Aphrahat was a fourth-century Syriac Christian monk and author of Iranian descent living within the Sasanian Empire. Often referred to as the Persian Sage, he was a prominent figure who lived during the reign of Shapur II. His writings provide a significant look into pre-Arian Syriac theology and reflect the religious landscape of the era. He is recognized as a saint and is commemorated in various Christian traditions, including Catholic, Oriental, and Orthodox churches.
Life and writings

Born near the border of the Roman and Sasanian empires, Aphrahat lived an ascetic and celibate life as part of a communal monastic movement. He is primarily remembered for composing twenty-three religious Demonstrations. These homilies address various aspects of Christian doctrine and practice, including tensions with Jewish-Christian groups. In his work, he frequently utilized the Diatessaron for gospel quotations.
Veneration and legacy
The theological contributions of Aphrahat remain influential, with portions of his eleventh Demonstration being incorporated into liturgy. His fourteenth Demonstration serves as a synod letter, offering historical insight into early church organization. He is associated with the Mar Mattai Monastery and is honored on his feast day, January 29, across several different Christian traditions.
