Youhana was a proficient scholar and illustrious theologian and deeply versed in religious studies. He became a monk at the Monastery of Mor Hananyo near Mardin around 825 , the Syriac Orthodox Patriarch Dionysius of Tell Mahre ordained him a metropolitan of Dara which he administered for thirty five years. He is thought to have died in the year 860 and this date is confirmed by the ordination of his successor Athanasius Hakim around the same year.
Youhanna was the person who requested Patriarch Dionysius of Tell Mahre to write his chronicles. In his introduction to these chronicles, the Patriarch testified to Youhanna's love and pursuit of knowledge from youth until old age.
