Some early Christian leaders focused on the strength and attributes of wines. They taught that two "types" of wine should be distinguished: wine causing joyousness and that causing gluttony (intoxicating and non-intoxicating). The hermit John of Egypt (died 395) said: "...if there is any sharp wine I excommunicate it, but I drink the good." Gregory of Nyssa (died 395) made the same distinction between types of wine, "not that wine which produces drunkenness, plots against the senses, and destroys the body, but such as gladdens the heart, the wine which the Prophet recommends".
