[1] Theodosius was a monk at a monastery near Jerusalem before he was elected the successor to Patriarch Solomon in 864.
Theodosius was represented at the council held in Constantinople between 869-870 by his legate, syncellus Elijah.
Elijah signed the decisions of the council that deposed Patriarch Photius of Constantinople and decreed that Patriarch Ignatius was improperly deposed.
During the time of Theodosius' episcopate, the Church of Jerusalem apparently was experiencing peace and tranquility based on what was said in Theodosius' correspondence to Patriarch Ignatius and that he was able to send three monks to Western Europe to collect funds for the Church of Jerusalem.
