The Early Church and Peter's Primacy

Letter CXXXVII, from Pope Leo to Emperor Marcian

Synopsis: Leo thanks Marcian for pressing the Paschal inquiry in Alexandria, reports that he has given his consent to the Egyptian computation for the sake of unity rather than because the argument was decisive, and attaches a further request that the financial administrators of the Constantinopolitan church not be brought before civil judges but have their accounts examined by priestly examination according to established custom.

Leo, bishop, to Marcian Augustus.

Chapter I: Leo’s Paschal Solicitude Is Resolved Through Marcian’s Action; Leo’s Consent Given for the Sake of Unity

My solicitude — which I had maintained regarding the Paschal observance — I rejoice to see resolved through the holy study of your clemency in response to my petition, since you commanded that inquiry be made more diligently in the Alexandrian church as to whether the coming Paschal feast could rightly be celebrated on the eighth day before the Kalends of May — according to the definition of Bishop Theophilus — against the ancient observance, since from the Lord’s Passion in all our annals the fifteenth day before the Kalends of May is found recorded. But since the Egyptians prefer another reckoning, I accommodated my consent — so that no discrepancy might arise through the provinces regarding the observance of so venerable a feast — to the end that the greatest mystery of the Lord’s Resurrection be celebrated nowhere on a different day, that nothing among the Lord’s priests be variable in so great a solemnity, and that throughout all the churches prayer be offered equally to our God for the prosperity and kingdom of your piety.

I make known that I have received the letters of my brother and fellow bishop Proterius, bishop of the city of Alexandria, in response to which I have written to your piety with my consent — not because the argument has manifestly demonstrated this, but because the care for unity, which we guard above all things, has persuaded me.

Chapter II: Leo Asks That the Oeconomi of the Constantinopolitan Church Be Examined by Priests, Not Civil Judges

I have also judged it reasonable to attach to this letter a renewed request on a matter I had previously petitioned of your piety: that you not permit the oeconomi of the Constantinopolitan church to be heard before civil judges — a novel departure, especially in the times of your piety — and that you remove this injury as well from the sacred orders; but that the accounts of the church be examined by priestly examination according to established custom, as you command.

Dated the fourth day before the Kalends of June, in the consulship of the most illustrious Aetius and Studius.

Notes / Historical Commentary

Letter CXXXVII is the third letter of the May 29, 454 dispatch — alongside CXXXV to Anatolius and CXXXVI to Marcian on the Anatolius restoration. Its two chapters cover the Paschal resolution and the oeconomi question respectively, making it a compact administrative letter that closes the Paschal inquiry sequence opened by Letters CXXI, CXXII, and CXXXIII.

Chapter I’s most significant sentence is the careful specification of the grounds for Leo’s consent. He does not say the Egyptian calculation is correct; he says he accommodated his consent for the sake of unity. The distinction matters: Leo’s consent is the operative element that makes the computation acceptable for universal observance, and he names it explicitly as a deliberate choice rather than as a recognition of the argument’s cogency. This is consistent with the project’s broader pattern — Leo’s consent, throughout the corpus, is a volitional act that determines what is binding, not a registration of what external authority has already determined.

Chapter II’s request about the oeconomi is easily overlooked but belongs to the same pattern as the Aetius/Andrew directives and the Carosus suppression request: Leo is directing the internal governance arrangements of the Constantinopolitan church through the imperial channel. The financial administrators’ accounts are an internal church matter; Leo insists they remain under priestly examination rather than civil jurisdiction. The care extends to every dimension of the church’s life — doctrinal, canonical, disciplinary, calendrical, and now financial.
