Letter VI, from Pope Simplicius to Acacius

Synopsis: Simplicius commends Acacius for refusing Timothy Aelurus — condemned both in the matter of the faith and of parricide — entry to any church at Constantinople, and urges him to continue pressing the Emperor Zeno in Simplicius’s name that the decrees of the Council of Chalcedon not be violated by any deception.

Simplicius, bishop, to Acacius, bishop of Constantinople.

Simplicius Commends Acacius for Refusing Timothy Aelurus Communion at Constantinople and Urges Continued Supplication to the Emperor in Rome’s Name

When Our sons — the illustrious man Latinus the patrician, and the distinguished Madusius — were being sent on a public legation, We could not neglect what We attend to with all Our intention. For recently, when the complaint of presbyters and monks concerning Timothy — long ago separated from the universal Church — had come [to Us], We wrote both to the most Christian prince and to Your Charity, that you might resist in every way, lest the audacity of heretics contrive anything against the Chalcedonian Council, dearest brother. And praising the constancy of Your Charity, We recorded that it greatly pleases Us — indeed, the Lord Himself — that you have not permitted a man condemned both in the matter of the faith and of parricide to enter any church at Constantinople.

This We now admonish you again: that when these same writings reach Your Charity — or even while they are on their way — you do not cease to act and make known, in supplication, before the most Christian prince in Our name as well, so that what has been so often and well established should not be violated by any deception. For the certain and singular foundation of his kingdom is this: to preserve unharmed, for the true and eternal King, the council of the priests gathered in the cause of the faith by the divine Spirit.

Notes / Historical Commentary

Letter VI is Simplicius’s short follow-up to Acacius, sent via the Odoacer–Zeno legation that carried Latinus and Madusius as envoys. It was written at the same general moment as Letter V (early 477), during the window between Zeno’s restoration and Timothy Aelurus’s death, when Rome and Constantinople were still working together against the Monophysite party. The letter has two parts: a commendation of Acacius for what he has already done, and an exhortation to continue pressing the emperor.

The commendation is substantive. Acacius has refused to permit Timothy Aelurus to enter any church at Constantinople, and Simplicius names Rome’s approval of this refusal as pleasing to the Lord Himself. The reader should notice the two grounds on which Timothy stands condemned in Simplicius’s framing: not only in the cause of the faith (heresy) but also in the cause of parricide (the murder of Proterius of Alexandria in 457). The doubled condemnation is one Simplicius deploys throughout his correspondence touching Timothy — it appears in Letter IV and again here. Timothy is a heretic and a murderer, and both grounds together justify his exclusion from every church in the capital. Acacius’s refusal is therefore not merely a personal act of pastoral judgment but an enforcement of a settled condemnation that Rome shares and endorses.

The exhortation continues the pattern established in Letter V. Simplicius asks Acacius to press the emperor “in Our name as well” — the delegation language that treats the bishop of Constantinople as Rome’s representative before the imperial court. The reader should notice how consistent this pattern is across Simplicius’s early Acacian correspondence: Rome defines, Constantinople presents Rome’s case to the emperor, the emperor is to act. It is a cooperative model, but one in which the initiative and the definition belong to Rome and Constantinople serves as the channel. The cooperation it presupposes would not survive the next decade; within eight years of this letter, the successors of the cooperating parties would be divided in schism.

The closing political theology deserves attention. Simplicius argues that the emperor’s kingdom rests on a “certain and singular foundation” — namely, his preservation of the Council of Chalcedon, which Simplicius here describes as gathered “by the divine Spirit.” The sentence is a compressed form of the argument Simplicius has been making to every imperial correspondent: the earthly throne is safe only when it preserves the heavenly King’s faith. The characterization of Chalcedon as pneumatically gathered gives the council’s decrees a divine warrant that puts them beyond imperial revision. What was defined by the Spirit cannot be violated by the political authority whose stability depends on honoring it. The emperor who preserves Chalcedon preserves his own kingdom; the emperor who violates Chalcedon violates the foundation of his own rule.
