Leo, bishop of Rome, to all the bishops constituted throughout Mauretania Caesariensis, greetings in the Lord.
Chapter I: Illicit Ordinations Through Tumult; Leo’s Solicitude Owed by Divine Institution
Repeated reports brought to Us by travelers, attesting that illicit ordinations have been usurped among you, have compelled Our duty of piety to investigate the truth — in fulfillment of the solicitude which We owe by divine institution to the universal Church.1 We delegated the charge of Our concern to Our brother and fellow priest Potentius, departing from Us, directing him by Our letters to inquire into the truth of those bishops whose election was reported to be culpable, and to disclose everything to Us with a sincere report.
Since he has fully disclosed everything with a faithful account — revealing which of Christ’s peoples throughout Mauretania Caesariensis are under what kind of leaders — We must give expression to the grief of Our heart, which burns for the dangers to the Lord’s flock. We marvel that through the unrest of the times, or the presumption of the ambitious, or popular tumult, the pastoral office and governance of the churches has been conferred on men who are far removed from priestly merit. This does not serve but harms the people, and increases rather than addresses their dangers: since the integrity of leaders is the safety of those entrusted to them, and where obedience is sound, doctrine is wholesome. Authority seized through ambition, though it may not cause offense by its character and conduct, is pernicious by the example of its beginning — and it is difficult for what began badly to end well.
Chapter II: What It Means to Lay Hands Quickly
If in every rank of the Church we must ensure that nothing in the Lord’s house is disorderly or improper, how much more must we strive to avoid error in choosing one who is to be set above all ranks? For if the head lacks what the body requires, the entire order of the household falters. Where is the precept that the holy Apostle Paul, inspired by the Spirit, addressed through Timothy to all of Christ’s priests: Do not be hasty in laying on hands, nor share in the sins of others (1 Tim. 5:22)? To lay hands quickly is to confer priestly honor on untested men before the maturity of age, before the time of examination, before the merit of obedience, before experience in the discipline of the Church. To share in the sins of others is to ordain someone unworthy and thereby become like him. As a sound priestly choice yields good fruit, so choosing an unworthy colleague brings grave loss to the one who made the choice. No canonical prescription may therefore be overlooked; no unlawful honor may be conferred against divine law.
Chapter III: Only Men of One Wife May Be Deacons, Priests, or Bishops
Since the Apostle lays down that a bishop must be the husband of one wife (1 Tim. 3:2), and this rule extends to the condition of the wife herself — so that she must not have been another man’s before her union with one who had no prior wife — who dares to tolerate what constitutes an injury to this great mystery?2 The statutes of the divine law have not left this provision without support: they declare that the priest shall take a virgin as his wife (Levit. 21:13 et 14; Ezech. 44:22), one unknown to another husband’s bed, and whose children need not fear being counted as another man’s. For even in the Old Testament, priests represented in their persons the spiritual marriage of Christ and the Church — since, as the husband is the head of the wife (Eph. 5:23; 1 Cor. 11:3), the Bride of the Word is taught to know Christ alone, who chooses and loves one and joins no other to Himself. If this pattern was observed even in the figures of the old covenant, how much more must we, under the grace of the Gospel and apostolic precept, observe it? Therefore no one who has been married a second time, or whose wife was previously another man’s, may ascend to the order of deacon, priest, or bishop.
Chapter IV: Neophytes and Untested Men Must Not Be Ordained
The Apostle says: Let them first be tested; then let them serve (1 Tim. 3:10) — meaning we must weigh not only the chastity of marriage but also the merit of labors, so that the pastoral office is not entrusted to new converts or those recently drawn from secular life. For through all the ranks of Christian service, a person’s progress through each grade shows whether greater responsibilities may be committed to him. The sanctions of the blessed Fathers3 judged suitable for sacred duties those who had advanced through the grades over time and proved their character, so that the record of their lives testifies to their conduct. If worldly honors demand time and proof of merit before they are granted, how much more carefully must heavenly dignities and the gifts of God be dispensed? We decree that apostolic and canonical decrees be kept in all things: the Church is not to be handed over to those ignorant of legitimate institutions and humility — men who seek not to grow from humble beginnings but to begin from the heights.
