In the Blachernae Church in Constantinople - in the time of the Emperor Leo the Great (457-474) and the Empress Verina and Patriarch Gennadius, two Constantinopolitan nobles, Galbius and Candidus, were travelling in the Holy Land to venerate the holy places there. In Nazareth, they stayed in the house of a Jewish girl who had the vesture of the Mother of God kept in a secret place. Many of the sick and wretched had received healing through prayer and the touching of this vesture. Galbius and Candidus took this holy relic to Constantinople and informed the Emperor and the Patriarch of its existence. It was the cause of great rejoicing in the imperial city. The vesture was ceremonially placed in the Blachernae church (a church built by the Emperor Marcian and Empress Pulcheria on the shore of a bay, and named 'Blachernae' after a General Blacheran from Scetis, who was killed there), and this commemorative feast was instituted.
A contemporary of the great illuminators of the Orthodox Church: Euthymius, Theodosius, Gerasimus, Simeon the Stylite and others. He participated in two Ecumenical Councils: the Third Council in Ephesus [431 A.D.] and the Fourth Council in Chalcedon [451 A.D.]. With great power and zeal, he fought against the blasphemous heresies: in Ephesus against Nestorius who called the Birth-giver of God the Birth-giver of Christ and in Chalcedon against Eutyches and Dioscorus who taught that there was only one nature in Christ, i.e., only a divine nature without a human nature. Following the victory of Orthodoxy at both councils, Juvenal returned to his throne in Jerusalem. Even though the heresies were condemned, the heretics were not eliminated. Through the intrigue and violence of Theodosius, a friend of Dioscorus, Juvenal was banished from the patriarchal throne and Theodosius, on his own, elevated himself in Juvenal's place. In the beginning, this heretic Theodosius was supported by Empress Eudocia, the widow of Theodosius the Younger who, at that time, took up residence in Jerusalem. Hesitant and indiscreet, Eudocia finally went to see St. Simeon the Stylite in order to ask him wherein lies the truth. The saint of God unmasked all the heretical teachings and instructed the empress to adhere to the teachings of Orthodoxy as confirmed at the councils. The empress heeded, repented and she herself became embittered against the false Patriarch Theodosius. During that time Marcian and Pulcheria reigned in Constantinople. A letter from the emperor was sent to Commander Athanasius ordering him to banish Theodosius and to return and reinstate Juvenal to his throne which the commander quickly did. Juvenal governed the Church in Jerusalem for thirty-eight years as its hierarch and at a ripe old age presented himself to the Lord in the year 458 A.D. to receive from Him the reward for great suffering and misery which he had endured for the truth. During the reign of St. Juvenal, the celebration of Christmas was established on December 25.
He was of Greek descent. He prudently governed the Russian Church for twenty years. Photius died in the year 1430 A.D. A week before his death an angel of God appeared to him and informed him of the exact time of his departure from this world.
