To Alexander of Hierapolis, Standing by His Pledges

I think that the most holy and venerable bishop, my lord John, must have been more pleased than anyone that I refused either to consent to the condemnation of the most holy and venerable bishop Nestorius or to break the pledges made at Tarsus, Chalcedon and Ephesus. [a] He remembers too what was often received from us at Antioch after our departure. So let no one deceive your holiness into believing that I would ever do this, for God is without doubt on my side and strengthening me.
