Saint Mari, originally named Palut, was a 1st-century Syriac missionary and one of the seventy disciples. After being converted by Thaddeus of Edessa, he was sent to evangelize regions south and east of Edessa. He is recognized as a foundational figure for the Church of the East, having conducted extensive missionary work throughout Syria and Persia, including areas near Nineveh, Nisibis, and the Euphrates. He is traditionally honored as the Apostle of Persia.
Missionary work

Following his conversion, Mari traveled extensively to spread the Christian faith. His ministry covered significant locations such as the Euphrates and Nisibis. He is credited, alongside Thaddeus, with the creation of the Liturgy of Addai and Mari. Historical accounts link his activities to the Apocryphal Acts of Mar Mari, which describe his holy deeds. He is said to have been laid to rest in Dayr-Kuni.
Veneration
Mari is venerated as a saint within several traditions, including the Assyrian Church of the East and the Chaldean and Syro-Malabar Catholic Churches. His legacy remains central to these communities. His feast day is observed on August 4 or August 5, depending on the specific Christian calendar used.
