Christian life, in Gregory’s words, was “to come to God and remain in him, having been made like him by a clean mind.” Philosophy and contemplation, as Gregory learned from Origen, were important means of accomplishing true piety. Gregory, being an early ascetic, spoke about overcoming the impulse of the flesh and renouncing wealth as pathways to true piety and union with God.
Gregory had ascetic and monastic impulses. He emphasized communal relationships and always ministered with associates. Even before Basil the Great famously spread coenobitic monasticism throughout Cappadocia, Gregory had established several monastic-like communities in northern Cappadocia.
As bishop, Gregory led the church during difficult seasons. Like other bishops of his day, Gregory evaded Roman authorities during the Decian persecutions (250–51). Then, in 257, the residents of Pontus endured Gothic raiding. In the aftermath, Gregory wrote a letter of church rules (“canons”) addressing issues of property rights. He indicates that the entire community is responsible for individual rights.
In AD 264 and 268, Gregory participated in the two synods of Antioch, led by his fellow Cappadocian, Firmilian (Eusebius, CH 7.14, 28). Gregory died after 270 and requested that the location of his grave remain a secret, so as to avoid posthumous veneration.
Gregory’s greatest legacy was his influence upon Basil of Caesarea and Gregory of Nyssa, two of the “Cappadocian Fathers.” In terms of the institutional church of Cappadocia, Gregory bequeathed an established community to successive bishops. St. Macrina the Elder, the grandmother of Basil and Gregory, studied under Gregory of Thaumaturgus. She transmitted Gregory’s teachings to her children and grandchildren, including Basil and Gregory.
On the feast day of St. Gregory in 380, Gregory of Nyssa delivered the hagiographic homily The Life of Gregory the Wonderworker to the church in Pontus. To extol Gregory’s nobility and virtue, Gregory of Nyssa compiled The Life from popular stories about Gregory circulating in Pontus and retold by Macrina. Gregory of Nyssa’s oration Life, translated into several ancient languages, is the reason why Gregory’s fame spread and he became a famous saint in Church history.
In Cappadocian cave churches, Gregory appears in Ηidden Church (Göreme), St. John’s Church (Gülşehir), Bahattin’s Hayloft (Belisırma) and Column Church (Belisırma).
