In Palestine, about the year 231, he studied philosophy under the great Origen, who led him from the pursuit of human wisdom to Christ, Who is the Wisdom of God. Not long after, he was made Bishop of Neo Cęsarea in his own country. As he lay awake one night an old man entered his room, and pointed to a lady of superhuman beauty, and radiant with heavenly light. This old man was St. John the Evangelist, and the lady told him to give Gregory the instruction he desired. Thereupon he gave St. Gregory a creed which contained in all its fulness the doctrine of the Trinity. St. Gregory set it in writing, directed all his preaching by it, and handed it down to his successors. Strong in this faith, he subdued demons; he foretold the future. At his word a rock moved from its place, a river changed its course, a lake was dried up. He converted his diocese, and strengthened those under persecution. He struck down a rising heresy; and, when he was gone, this creed preserved his flock from the Arian pest. St. Gregory died in the year 270.

The Feast Day of Saint Gregory Thaumaturgus is November 17. The origin of Feast Days: most saints have specially designated feast days and are associated with a specific day of the year and these are referred to as the saint's feast day. The feast days first arose from the very early Christian custom of the annual commemoration of martyrs on the dates of their deaths at the same time celebrating their birth into heaven.
