Life and Ascetic Discipline
According to the chronicle account, Saint John "lived within the city walls for 23 years; his fish was rancid and he did not eat bread. He lived within the city as though in a wilderness, in great silence." His self-imposed regimen consisted of consuming only spoiled fish while abstaining from bread altogether, sustaining a contemplative, silent manner of life despite residing within an urban setting.
He is venerated in the Orthodox tradition as "Venerable Father John." No information regarding his relics or any formal canonization or glorification process is recorded in the available sources.
