d.458. Bishop of Jerusalem. Some ten years after his appointment he came to prominence at the Council of Ephesus* (431) where he supported the anti-Nestorian side. At the Robber Synod of Ephesus* (449) his voice was raised for Dioscorus,* but the political opportunism so characteristic of Juvenal's career led to his voting for the former's condemnation at the Council of Chalcedon* (451), which body confirmed the diocese of Jerusalem's jurisdiction over all Palestine. Some monkish followers of Dioscorus so threatened Juvenal's position that imperial help was needed for him to regain control of the see in 453.
