Conversion and Monastic Life
According to the synaxarion, Dometius lived in Persia in the fourth century and was converted to the faith by a Christian named Uaros. He afterward left Persia for Nisibis in Mesopotamia, where he received baptism and took monastic vows.
He later joined the monastery of Saints Sergius and Bacchus in Theodosiopolis, governed by the austere archimandrite Urbelos. Ordained a deacon, he fled to a remote Syrian mountain near Cyrrhus rather than accept ordination to the priesthood.
From his mountain refuge he attracted followers and was known for working miracles. Many pagans were brought to faith in Christ through him, and people sought him out for healing and spiritual guidance. He lived with two disciples who shared his ascetic life.
