Leo, Bishop of Rome, to all bishops serving in Campania, Picenum, Etruria, and the surrounding provinces: greetings in the Lord.

The peaceful order of the churches is a great joy to us — and it troubles us deeply whenever we learn that anything has been done in violation of canon law and church discipline. If we fail to address such things with the vigilance our office demands, we cannot stand before the One who set us as watchmen (Ezekiel 3:17) and claim we were not responsible for allowing the Lord's body — which we are bound to keep unstained — to be corrupted by unworthy men. Negligence of this kind damages the whole.

On the ordination of slaves and tenant farmers

It has become common practice to ordain men who have no distinction of birth or character. Some have not even been freed by their masters before being raised to the priesthood, as if servile status were no obstacle to such an honor — as if a man could be acceptable to God who had not yet earned his own master's approval. The problem is twofold: the sacred ministry is degraded by unfit candidates, and the rights of owners are violated when their property is effectively seized without consent. Therefore, dear brothers: all priests in your province are to refuse ordination to such men — and not only to them, but to anyone bound by obligations of birth or service, unless the explicit request or consent of those who hold lawful authority over them has been obtained. A man entering divine service must be free of all other obligations, so that no competing duty can pull him away from the Lord's work.

On men who have been married more than once or who married widows

Once a man's background and conduct have been properly examined, the question of who is fit to serve at the Sacred Altar is settled by the Apostle's teaching, by divine precept, and by the regulations of the canons — from all of which, we find, many of our brothers have widely strayed. Husbands of widows have been admitted to the priesthood. Men who have been married more than once and led dissolute lives have been given every accommodation and ordained to Holy Orders — in direct violation of the blessed Apostle's requirement that a bishop be "the husband of one wife" (1 Timothy 3:2), and contrary to the ancient law's command: "Let the priest take a virgin to wife, not a widow, not a divorced woman" (Leviticus 21:13–14). By the authority of the Apostolic See, we order all such persons removed from their offices and stripped of the priestly title. They can have no claim to a position for which they were never eligible. We consider it particularly our duty to address this, so that existing irregularities can be corrected and future ones prevented, and so that no one can plead ignorance — though it has never been acceptable for a priest to be ignorant of what the canons require. We are sending this letter through our brothers and fellow bishops Innocent, Legitimus, and Segetius, so that whatever has grown up wrongly may be torn out at the root, and no weeds spoil the Lord's harvest. Once the blight is cleared away, what is genuine will bear fruit in abundance.

On usury

We must not pass over this either: certain persons, driven by the love of dirty profit, lend their money at interest and pursue enrichment as usurers. We are grieved to find this practiced not only by clergy but by laypeople who call themselves Christians. Those convicted of this practice are to be sharply punished, so that every occasion for sin is removed.

On acting through another's name

One further warning: no cleric should attempt to make money through another person's name any more than through his own. It is unbecoming to hide wrongdoing behind another man's transactions. The only interest worth seeking is what comes from mercy shown here on earth — knowing the Lord will restore a thousandfold what endures forever.

On compliance

This directive makes clear: if any of our brothers attempts to contravene these rules and dares to do what is forbidden, he must know that he is liable to deposition, and that anyone who refuses to share in our discipline will have no share in our communion. And so that nothing is left unclear, we charge you, beloved, to observe all the decretal rules of our predecessor Innocent of blessed memory, and of all our other predecessors, regarding the orders of the Church and the discipline of the canons. If anyone violates them, let him know all indulgence is denied him.

Dated the 10th of October, in the consulship of Maximus (for the second time) and Paterius (AD 443).
