We are in possession of a considerable body of testimonies from ancient literature bearing on the life and work of Gregory. From these, though they are largely mixed up with the marvellous, we gain a tolerably clear and satisfactory view of the main facts in his history, and the most patent features of his character. From various witnesses we learn that he was also known by the name Theodorus, which may have been his original designation; that he was a native of Neo-Caesareia, a considerable place of trade, and one of the most important towns of Pontus; that he belonged to a family of some wealth and standing; that he was born of heathen parents; that at the age of fourteen he lost his father; that he had a brother named Athenodorus; and that along with him he travelled about from city to city in the prosecution of studies that were to fit him for the profession of law, to which he had been destined. Among the various seats of learning which he thus visited we find Alexandria, Athens, Berytus, and the Palestinian Caesareia mentioned. At this last place-to which, as he tells us, he was led by a happy accident in the providence of God-be was brought into connection with Origen. Under this great teacher he received lessons in logic, geometry, physics, ethics, philosophy, and ancient literature, and in due time also in biblical science and the verities of the Christian faith. Thus, having become Origen's pupil, he became also by the hand of God his convert. After a residence of some five years with the great Alexandrian, he returned to his native city. Soon, however, a letter followed him to Neo-Caesareia, in which Origen urged him to dedicate himself to the ministry of the Church of Christ, and pressed strongly upon him his obligation to consecrate his gifts to the service of God, and in especial to devote his acquirements in heathen science and learning to the elucidation of the Scriptures. On receipt of this letter, so full of wise and faithful counsel and strong exhortation, from the teacher whom he venerated and loved above all others, he withdrew into the wilderness, seeking opportunity for solemn thought and private prayer over its contents. At this time the bishop of Amasea, a city which held apparently a first place in the province, was one named Phaedimus, who, discerning the promise of great things in the convert, sought to make him bishop of Neo-Caesareia. For a considerable period, however, Gregory, who shrank from the responsibility of the episcopal office, kept himself beyond the bishop's reach, until Phaedimus, unsuccessful in his search, had recourse to the stratagem of ordaining him in his absence, and declaring him, with all the solemnities of the usual ceremonial, bishop of his native city. On receiving the report of this extraordinary step, Gregory yielded, and, coming forth from the place of his concealment, was consecrated to the bishopric with all the customary formalities; and so well did he discharge the duties of his office, that while there were said to be only seventeen Christians in the whole city when he first entered it as bishop, there were said to be only seventeen pagans in it at the time of his death. The date of his studies under Origen is fixed at about 234 A.D., and that of his ordination as bishop at about 240. About the year 250 his church was involved in the sufferings of the Decian persecution, on which occasion he fled into the wilderness, with the hope of preserving his life for his people, whom he also counselled to follow in that matter his example. His flock had much to endure, again, through the incursion of the northern barbarians about 260. He took part in the council that met at Antioch in 265 for the purpose of trying Paul of Samosata; and soon after that he died, perhaps about 270, if we can adopt the conjectural reading which gives the name Aurelian instead of Julian in the account left us by Suidas.
The surname Thaumaturgus, or Wonder-worker, at once admonishes us of the marvellous that so largely connected itself with the historical in the ancient records of this man's life. He was believed to have been gifted with a power of working miracles, which he was constantly exercising. But into these it is profitless to enter. When all the marvellous is dissociated from the historical in the records of this bishop's career, we have still the figure of a great, good, and gifted man, deeply versed in the heathen lore and science of his time, yet more deeply imbued with the genuine spirit of another wisdom, which, under God, he learned from the illustrious thinker of Alexandria, honouring with all love, gratitude, and veneration that teacher to whom he was indebted for his knowledge of the Gospel, and exercising an earnest, enlightened, and faithful ministry of many years in an office which he had not sought, but for which he had been sought. Such is, in brief, the picture that rises up before us from a perusal of his own writings, as well as from the comparison of ancient accounts of the man and his vocation. Of his well-accredited works we have the following: A Declaration of Faith, being a creed on the doctrine of the Trinity; a Metaphrase of the Book of Ecclesiastes, a Panegyric to Origen, being an oration delivered on leaving the school of Origen, expressing eloquently, and with great tenderness of feeling, as well as polish of style, the sense of his obligations to that master; and a Canonical Epistle, in which he gives a variety of directions with respect to the penances and discipline to be exacted by the Church from Christians who had fallen back into heathenism in times of suffering, and wished to be restored. Other works have been attributed to him, which are doubtful or spurious. His writings have been often edited,-by Gerard Voss in 1604, by the Paris editors in 1662, by Gallandi in 1788, and others, who need not be enumerated here. The story of the "Revelation" is of little consequence, though, if this were Gregory's genuine work, it would be easy to account for it as originating in a beautiful dream. But it is very doubtful whether it be a genuine work; and, to my mind, it is most fairly treated by Lardner, to whose elaborate chapter concerning Gregory every scholar must refer. Dr. Burton, in his edition of Bishop Bull's works, almost overrules that learned prelate's inclination to think it genuine, in the following words: "Hanc formulam minime esse Gregorii authenticam...multis haud spernendis argumentis demonstrat Lardner." Lardner thinks it a fabrication of the fourth century.
Cave's learned judgment is more favourable; and he gives the text from Gregory of Nyssa, which he translates as follows: "There is one God, the Father of the living Word and of the subsisting Wisdom and Power, and of Him who is His Eternal Image, the perfect begetter of Him that is perfect, the Father of the only-begotten Son. There is one Lord, the only Son of the only Father, God of God, the character and image of the Godhead, the powerful Word, the comprehensive Wisdom, by which all things were made, and the Power that gave being to the whole creation, the true Son of the true Father, the Invisible of the Invisible, the Incorruptible of the Incorruptible, the Immortal of the Immortal, and the Eternal of Him that is Eternal. There is one Holy Ghost, having its subsistence of God, which appeared through the Son to mankind, the perfect Image of the perfect Son, the Life-giving Life, the holy Fountain, the Sanctity, and the Author of sanctification, by whom God the Father is made manifest, who is over all, and in all; and God the Son, who is through all. A perfect Trinity, which neither in glory, eternity, or dominion is divided, or departed from itself."
