By the authority of the emperor, a great part of the Eastern Church received and executed this decree; but Irene, who had married Leo the Fourth, son of Constantine Copronymus, though a cruel, ambitious woman, espoused, perhaps out of caprice, the opposite side, and on the death of her husband, during the minority of her son Constantine, who was but ten years old, assumed the regency, and stopped the savage persecution of the monks, and the ruthless destruction of images which had proceeded without intermission through the three preceding reigns. Paul III., patriarch of Constantinople, had been raised to that dignity by the late emperor. Being a timid man, desirous of remaining in favour with court, he had bowed to the will of the emperor in the matter of images. But he was a good and charitable man, greatly beloved by the poor. Finding that the Iconoclasts were now out of favour, and fearing for himself, he suddenly resigned his patriarchal see, and took refuge in a monastery.
The empress and her son visited him, and endeavoured to dissuade him from his intention, but found him resolved. Tarasius, an officer of the court, noted for his piety, was then appointed patriarch, in spite of his urgent remonstrance. He declared that he would not accept the office till a council had been called, which exhibited those marks of being œcumenical which the former council had lacked, and which might compose the differences which had agitated the Eastern Church. This being agreed to, he was solemnly declared patriarch, and was consecrated soon after, on Christmas Day.
His first act was to write synodal letters to the patriarchs of Rome, Alexandria, Antioch, and Jerusalem, convening a general council. Pope Adrian sent two priests to act as his legates, and the Eastern bishops did the same. The council assembled on the 1st August, 786, in the Church of the Apostles at Constantinople, but a tumult having broken out, and the soldiers having besieged the bishops in the church, and endeavoured to break up the council, it was adjourned till the following year, when it met at Nicæa. The papal legates sat in the first place, then Tarasius, patriarch of Constantinople, then the deputies of the Eastern bishops, who were themselves unable to attend because not permitted by the Saracen conquerors, afterwards Agapetus, bishop of Cæsarea, in Cappadocia, John, bishop of Ephesus, Constantine, metropolitan of Cyprus, with 250 bishops and archbishops, and above 100 priests and monks, and two commissioners of the emperor and empress to maintain order.
The first session was held on the 24th September, 787, in the Church of S. Sophia; it opened with the reading of the letter of the empress Irene and the emperor, wherein they assured to the bishops that they had assembled the synod with the consent of the patriarchs, and that they left the bishops at full liberty to speak their minds; that Paul, the last patriarch of Constantinople, acknowledging his fault in having received the decrees of the council of the Iconoclasts, had quitted his see, and had caused Tarasius to be elected in his room; that Tarasius had refused the dignity, but having been urged to accept it, had required a council to be held to suppress the schism which divided the Church on the subject of images; and that, therefore, in accordance with his request, this council was convened. In conclusion, the empress and her son exhorted the bishops to judge truthfully and courageously, in accordance with Catholic doctrine and practice; and they said that letters had been received from Pope Adrian, which should be read to the assembly.
After this many of the prelates who had taken part with the Iconoclasts, or had submitted to the decrees, seeing that the direction of the courtly breeze had changed, veered round with obsequious readiness. Such were, Basil, bishop of Ancyra, Theodosius of Myra, Theodosius of Amorn, Hypatius of Nicæa, and others, who now acknowledged that they reverenced sacred images.
In the next session the letters of Pope Adrian were read, declaring the utility of images as means of teaching the ignorant, and of awakening piety and compunction. He demanded also that all archbishops of his patriarchate should receive ordination from the bishop of Rome, and that the primacy of the see of Rome should receive general recognition, as also that the patriarch of Constantinople should be prevented from assuming the title of "Universal Bishop." These latter articles were not transcribed by the Greek fathers. Dupin, the judicious historian, suggests that probably the legates of the Pope did not judge it prudent at that moment to present them. A letter from Adrian to Tarasius was then read, expressing the trouble given to the Pope by the news of the nomination of a layman to the influential see of Constantinople, and exhorting him to procure the condemnation of the synod which had forbidden images in churches. After the reading of this letter, the Papal legates asked Tarasius whether he approved of it. He answered that he did, and that he did reverently honour the images of Christ, the Holy Virgin, and the saints, but that to God alone was due true adoration and worship (latria). Of this the synod approved. Our English word worship has got at the present time a meaning which it had not of old. Worship now means to adore as God, with supreme reverence; and such worship may not be given to creatures, however exalted; but the old signification of the word had not this force, but was synonymous with reverence. Thus, in the Anglican prayer book, in the marriage service, the husband says to the wife, "With my body I thee worship," i.e., honour; and magistrates are called the "worshipful." When Protestants accuse Catholics of worshipping images, in one sense they are right, but in another sense they are wrong. Catholics do worship sacred images so far as to render them respect and honour, but they do not give to them that honour which is implied by the word "worship" in its modern sense. In the old signification of the word, the sailor worships the quarterdeck when he touches his cap on passing it, the soldier worships the royal standard when he presents arms to it, and the peers the throne when they bow to it on taking their places in the House of Lords.
In the third session of the council, a letter from the patriarch of Jerusalem, approved by his bishops, was read, wherein he acknowledged that reverence and honour were to be shown to sacred images.
