Dorotheus of Gaza was a sixth-century Christian monk and abbot who lived near Gaza. Born into a wealthy family in Antioch, he received a classical education that included rhetoric and medicine. After joining the monastery of Seridus, he transitioned from a life of luxury to one of ascetic discipline. He eventually served as an overseer and established a hospital within the monastic community. Known for his spiritual maturity, he acted as a mentor to younger monks and maintained close ties with the desert elders Barsanuphius and John the Prophet.
