Jesus Requires YOU To Confess YOUR Sins To Him

Jesus Requires YOU To Confess YOUR Sins To Him, And Confess To Others That Jesus Is YOUR Lord.
In the Levitical Law referenced in the Holy Word of God, the High Priest was required to offer blood sacrifices as an atonement for man's sins, and confess man's sins to God.
Leviticus 5:5-6  "'When anyone is guilty in any of these ways, he must confess in what way he has sinned 6 and, as a penalty for the sin he has committed, he must bring to the LORD a female lamb or goat from the flock as a sin offering; and the priest shall make atonement for him for his sin.
Leviticus 16:20-21  "When Aaron has finished making atonement for the Most Holy Place, the Tent of Meeting and the altar, he shall bring forward the live goat. 21 He is to lay both hands on the head of the live goat and confess over it all the wickedness and rebellion of the Israelites--all their sins--and put them on the goat's head. He shall send the goat away into the desert in the care of a man appointed for the task.
On the Day of Atonement, when the High Priest went into the Most Holy Place, he was a fore-glimpse of Jesus Christ, the true High Priest and intercessor who sits at the right hand of God the Father.
Hebrews 9:1-14 Now the first covenant had regulations for worship and also an earthly sanctuary. 2 A tabernacle was set up. In its first room were the lampstand, the table and the consecrated bread; this was called the Holy Place. 3 Behind the second curtain was a room called the Most Holy Place, 4 which had the golden altar of incense and the gold-covered ark of the covenant. This ark contained the gold jar of manna, Aaron's staff that had budded, and the stone tablets of the covenant. 5 Above the ark were the cherubim of the Glory, overshadowing the atonement cover. But we cannot discuss these things in detail now. 6 When everything had been arranged like this, the priests entered regularly into the outer room to carry on their ministry. 7 But only the high priest entered the inner room, and that only once a year, and never without blood, which he offered for himself and for the sins the people had committed in ignorance. 8 The Holy Spirit was showing by this that the way into the Most Holy Place had not yet been disclosed as long as the first tabernacle was still standing. 9 This is an illustration for the present time, indicating that the gifts and sacrifices being offered were not able to clear the conscience of the worshiper. 10 They are only a matter of food and drink and various ceremonial washings--external regulations applying until the time of the new order. 11 When Christ came as high priest of the good things that are already here, he went through the greater and more perfect tabernacle that is not man-made, that is to say, not a part of this creation. 12 He did not enter by means of the blood of goats and calves; but he entered the Most Holy Place once for all by his own blood, having obtained eternal redemption. 13 The blood of goats and bulls and the ashes of a heifer sprinkled on those who are ceremonially unclean sanctify them so that they are outwardly clean. 14 How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God!
Hebrews 6:19-20 We have this hope as an anchor for the soul, firm and secure. It enters the inner sanctuary behind the curtain, 20 where Jesus, who went before us, has entered on our behalf. He has become a high priest forever, in the order of Melchizedek.
At the very moment when Jesus died, the veil of the Temple dividing common man from the Most Holy Place was torn in two "from top to bottom." The fact that the veil was torn beginning at the top revealed that God, not man had torn the veil.
Mark 15:37-38  With a loud cry, Jesus breathed his last. 38 The curtain of the temple was torn in two from top to bottom.
This was a declaration by God, that YOU are now allowed into the Most Holy Place through the Blood of Jesus Christ for YOUR own personal individual confession.
Hebrews 10:19-22  Therefore, brothers, since we have confidence to enter the Most Holy Place by the blood of Jesus, 20 by a new and living way opened for us through the curtain, that is, his body, 21 and since we have a great priest over the house of God, 22 let us draw near to God with a sincere heart in full assurance of faith, having our hearts sprinkled to cleanse us from a guilty conscience and having our bodies washed with pure water.

1 John 1:9  If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.
Proverbs 28:13 He who conceals his sins does not prosper, but whoever confesses and renounces them finds mercy.
Confession of YOUR sins to God is a requirement of salvation, as well as confession that Jesus Christ is YOUR God.
Romans 10:9-10 That if you confess with your mouth, "Jesus is Lord," and believe in your heart that God raised him from the dead, you will be saved. 10 For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved.
2 Timothy 2:19  Nevertheless, God's solid foundation stands firm, sealed with this inscription: "The Lord knows those who are his," and, "Everyone who confesses the name of the Lord must turn away from wickedness."
2 Corinthians 9:13  Because of the service by which you have proved yourselves, men will praise God for the obedience that accompanies your confession of the gospel of Christ, and for your generosity in sharing with them and with everyone else.

Can Christian be perfect without sin?

1.Christians can live perfect:

Without Christ by our own human efforts we can not be perfect. The Christian whose faith is in the blood of Jesus Christ knows that faith makes us right with God.

