Leo, Bishop of the City of Rome, to all the bishops of Mauritania Caesariensis in Africa: greetings in the Lord.

I. The disorderly appointment of bishops in the province is reprehensible

Frequent reports from visitors to Rome have brought to our attention certain unlawful practices concerning the ordination of bishops among you. The demands of our faith required that we ascertain the true state of affairs, in keeping with the responsibility that by divine command we bear for the whole Church. We therefore entrusted this investigation to our brother and fellow bishop Potentius, who was departing from us, instructing him -- as we communicated to you in writing through him -- to inquire into the facts concerning those bishops whose elections were said to be irregular, and to report everything faithfully to us.

Now that Potentius has disclosed the full picture, making clear to us by his truthful account what manner of leaders govern some of Christ's congregations in certain parts of the province of Mauritania Caesariensis, we have found it necessary to lay bare the grief that weighs upon our hearts for the safety of the Lord's flocks by sending you this letter as well, beloved. We are astonished that either the overbearing conduct of schemers or the rioting of the people could have carried such weight with you during a time of disorder that the chief pastorate and governance of the Church was handed over to the most unworthy persons -- men farthest removed from the priestly standard. This does not serve the people's interests; it harms them. This does not enforce discipline; it deepens division. The integrity of the leaders is the safeguard of those they govern, and where there is willing obedience, sound doctrine follows. But an appointment that has been secured by sedition or seized by intrigue -- even if the man himself does not offend in morals or conduct -- is pernicious from the very example of its beginning. It is hard for things to reach a good end when they were begun in the wrong way.

II. Bishops should never be ordained in haste

If great care and discernment must be exercised in every grade of the Church, so that nothing disorderly or out of place exists in the house of the Lord, how much more carefully must we guard against error in the election of the one who is set over all the other grades? The peace and order of the Lord's entire household is shaken when what is required in the body is not found in the head.

Consider the blessed Apostle Paul's precept, spoken through the Spirit of God, whereby he instructs every generation of Christ's priests through the person of Timothy: "Do not lay hands on anyone hastily, and do not share in other people's sins" (1 Timothy 5:22). What does it mean to "lay hands hastily" if not to confer the priestly office on untested men -- before the proper age, before there has been time to examine them, before they have earned it by their obedience, before they have been tried by discipline? And what does it mean to "share in other people's sins" if not that the one who ordains becomes as culpable as the one who should never have been ordained by him? For just as a man stores up the fruit of his good work when he exercises right judgment in choosing a priest, so one who admits an unworthy man into the ranks of his colleagues brings grievous loss upon himself. We must not set aside in anyone's case what is prescribed by the general ordinances, nor may any advancement be considered lawful that has been made in violation of God's law.

III. The apostolic precept concerning clerical marriage, grounded in Christ's marriage to the Church

As the Apostle says, among the other requirements for election, a bishop must be known to have been "the husband of one wife" (1 Timothy 3:2) -- and this rule was always observed with such reverence that the same standard was understood to apply to those who were to be chosen for priestly office. A man who has married more than once, or who has married a widow, has not satisfied this requirement, nor can any excuse or dispensation override this prohibition.

IV. The canons that must be observed in appointing a bishop

For these reasons, beloved brothers, we require that the following principles be observed in the ordination of bishops throughout your province: No one shall be ordained bishop who has not risen through the established ranks of the clerical order. No one shall be consecrated to lead the people who is unknown to those very people or who has not been requested by them. The consent of the clergy, the testimony of the laity, and the approval of the provincial bishops and the metropolitan must all converge. No one shall be imposed upon a community against its will. Otherwise, a people that has been treated with contempt will come to hate and despise a bishop it did not choose, and it will stray in a direction far worse than it would have taken, on the ground that it was denied the one it wanted.

V. Those who have been irregularly ordained are, for peace's sake, to be tolerated, but with restrictions

Since we seek the peace and welfare of all Christ's churches, we are reluctant to be so strict that we ignore any possibility of mercy. Therefore, those who have already been ordained -- however irregular the circumstances of their appointment -- shall be permitted to retain their sees, provided they have not made their positions still worse by additional offenses. But for the future, let the rules we have laid down be kept in their entirety. If anyone violates them, let him know that he will be deprived of his office and will lose the communion of the Apostolic See.

Let this letter be read to all the brethren, so that ignorance may no longer serve as anyone's excuse.
