Synopsis: Theodosius responds to Valentinian’s Letter LV to affirm that the most reverend patriarch Leo has been informed more broadly and fully of what was discussed, and that the synod decreed at Ephesus — convened because certain persons were disturbing the most holy churches with harmful novelty — was conducted in the presence of the most reverend bishops with great freedom and with the full integrity of truth, those unworthy of the priesthood being removed and those judged worthy being received, so that nothing contrary to the rule of faith or justice was done, all contention having been examined by sacred judgment, and Flavian, who appeared guilty of harmful novelty, having duly received what belonged to him, since with this removed all peace and concord reign in the churches and nothing but truth flourishes.
To my lord Valentinian Augustus — Theodosius.
Theodosius Affirms the Council of Ephesus Was Rightly Convened and Properly Conducted; Flavian Received His Due; Peace Now Reigns in the Churches
That your meekness arrived in Rome and the petition presented by the most reverend patriarch Leo — these have been indicated in the very text of your majesty’s letter. For your safe return to the city of Rome, we render fitting thanks to the divine majesty, most sacred son and venerable emperor.
As to what the aforementioned most reverend man has said — this has been conveyed to him more broadly and fully, as we deemed fit, and he has come to know that we have in no way departed from our ancestral religion and the tradition of our forebears. For we desire nothing other than that the paternal mysteries1 handed down to us through succession be kept inviolably. For this reason — since we recognized that certain persons were disturbing the most holy churches with harmful novelty — we decreed that a synod be held at Ephesus.
In the presence of the most reverend bishops, with great freedom and with the full integrity of truth, those unworthy of the priesthood were removed, and those judged to be worthy were received. We have thus recognized that nothing was done by them contrary to the rule of faith or justice. All contention has been examined by sacred judgment. Flavian, who appeared to be guilty of harmful novelty, received his due. With this removed, all peace and all concord reign in the churches, and nothing other than truth flourishes.
Footnotes
↩Sacramenta paterna — “paternal mysteries,” rendered consistently in this project as “mysteries” rather than “sacraments.” Theodosius is referring to the doctrinal inheritance received through succession — the deposit of faith as defined at Nicaea and Ephesus I — which he presents as what the Ephesine council was convened to preserve. The irony, from Leo’s perspective, is that both sides claim to be defending the received tradition: Theodosius claims Ephesus II preserved it; Leo claims Ephesus II violated it. The substantive dispute is about which council — Nicaea plus Ephesus I plus the Tome, or Ephesus II — correctly articulates what the tradition contains.
Letter LXII is Theodosius’s formal reply to Valentinian’s Letter LV — the most direct Eastern imperial counter to the Western imperial-papal coalition in the post-Latrocinium correspondence. The project’s integrity requires presenting it honestly, and it deserves honest presentation. Theodosius is not acting from malice or ignorance; he is an emperor who authorized a council, received its acts, and believed them canonically sound, and who is now being pressed by his Western counterpart — clearly on Leo’s prompting — to reverse them. His response is measured and theologically coherent on its own terms.
The reader should be cautious about reading this letter as a principled Eastern counter-position to Roman authority. Theodosius is not opposing the Apostolic See; he is defending a council he believes was sound. But the question of what he actually believed — and how freely he was able to form that belief — is complicated by his court environment. The dominant figure at the Constantinople court in this period was Chrysaphius, the imperial chamberlain who had been the personal godson of Eutyches and the primary architect of the Latrocinium. Chrysaphius had everything to lose from a reversal of Ephesus II and controlled much of what reached the emperor. Leo understood this, which is why he worked so persistently through Pulcheria as an alternative channel — she was orthodox, she had genuine influence with her brother, and she was outside Chrysaphius’s orbit. What Theodosius was being told about the council’s proceedings, about Flavian’s guilt, and about Leo’s objections was being filtered through people with a strong interest in the Ephesine settlement standing. His letters are better read as the product of that environment than as a considered theological counter-claim against Rome. The reader who follows the broader history of the Eastern church will recognize in the Chrysaphius episode the early instance of a pattern that would recur with increasing frequency as Constantinople grew in secular and commercial power: court figures — chamberlains, empresses, military strongmen, factional networks — filtering theological questions through political interest, with imperial policy on matters of faith becoming difficult to disentangle from the pressures applied to those who held it. The structural conditions that made Chrysaphius possible in 449 did not disappear with his execution; they were baked into the institutional character of a city that was simultaneously the seat of empire, the center of Eastern commerce, and the residence of the Church’s most powerful bishop after Rome.
What Theodosius does not say is as significant as what he does. He does not dispute Roman authority in principle; he does not claim that the Apostolic See has no right to concern itself with Eastern councils. His defense of Ephesus II is entirely on the merits: the council was properly convened, conducted with freedom and integrity, and its outcome was just. He is saying “there is nothing to correct” rather than “Rome has no standing to correct it.” This distinction matters. The Eastern imperial counter-position, as Theodosius states it here, is a dispute about the facts of a particular case — whether Flavian was rightly deposed — not a principled rejection of the jurisdictional structure Leo claims.
The reader will not miss the historical postscript. Theodosius wrote this letter in approximately April 450. He died on July 28 of the same year. His successor Marcian, who married Pulcheria and shared her theological convictions, authorized the Council of Chalcedon before the year ended — the council that overturned Ephesus II, confirmed Flavian’s orthodoxy, condemned Dioscorus, and adopted Leo’s Tome as its doctrinal standard. The finality Theodosius asserted — “all peace and concord reign in the churches, and nothing but truth flourishes” — was undone within months, under his own successor. Chrysaphius was disgraced and executed shortly after Theodosius’s death, and the court environment that had sustained the Ephesine settlement collapsed with him. The verdict of Chalcedon is the historical judgment on both the letter and the council it defends.
