Letter CLXXI, dated August 18, 460, is the final letter in the Alexandrian correspondence series — the last of more than two dozen letters written by Leo in response to the crisis that began with the murder of Proterius during Holy Week 457. It is addressed to Timothy Salofaciolus, the newly elected orthodox Catholic Bishop of Alexandria, whose installation represents the achievement of everything Leo’s three-year campaign had sought. The letter is warm, brief, and structurally precise — a new relationship being established on exactly the terms Leo has consistently defined.

Chapter I’s congratulation is carefully grounded in canonical fact. Leo notes that Timothy’s election was accomplished by “the clergy and people and all the faithful” acting through “the instinct of faith” — the standard canonical process Leo has insisted on throughout the corpus, from Letter X’s ruling on the province of Vienne through the Inquiry I response in Letter CLXVII. The election is legitimate because it met the canonical conditions Rome has defined; Leo’s recognition is the confirmation of that legitimacy. The distinction is precise: the Egyptian bishops and people performed the canonical act; Leo confirms that the canonical conditions were met. This is the ordinary and immediate jurisdiction of the Roman pontiff expressed in its most positive form — not correction or direction but ratification of what has been rightly done.

The pastoral instruction of Chapter I is notable in its register. Leo’s consistent firmness in doctrine — visible across dozens of letters that refuse any negotiation on Chalcedon — here gives way to an equally firm pastoralism in implementation. Timothy is to reconcile those who resisted the truth not with blows but with the good shepherd’s method: carrying the strayed sheep back on his own shoulders. The imitatio Christi of the good shepherd is not a softening of Leo’s doctrinal positions but their pastoral expression: the solidity of the Catholic faith that admits no division is the very solidity from which the gentleness of reconciliation flows. The shepherd seeks the lost sheep precisely because the sheepfold is firm.

Chapter II’s direction to write frequently to Leo’s solicitude establishes at once the same reporting relationship Leo had built with every major eastern correspondent across this correspondence. The new bishop of the second see in Christendom is from his first communication being placed within the governed structure of the universal Church: the flow of information from Alexandria to Rome is not a courtesy but an ordinary duty of the episcopal office as Leo understands it. The named carriers — Daniel the presbyter and Timothy the deacon — confirm that the relationship is already operational; Timothy has already written to Leo through these men, and Leo is directing that this continue. The Alexandrian correspondence does not end with the resolution of the crisis; it becomes the regular communication of a bishop in communion with the Apostolic See reporting as he is directed to do.

The arc from Letter CXLV to Letter CLXXI — from Leo’s first tentative approach to an untested emperor about a newly murdered bishop to this warm recognition of the man duly elected to replace the usurper — is the fullest demonstration in the Leonine corpus of what the ordinary and immediate jurisdiction of the Roman pontiff looks like when exercised over a sustained crisis. It was not exercised through a council. It was not exercised through conciliar consensus or patriarchal agreement. It was exercised through sustained, coordinated, patient governance — through letters to emperors and patriarchs and vicars and legates and bishops and exiles — until the result the Apostolic See had defined as the only acceptable one was achieved. And then a warm letter to the man installed to occupy the see, directing him to write frequently. The solicitude never stops; it simply turns to the next obligation the office imposes.