Christians are perfect only through the one sacrifice that Jesus made. God is perfect without sin; God expects them also to be perfect without sin. Jesus' sinless life gives us a perfect example to follow.

Scripture on perfection:

"Because by one sacrifice he has MADE PERFECT FOREVER those who are being made holy." Hebrews 10:14

Matt 5:48 Be ye therefore perfect, even as your Father which is in heaven is perfect."

Noah was perfect because Noah had not disobeyed a single commandment given to him by God. "Gen 6:9 - Noah was a just man and perfect in his generations, and Noah walked with God. 22 Thus did Noah; according to all that God commanded him, so did he."

God himself challenged the devil saying that Job lived a perfect life. "Job 1:8 And the LORD said unto Satan, Hast thou considered my servant Job, that there is none like him in the earth, a perfect and an upright man, one that feareth God, and escheweth evil?" The Word of God says that Job has not committed sin. "Job1:22 In all this Job sinned not,”

God told Abraham to live a perfect life before him. "Gen 17:1 And when Abram was ninety years old and nine, the LORD appeared to Abram, and said unto him, I am the Almighty God; walk before me, and be thou perfect". Abraham fulfilled what God has required of him and received the testimony even from Jesus Christ. "John 8:39 They answered and said unto him, Abraham is our father. Jesus saith unto them, If ye were Abraham's children, ye would do the works of Abraham."

When King Hezekiah was sick he asked God to remember his perfect life and God favored him immediately. "2 King 20:3 I beseech thee, O LORD, remember now how I have walked before thee in truth and with a perfect heart, and have done that which is good in thy sight."

Phil 3:15 Let us therefore, as many as be perfect, be thus minded: and if in any thing ye be otherwise minded, God shall reveal even this unto you."

1 Cor 2:6 Howbeit we speak wisdom among them that are perfect: yet not the wisdom of this world, nor of the princes of this world,---."

Eph 4:11 And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers; 12 For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ: 13 Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ:."

Col 1:28 Whom we preach, warning every man, and teaching every man in all wisdom; that we may present every man perfect in Christ Jesus: 29 Whereunto I also labour, striving according to his working, which worketh in me mightily."

1 Pet 5:10 But the God of all grace, who hath called us unto his eternal glory by Christ Jesus, after that ye have suffered a while, make you perfect, stablish, strengthen, settle you."

Aim for perfection, listen to my appeal, be of one mind, live in peace. And the God of love and peace will be with you. 2 Corinthians 13:11

Christians can live without sin:

We can live our life free from sin through Christ who strengthens us because we have been set free from sin by the Spirit of God and we are no longer slaves to sin.

No one who is born of God will continue to sin, because God's seed remains in him; he cannot go on sinning, because he has been born of God. 1 John 3:9

We know that anyone born of God does not continue to sin; the one who was born of God keeps him safe, and the evil one cannot harm him. 1 John 5:18

To him who is able to keep you from falling and to present you before his glorious presence without fault and with great joy to the only God our Savior be glory, majesty, power and authority, through Jesus Christ our Lord, before all ages, now and forevermore! Amen. Jude 24, 25

Being then made free from sin, ye became the servants of righteousness… But now being made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life. — Rom 6:18, 22

WHY DO I HAVE TO CONFESS MY SINS TO A PRIEST?

Any forgiving I have done has been for your sakes, and, before Christ, to prevent Satan -- whose guile we know too well -- from outwitting us."(2 Corinthians 2:10-11)
We confess our sins to a priest simply because Jesus said so. He gave the apostles authority to forgive sins in His name. (Jn 20:23) God, of course, does all the forgiving and all the healing, teaching, counseling, feeding, etc. Everything good is done by God's power, but He often works through people, members of the body of Christ, and He has decided to use people as His instruments in teaching, feeding, counseling, etc., and even in forgiving. We are open to God using a person to feed us but when it comes to forgiveness, we are reluctant to involve other people and think we should talk to God alone. But God commands: "Declare your sins to one another, and pray for one another, that you may find healing." (Jas 5:16)
So, Biblically, we are to confess our sins not only to God but also to other human beings. But why a priest? A priest represents the family of God, our community, the local body of Christ. We confess our sins to a representative of the Christian family because our sins hurt others in the family, and to be reconciled fully we must ask forgiveness not only of God Whom we have disobeyed and those immediately affected by our sins but also of the church family hurt by our sins. It's impossible to apologize to each and every one, but at least we can talk to a representative of the family and ask forgiveness. Unless we confess our sins to a priest, we feel like there's something missing because there is something missing: reconciliation with the church family.

Do the sons bear the sins of the fathers or not?