Chapter V: Those Ordained Simply from the Laity Are Tolerated; Bigamists Are Not
Since popular enthusiasm or proud ambition has in some cases elevated laymen, men married a second time, or husbands of widows to the pastoral office, the gravity of these cases calls for the purification of such churches by strict judgment, and punishment for those prelates and for those who ordained them. Yet We, surrounded on every side by mercy and truth — for, as the Psalm attests, all the Lord’s ways are mercy and truth — are constrained by the piety of the Apostolic See to temper Our sentence in this way.4 Those who entered second marriages or married widows are excluded by apostolic and legal authority from all priestly service — and especially one who, as has been reported to Us, is the husband of two wives at once, or one said to have taken another after dismissing his first. But We permit those ordained simply from the laity — whose only disqualification is lay origin — to retain their priesthood, provided their wives are irreproachable, without prejudice to the statutes of the Apostolic See and the rules of the blessed Fathers, which forbid any layman from ascending to any rank of the Church without passing through each grade in legitimate order.
Chapter VI: Donatus, Converted from Novatianism, and Maximus, from Donatism
As for Donatus of Salicia, who came over from the Novatians with his congregation, We decree that he may preside over the Lord’s flock, provided he sends to Us a written profession of faith condemning the errors of Novatian and fully confessing Catholic truth. As for Maximus — who was reprehensibly ordained from the laity — if he is no longer a Donatist and is free from schismatic depravity, he is not to be removed from the episcopal dignity he obtained, provided he submits a written profession establishing his Catholic faith.
Chapter VII: Aggarus and Tyberianus, Ordained from Laymen Through Tumult
Concerning Aggarus and Tyberianus, whose case differs from the rest in that fierce tumults and savage seditions attended their ordinations from laymen, We entrust all to your judgment, so that, on the basis of your examination and report to Us, We may know what to decree concerning them.
Chapter VIII: Virgins Violated by Barbarian Force Must Not Compare Themselves to the Undefiled
Those servants of God who lost the integrity of their bodies through barbarian violence will be found the more praiseworthy in their humility if they do not compare themselves to those whose chastity is unimpaired. For although all sin has its root in the will and an unconquered mind remains unpolluted, it is nonetheless less harmful for them to mourn the loss of bodily chastity — which their soul did not lose — than to claim a standing they can no longer rightly maintain.
Chapter IX: Obedience Urged; Severe Penalties for Those Who Ordain Unlawfully
Since our brother and fellow bishop David, whose priesthood and character are proven, has already made known to you in full nearly everything in Potentius’s report, it remains, brothers, that you receive these wholesome admonitions with one accord. Serving not with contention but with unified devotion, observe the divine and apostolic constitutions and allow no violation of the most provident canonical decrees. What We now remit for the sake of certain cases must henceforth follow the ancient rules, lest what We now grant in pious leniency afterward incur a just sentence. We shall be especially and more severely moved against those who, in ordaining bishops, have neglected the statutes of the holy Fathers and have consecrated those they ought to have refused. Accordingly, if any bishops consecrate a priest whose ordination is unlawful, even if they escape immediate loss of their own honor, they shall have no further right of ordination, and shall never again take part in that sacred action which they wrongfully performed in disregard of God’s judgment.
Chapter X: Bishops Must Be Ordained Only in Appropriate Places; The Case of Restitutus
Concerning priestly dignity, We decree that the canonical statutes be observed in all things: bishops are not to be consecrated in villages or minor places where none previously existed. Where congregations are smaller, a priest suffices; episcopal governance must serve the larger cities, lest the priestly office be diminished by excessive multiplication in obscure localities — contrary to the divinely inspired decrees of the holy Fathers. Our brother bishop Restitutus has raised this complaint rightly, requesting that where bishops in such places die, those territories revert to his diocese, since they were once his or adjacent to his, so that a useless diminishment of priestly dignity may be prevented.
