Babai The Great

Babai the Great (ca. 551 – 628) was an early church father of the Church of the East. He set several of the foundational pillars of the Church, revived the monastic movement, and formulated its Christology in a systematic way. He served as an unofficial head of the Nestorian Church from 611 to 628 AD, leaving a legacy of strong discipline and deep religious Orthodoxy. He is revered in the modern Assyrian Church of the East.
