St. Gregory Palamas learned much through heavenly revelations. After he had spent three years in stillness in a cell of the Great Lavra, it was necessary for him to go out among men and benefit them with his accumulated knowledge and experience. God revealed this necessity to him through an extraordinary vision: One day, as though in a light sleep, Gregory saw himself holding a vessel in his hand full to overflowing with milk. Gradually, the milk turned into wine which likewise spilled over the rim, and drenched his hands and garments. Then a radiant youth appeared and said: "Why would you not give others of this wonderful drink that you are wasting so carelessly, or are you not aware that this is the gift of God's grace?" To this Gregory replied: "But if there is no one in our time who feels the need for such a drink, to whom shall I give it?" Then the youth said: "Whether there are some or whether there are none thirsty for such a drink, you are obligated to fulfill your debt and not neglect the gift of God." Gregory interpreted the milk as the common knowledge (of the masses) of moral life and conduct, and the wine as dogmatic teaching.