Chapter XI: Violated Virgins: A Balanced Judgment
Concerning those consecrated to the holy state of virginity who, as described above, suffered barbarian violence and lost bodily but not spiritual chastity, We decree a balanced judgment: they are neither to be reduced to the rank of widows nor counted among those virgins who have persevered intact. If they maintain the conduct of virginity and the chastity of their minds, they are not to be denied sacramental communion — for it is unjust to reproach them for what violence, not will, took away.
Chapter XII: The Case of Lupicinus Is to Be Heard
We order the case of Bishop Lupicinus to be brought to hearing: to him We restored communion after his repeated appeals, since he appealed to Our judgment and had been unjustly suspended while proceedings were still in progress. Another was rashly ordained over him while he remained alive — which ought not to have occurred before Lupicinus was either present and convicted, or had himself confessed to a sentence that was just — so that the filling of a see believed to be vacant might proceed as ecclesiastical discipline requires.
Chapter XIII: All Ecclesiastical Cases Must Be Reported to the Apostolic See
If any other cases arise concerning the state of the Church and the harmony of the priests, We will that they be examined there under the fear of God, and a full account of all that transpires sent to Us, so that what has been justly and reasonably decided in accordance with ecclesiastical custom may be confirmed also by Our judgment. Given on the fourth day before the Ides of August.5
Footnotes
- ↩ The phrase sollicitudinem quam universis Ecclesiae ex divina institutione dependimus — “the solicitude which We owe by divine institution to the universal Church” — gives the sollicitudo formula its most explicit grounding in this corpus. Dependimus is debt language: the Roman bishop’s solicitude for all the Churches is not a personal disposition but an obligation incurred by divine institution. A variant in the Vercellum Hadrianum manuscript reads impendimus — “which We expend/bestow for the universal Church” — shifting the emphasis from debt to active employment; but either reading presents the solicitude as a formal obligation, not discretionary concern. The same formula appears in Letters V, VI, and X; here it receives its clearest theological grounding.
- ↩ Leo’s word is sacramentum — translated “mystery” because it carries its full theological weight here. The priestly marriage rule is not merely a canonical regulation: it participates in the divine pattern of Christ’s union with the Church. Leo’s argument is that the OT priest who must marry a virgin prefigures Christ the Bridegroom who takes one Bride, the Church; to violate the rule is to disfigure the theological pattern the rule exists to protect.
- ↩ Leo’s phrase beatorum Patrum sanctiones — “the sanctions of the blessed Fathers” — is his consistent term for the canons of the ecumenical and regional councils (Nicaea, Sardica, and others), not for papal decrees. Elsewhere in this letter he uses apostolicae sedis statuta (statutes of the Apostolic See) for papal legislation, and in Chapter V he keeps the two carefully distinct: “without prejudice to the statutes of the Apostolic See and the rules of the blessed Fathers.” Conciliar authority and apostolic authority are both invoked throughout, but never conflated. Leo’s vocabulary is precise: the beatorum Patrum are the Fathers of the councils; the statuta apostolicae sedis are the rulings of Rome.
- ↩ The word cogimur — “We are constrained” or “compelled” — is deliberate and theologically significant. Leo does not say he chooses, in personal mercy, to moderate the sentence: he says the piety of the Apostolic See constrains him to do so. His moderation is not an exercise of personal discretion but an obligation flowing from the nature of his office. The Apostolic See’s own piety is the governing norm to which Leo himself is bound.
- ↩ August 10, without consular year in the text. The letter is generally placed in 445 or 446 on the basis of its relationship to the Mauretanian mission of Potentius, whose report it acknowledges. The dating formula *Dat. iv id. Augusti* — the fourth day before the Ides of August — yields August 10 by inclusive Roman counting. One manuscript tradition reads *iii id.* (August 11), but the majority reading is *iv id.*
