St. Gregory Thaumaturgus, Bishop of Neocesarea

St. Gregory Thaumaturgus (c. 213-270 AD) was a 3rd-century bishop of Neocaesarea, now known as Niksar, Turkey. He was renowned for his miraculous abilities, earning him the title "Thaumaturgus" or "Wonder-Worker." Born in Pontus, he studied in Caesarea and was converted to Christianity by Origen. As bishop, he faced pagan opposition but converted many through his preaching and miracles. He is known for moving a mountain to build a church and is the patron saint of architects and civil engineers.