In subsequent sessions the acts of the Iconoclastic Council at Jerusalem were examined and refuted in order, and the council closed with the usual acclamations and prayers for the prosperity of the emperor and empress; after which synodal letters containing the decrees were sent to all churches. Pope Adrian approved of all that had been decreed, and sent copies of the Acts into France, where pictures and images were used historically, but no honour, such as burning candles or offering of incense before them, was allowed. On receiving these copies, Charlemagne wrote, or caused to be written, or put forth under his name, a work containing an examination of the decrees of the second council of Nicæa, by some of the bishops, of whom Alcuin was chief. This contained a repudiation of these Acts, and a rejection of image-worship. It maintained that respect was due to pictures and statues of the Saviour and the Saints, but refused the right of offering them any sort of religious honour, as by lighting candles and incensing them. This work was presented to Pope Adrian by Engilbert, the ambassador of Charlemagne, and it drew forth from the pope an answer which, however, did not alter the practice of the Gallican Church, for in the Council of Frankfort, held in 794, the decrees relative to the worshipping of images passed by the second Council of Nicæa were rejected, as was the case again in a council held at Paris, in 824. Tarasius, in the meantime, obedient to the decrees of the synod, restored holy images throughout the extent of his patriarchate. His life was a model of perfection to both clergy and laity. He lived a quiet, austere life, in the midst of magnificence and luxury. He reduced to the smallest possible amount the expenses of his household, and gave to the poor what he had economised. He often took the dishes of meat from his table to distribute among them with his own hands: and he assigned them a large annual revenue. And that none might be overlooked, he visited every house and hospital in Constantinople. His discourses turned on the mortification of the senses, and he was particularly severe against all theatrical entertainments, which served then to encourage and diffuse licentiousness. Some time after, the emperor became enamoured of Theodota, a maid of honour to his wife, the empress Mary, and, after having spent seven years in marriage, in 795, he resolved to divorce the empress. He used every effort to gain the patriarch. He sent an officer to him to inform him that a plot of the empress to poison him had been discovered. S. Tarasius, however, received the request to divorce the emperor, and marry him to Theodota, with a stern refusal. "Tell him that I will rather suffer death and all manner of torments than consent to his design." The emperor, hoping to prevail with him by flattery, sent for him to the palace, and said, "I can conceal nothing from you, whom I regard as my father. No one can deny but I may divorce one who has attempted my life. The Empress Mary deserves death or perpetual penance." He then produced a vessel, full of the poison, which he pretended she had prepared for him. The patriarch, with good reason, judging this to be an attempt to impose upon him, answered, that he was too well convinced that his passion for Theodota was at the bottom of all his complaints against the empress. He boldly declared to Constantine that even if she were guilty of the crime laid to her charge, a second marriage during her lifetime would be adulterous. The monk John, who had been legate of the Eastern patriarchs in the council at Nicæa, being present, also spoke resolutely to the emperor, who was so irritated that he drove them both out of his presence, and John narrowly escaped with his life. As soon as they were gone, he turned the empress Mary out of the palace and obliged her to assume the veil. Tarasius persisted in his refusal to marry him to Theodota, and the ceremony was performed by Joseph, the treasurer of the church of Constantinople. The patriarch became thenceforth an object of persecution to the emperor, who placed spies about his person, suffered no one to speak with him without their leave, and banished many of his relations and servants. This confinement gave the patriarch more leisure for prayer and contemplation. In the meantime, the ambitious Irene, discontented at being no longer at the head of the administration, formed a conspiracy to dethrone her son. The secret was faithfully kept above eight months, till the emperor, suspicious of his danger, escaped from Constantinople, with the design of appealing to the provinces and armies. By this hasty flight the empress was left on the brink of a precipice. She addressed a private epistle to the friends whom she had placed about his person with a menace that, unless they accomplished, she would reveal, their treason. Their fear rendered them intrepid. They seized the emperor on the Asiatic shore, and transported him to Constantinople, where his mother and the other conspirators decided to render him incapable of the throne by blinding him. Her emissaries assaulted the sleeping prince, and stabbed their daggers into his eyes. He survived for several years, oppressed by the court, and forgotten by the world; whilst his unnatural mother resumed the sovereign power, of which he had divested her by becoming of age. She reigned for five years, during which she recalled all the banished, and favoured the Catholics. But she was in turn conspired against by the high treasurer, Nicephorus, who was secretly invested with the purple, and crowned at S. Sophia by the patriarch. The empress was sent into exile in the isle of Lesbos, where she was obliged to earn a scanty subsistence by the labours of her distaff, till her haughty spirit consuming her, she died of grief.
Under Nicephorus, S. Tarasius persevered peaceably in his practices of penance, and in the functions of his pastoral charge. Through his last sickness he continued to offer daily the holy Sacrifice as long as he was able to move. A little before his death he fell into a trance, as the author of his life, who was an eye-witness of the scene, relates, wherein he was heard disputing with a number of accusers, very busy in sifting his whole life, and objecting to his actions. He seemed to be in fear and agitation, and defending himself against everything laid to his charge. This filled all present with fear, seeing the endeavours of the enemy of man to find some condemnation in the life of so holy and so irreprehensible a bishop. But a great serenity succeeded, and the holy man gave up his soul to God in peace, on the 25th of February, in 806, having sat twenty-one years and two months. God honoured his memory with miracles, some of which are related by the author of his life. His festival began to be celebrated under his successor.
