Leo, Bishop of Rome, to Theodore, Bishop of Forum Julii.

I. He should have consulted his metropolitan first

Your first course of action, when troubled by this question, should have been to consult your metropolitan. If he too was unable to assist you, beloved, then both of you should have sought instruction from us together. For in matters that concern all the Lord's priests as a body, no inquiry should be made without the primates. But so that your doubts may in any case be resolved, I will not withhold the Church's rules concerning the state of penitents.

II. The grace of penitence is available to those who fall after baptism

The manifold mercy of God so assists those who fall that not only through the grace of baptism but also through the remedy of penitence the hope of eternal life may be restored. Those who have violated the gifts of their second birth may, by condemning themselves through their own judgment, attain the remission of their sins. The provisions of divine goodness have been so arranged that God's pardon cannot be obtained without the prayers of priests. For the Mediator between God and humanity, the man Christ Jesus (1 Timothy 2:5), transmitted this authority to those set over the Church: that they should both prescribe a course of penance to those who confess and, when they have been cleansed by salutary correction, admit them through the door of reconciliation to communion in the sacraments. In this work the Savior Himself takes an unceasing part, never absent from those things whose execution He has committed to His ministers, saying: "Behold, I am with you always, even to the end of the age" (Matthew 28:20). Whatever is accomplished through our ministry in due order and with good results, we do not doubt has been granted through the Holy Spirit.

III. Penitence is certain only in this life

But if anyone among those for whom we intercede with God is prevented by some obstacle and loses the benefit of immediate repentance, being overtaken by death before reaching the appointed remedy, he cannot receive what was not given to him while he was still living. It is not for us to measure what God alone may weigh and judge. The Lord knows the hearts of all and will deal with each case according to His own inscrutable justice. But this we can say: no one should presume upon God's mercy to the point of delaying repentance, for what is certain in this life becomes uncertain at the moment of death. It is a grave risk to defer the soul's healing to a time that may never come.

IV. Practical guidance on the administration of penance

The duration and form of penance must be determined by the bishop, who shall consider both the gravity of the sin and the sincerity of the penitent's contrition. The ancient practice of the Church prescribes that reconciliation be granted on Holy Thursday -- that is, the Thursday before Easter -- except in cases of urgent danger of death, when the remedy must be provided at whatever time the need arises.

No one who truly repents is to be denied mercy, for God "does not desire the death of the sinner, but that he should turn from his wickedness and live" (Ezekiel 33:11). But neither should reconciliation be granted carelessly or hastily, lest the discipline of the Church be undermined and others be encouraged to sin by the ease of forgiveness.

These rules, which have been handed down by our fathers and confirmed by the authority of the Apostolic See, we commend to your careful observance.
