Travels and Ascetic Life
The synaxarion frames Gregory's life as a succession of journeys undertaken in defense of his Orthodox faith during the iconoclast period. Leaving Crete, he is said to have gone first to Seleukia, then to Jerusalem, where by tradition he spent roughly twelve years before continuing to Rome and entering a monastery.
His final settlement came through Saint Michael of Synnada, who brought him to a monastery on the Cape of Akrita on the Sea of Marmara. It is from this place that he is surnamed Akrita. Later reference works associate the site with the Akritas promontory near the eastern shore of the Sea of Marmara. The sources record that he accomplished great ascetic deeds there before his death around 820.
