For those struggling with the necessity of confession, or who need to preach about it, here is what the Scriptures and the Church Fathers say about the necessary participation in this Holy Mystery. This was taken from the St. George Church of Prescott website.
Confession of sins is very much a part of Biblical Faith and especially Biblical Christianity, and was closely related to the worship of the True God. From the Old Testament on, it is clear that men should confess their sins, and this practice, though often neglected and denigrated by scoffers, offers real remission of sins from God. This is the Biblical way, and the way of the early Church, as the following quotes and citations will clearly demonstrate. Indeed, any faith which professes to be Biblical or which claims to follow the ways of the early Church, but does not include confession as a part of its teachings is demonstrably outside of the stream of Christian teachings and practice throughout the ages.
In The Old Testament
“he shall confess his sin that he has committed. And he shall make full restitution for his wrong, adding a fifth to it and giving it to him to whom he did the wrong.”
“Those of Israelite descent separated themselves from all foreigners, and they stood and confessed their sins and the guilt of their fathers. While they stood in their places, they read from the book of the law of the LORD their God for a fourth of the day and spent another fourth of the day in confession and worship of the LORD their God.”
“And read out publicly this scroll which we send you, in the house of the LORD, on the feast day and during the days of assembly: ‘Justice is with the LORD, our God; and we today are flushed with shame, we men of Judah and citizens of Jerusalem, that we, with our kings and rulers and priests and prophets, and with our fathers, have sinned in the LORD’S sight and disobeyed him. We have neither heeded the voice of the LORD, our God, nor followed the precepts which the LORD set before us.’”
Required by John the Baptist
John the Baptist, inspired by the Holy Spirit, also required confession of sins for the baptism of repentance.
“Confessing their sins, they were baptized by him in the Jordan River.”
“And there went out unto him all the land of Judaea, and they of Jerusalem, and were all baptized of him in the river of Jordan, confessing their sins.”
In The New Testament Church
“Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous person is powerful and effective.”
“Also many of those who were now believers came, confessing and divulging their practices.”
“Fight the good fight of the faith. Take hold of the eternal life to which you were called when you made your good confession in the presence of many witnesses.”
1 Timothy 6:12
“If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.”
1 John 1:9
And What The Early Church Really Did
The Early Church clearly taught confession of sins, and in Church! Indeed, the following citations clearly show that from the very beginnings of the post-Apostolic Church down to the present day, confession of sins was understood as holy, necessary and effectual for the remission of sins. Those who avoid it must necessarily find themselves outside of Biblical thought on sin, repentance and confession. Note the dates of these documents! Of special significance is their recognition that confession and absolution must be received by a sinner before receiving Holy Communion, for
“whoever . . . eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of profaning the body and blood of the Lord”
(1 Cor. 11:27).
The Didache – The Earliest Christian Catechism (pre-dating some of the canonical writings of the New Testament)
“Confess your sins in church, and do not go up to your prayer with an evil conscience. This is the way of life. . . . On the Lord’s Day gather together, break bread, and give thanks, after confessing your transgressions so that your sacrifice may be pure”
(Didache 4:14, 14:1 [A.D. 70]).
The Letter of Barnabas
“You shall judge righteously. You shall not make a schism, but you shall pacify those that contend by bringing them together. You shall confess your sins. You shall not go to prayer with an evil conscience. This is the way of light”
(Letter of Barnabas 19 [A.D. 74]).
St. Ignatius of Antioch
“For as many as are of God and of Jesus Christ are also with the bishop. And as many as shall, in the exercise of penance, return into the unity of the Church, these, too, shall belong to God, that they may live according to Jesus Christ”
(Letter to the Philadelphians 3 [A.D. 106]).
“For where there is division and wrath, God does not dwell. To all them that repent, the Lord grants forgiveness, if they turn in penitence to the unity of God, and to communion with the bishop”
St. Irenaeus of Lyons
“[The Gnostic disciples of Marcus] have deluded many women. . . . Their consciences have been branded as with a hot iron. Some of these women make a public confession, but others are ashamed to do this, and in silence, as if withdrawing from themselves the hope of the life of God, they either apostatize entirely or hesitate between the two courses”
(Against Heresies 1:22 [A.D. 189]).
Tertullian of Carthage
“[Regarding confession, some] flee from this work as being an exposure of themselves, or they put it off from day to day. I presume they are more mindful of modesty than of salvation, like those who contract a disease in the more shameful parts of the body and shun making themselves known to the physicians; and thus they perish along with their own bashfulness”
(Repentance 10:1 [A.D. 203]).
St. Hippolytus of Rome
“[The bishop conducting the ordination of the new bishop shall pray:] God and Father of our Lord Jesus Christ. . . . Pour forth now that power which comes from you, from your royal Spirit, which you gave to your beloved Son, Jesus Christ, and which he bestowed upon his holy apostles . . . and grant this your servant, whom you have chosen for the episcopate, [the power] to feed your holy flock and to serve without blame as your high priest, ministering night and day to propitiate unceasingly before your face and to offer to you the gifts of your holy Church, and by the Spirit of the high priesthood to have the authority to forgive sins, in accord with your command”
(Apostolic Tradition 3 [A.D. 215]).
Origen of Alexandria
“[A final method of forgiveness], albeit hard and laborious [is] the remission of sins through penance, when the sinner . . . does not shrink from declaring his sin to a priest of the Lord and from seeking medicine, after the manner of him who say, ‘I said, “To the Lord I will accuse myself of my iniquity”’”
(Homilies on Leviticus 2:4 [A.D. 248]).
