Since thou didst desire a poverty like unto Christ's, O wise Father John, thou didst forsake thy parents' wealth; and while holding in thy hands the most holy Gospel, O righteous one, thou didst follow after Christ God while ceaselessly praying to Him for us all.

John the Cave Dweller

Reading from the Synaxarion:

Saint John, who was from Constantinople, was the son of illustrious
parents -- Eutropius the Senator and Theodora. At twelve years of age he
departed secretly from his home and went to the Monastery of the
Unsleeping (see Dec. 29). Aflame with longing for his parents, he returned
after six years to his father's home in the guise of a pauper and
beggar. Living in a small hut at the gates of his parents' house
(wherefrom he is called "hut-dweller"), he remained unknown therein for many
years, and suffered mockery at the hands of those who had been his own
servants. Foreknowing his death, he revealed himself to his parents, and
within a few moments reposed, about the year 450.

Since thou didst desire a poverty like unto Christ's, O wise Father
John, thou didst forsake thy parents' wealth; and while holding in thy
hands the most holy Gospel, O righteous one, thou didst follow after
Christ God while ceaselessly praying to Him for us all.
