Claim: Dalmatius of Constantinople was married with a family before receiving a call to monastic life, he was also an opponent of the Nestorian heresy ( teachings of Christian theologian  Babai the Great).
Evidence: He was married with a family. Saint Dalmatius (died AD 440) was archimandrite of the Dalmatian Monastery in Constantinople. Experiencing a call to monastic life, he received instruction from Isaac of Dalmatia. Like most of the city's monks, he was an opponent of the Nestorian heresy, and he played an important role in the downfall of Nestorius. 
Babai the Great (ܒܐܒܐܝ ܡܚܡܘܕܐ c. 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 a monastic visitor and coadjutor with Mar Aba as unofficial heads of the Church of the East (often unfortunately, and incorrectly, called the "Nestorian Church" by those in the West) after Catholicos Gregory until 628 AD, leaving a legacy of strong discipline and deep religious Orthodoxy. Babai the Great and Mar Aba administered the Nestorian Church for 17 years. To defend and clarify the Nestorian tradition against Henana's Origenism and the advancing Monophysites, Babai the Great produced some 83 or 84 volumes of writing.