St. Cyprian of Carthage
“The apostle [Paul] likewise bears witness and says: ‘ . . . Whoever eats the bread or drinks the cup of the Lord unworthily will be guilty of the body and blood of the Lord’ [1 Cor. 11:27]. But [the impenitent] spurn and despise all these warnings; before their sins are expiated, before they have made a confession of their crime, before their conscience has been purged in the ceremony and at the hand of the priest . . . they do violence to [the Lord’s] body and blood, and with their hands and mouth they sin against the Lord more than when they denied him”
(The Lapsed 15:1–3 (A.D. 251]).
“Of how much greater faith and salutary fear are they who . . . confess their sins to the priests of God in a straightforward manner and in sorrow, making an open declaration of conscience. . . . I beseech you, brethren, let everyone who has sinned confess his sin while he is still in this world, while his confession is still admissible, while the satisfaction and remission made through the priests are still pleasing before the Lord”
“[S]inners may do penance for a set time, and according to the rules of discipline come to public confession, and by imposition of the hand of the bishop and clergy receive the right of Communion. [But now some] with their time [of penance] still unfulfilled . . . they are admitted to Communion, and their name is presented; and while the penitence is not yet performed, confession is not yet made, the hands of the bishop and clergy are not yet laid upon them, the Eucharist is given to them; although it is written, ‘Whosoever shall eat the bread and drink the cup of the Lord unworthily, shall be guilty of the body and blood of the Lord’ [1 Cor. 11:27]“
(Letters 9:2 [A.D. 253]).
“And do not think, dearest brother, that either the courage of the brethren will be lessened, or that martyrdoms will fail for this cause, that penance is relaxed to the lapsed, and that the hope of peace [i.e., absolution] is offered to the penitent. . . . For to adulterers even a time of repentance is granted by us, and peace is given”
“But I wonder that some are so obstinate as to think that repentance is not to be granted to the lapsed, or to suppose that pardon is to be denied to the penitent, when it is written, ‘Remember whence thou art fallen, and repent, and do the first works’ [Rev. 2:5], which certainly is said to him who evidently has fallen, and whom the Lord exhorts to rise up again by his deeds [of penance], because it is written, ‘Alms deliver from death’ [Tob. 12:9]“
St. Aphraahat the Persian Sage
“You [priests], then, who are disciples of our illustrious physician [Christ], you ought not deny a curative to those in need of healing. And if anyone uncovers his wound before you, give him the remedy of repentance. And he that is ashamed to make known his weakness, encourage him so that he will not hide it from you. And when he has revealed it to you, do not make it public, lest because of it the innocent might be reckoned as guilty by our enemies and by those who hate us”
(Treatises 7:3 [A.D. 340]).
St. Basil the Great
“It is necessary to confess our sins to those to whom the dispensation of God’s mysteries is entrusted. Those doing penance of old are found to have done it before the saints. It is written in the Gospel that they confessed their sins to John the Baptist [Matt. 3:6], but in Acts [19:18] they confessed to the apostles”
(Rules Briefly Treated 288 [A.D. 374]).
St. John Chrysostom
“Priests have received a power which God has given neither to angels nor to archangels. It was said to them: ‘Whatsoever you shall bind on earth shall be bound in heaven; and whatsoever you shall loose, shall be loosed.’ Temporal rulers have indeed the power of binding; but they can only bind the body. Priests, in contrast, can bind with a bond which pertains to the soul itself and transcends the very heavens. Did [God] not give them all the powers of heaven? ‘Whose sins you shall forgive,’ he says, ‘they are forgiven them; whose sins you shall retain, they are retained.’ What greater power is there than this? The Father has given all judgment to the Son. And now I see the Son placing all this power in the hands of men [Matt. 10:40; John 20:21–23]. They are raised to this dignity as if they were already gathered up to heaven”
(The Priesthood 3:5 [A.D. 387]).
St. Ambrose of Milan
“For those to whom [the right of binding and loosing] has been given, it is plain that either both are allowed, or it is clear that neither is allowed. Both are allowed to the Church, neither is allowed to heresy. For this right has been granted to priests only”
(Penance 1:1 [A.D. 388]).
St. Jerome of Stridonium
“If the serpent, the devil, bites someone secretly, he infects that person with the venom of sin. And if the one who has been bitten keeps silence and does not do penance, and does not want to confess his wound . . . then his brother and his master, who have the word [of absolution] that will cure him, cannot very well assist him”
(Commentary on Ecclesiastes 10:11 [A.D. 388]).
St. Augustine of Hippo
“When you shall have been baptized, keep to a good life in the commandments of God so that you may preserve your baptism to the very end. I do not tell you that you will live here without sin, but they are venial sins which this life is never without. Baptism was instituted for all sins. For light sins, without which we cannot live, prayer was instituted. . . . But do not commit those sins on account of which you would have to be separated from the body of Christ. Perish the thought! For those whom you see doing penance have committed crimes, either adultery or some other enormities. That is why they are doing penance. If their sins were light, daily prayer would suffice to blot them out. . . . In the Church, therefore, there are three ways in which sins are forgiven: in baptisms, in prayer, and in the greater humility of penance”
(Sermon to Catechumens on the Creed 7:15, 8:16 [A.D. 395]).