Yes they do
(Exodus 20:5) - "You shall not worship them or serve them; for I, the Lord your God, am a jealous God, visiting the iniquity of the fathers on the children, on the third and the fourth generations of those who hate Me,"
(Deuteronomy 5:9) - "You shall not worship them or serve them; for I, the Lord your God, am a jealous God, visiting the iniquity of the fathers on the children, and on the third and the fourth generations of those who hate Me,"
(Exodus 34:6-7) - "Then the Lord passed by in front of him and proclaimed, "The Lord, the Lord God, compassionate and gracious, slow to anger, and abounding in lovingkindness and truth; 7who keeps lovingkindness for thousands, who forgives iniquity, transgression and sin; yet He will by no means leave the guilty unpunished, visiting the iniquity of fathers on the children and on the grandchildren to the third and fourth generations."
(1 Cor. 15:22) - "For as in Adam all die, so also in Christ all shall be made alive."
No they don't
(Deuteronomy 24:16) - "Fathers shall not be put to death for their sons, nor shall sons be put to death for their fathers; everyone shall be put to death for his own sin."
(Ezekiel 18:20) - "The person who sins will die. The son will not bear the punishment for the father’s iniquity, nor will the father bear the punishment for the son’s iniquity; the righteousness of the righteous will be upon himself, and the wickedness of the wicked will be upon himself."
Exodus 20:5 is, of course, among the ten commandments. The Ten Commandments are arranged in covenant form. The Suzerain-Vassal treaty pattern of the ancient near east is followed in the Ten Commandments. This arrangement included an introduction of who was making the covenant (Exodus 20:2), what the covenant maker had done (20:2), laws (20:3-17), rewards (20:6,12), and punishments (20:5,7).
Covenantally, when a father misleads his family, the effects of that misleading are often felt for generations. This is because the father is being covenantally unfaithful and God has stipulated that there are punishments to breaking the covenant with God. That is the case with these verses that deal with the sins visited upon the children. If a father rejects the covenant of God and takes his family into sin and rejects God, the children will suffer the consequences, often for several generations. Whether or not this is fair is not the issue. Sin is in the world, consequences of sin affected many generations.
On the other hand, Deuteronomy 24:16 is dealing with legal matters as the context 24:6-19 shows. Ezekiel 18:20 is merely recounting the Law of the Pentateuch. Therefore, the context of the second set of verses is dealing with the legality aspect within the Jewish court system. The previous set of verses deal with God visiting upon the descendents of the rebellious the consequences of the rebellious fathers' sins.
As a further note on this issue, there is a concept in the Bible called Federal Headship. This means that the male, the father, represents the family. We see this in the garden of Adam and Eve. She was the first one to eat of the fruit; she was the first one to sin. However, the Bible states that sin entered the world through Adam (Rom. 5), not Eve. This is because Adam was the Federal Head of all mankind. Furthermore we see in the Hebrews 7:7-10 the following:
"But without any dispute the lesser is blessed by the greater. 8And in this case mortal men receive tithes, but in that case one receives them, of whom it is witnessed that he lives on. 9And, so to speak, through Abraham even Levi, who received tithes, paid tithes, 10for he was still in the loins of his father when Melchizedek met him."
In the verses in Hebrews we see that Levi, who was a descendant of Abraham, paid tithes to Melchizedek while still in the loins, "seed," of his father Abraham, even though Levi was not yet alive. In other words, Abraham, the father, represented his descendants. As Abraham paid tithes, so also did Levi. Therefore, we can see the concept of Federal Headship represented in the Bible in both the Old and New Testaments. We can conclude that God will visit the iniquities of the fathers upon the descendants because the fathers have failed to be covenantally faithful. Yet, we see in the other verses a declaration of legality in dealing with people. There is no contradiction.

Can you be forgiven of all sins or not?

All sins not forgiven
(Matthew 12:31) - "Therefore I say to you, any sin and blasphemy shall be forgiven men, but blasphemy against the Spirit shall not be forgiven."
(Mark 3:29) - "but whoever blasphemes against the Holy Spirit never has forgiveness, but is guilty of an eternal sin. 32And whoever shall speak a word against the Son of Man, it shall be forgiven him; but whoever shall speak against the Holy Spirit, it shall not be forgiven him, either in this age, or in the age to come."
All sins forgiven
(Acts 13:39) - "and through Him everyone who believes is freed from all things, from which you could not be freed through the Law of Moses."
(Titus 2:13-14) - "looking for the blessed hope and the appearing of the glory of our great God and Savior, Christ Jesus; 14who gave Himself for us, that He might redeem us from every lawless deed and purify for Himself a people for His own possession, zealous for good deeds."
(1 John 1:9) - "If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness."
When interpreting the Bible, context is everything. Anyone can take a verse out of context in one place and compare it to another verse out of context in another. Such is often the case when critics quote these types of scriptures listed above as criticism of the Bible.
The answer is simple. We are to take all of God's word into account, in context, when developing a teaching. Therefore, the Bible teaches us that blasphemy against the Holy Spirit is unforgivable. All other sins are forgivable. However, this does not mean that all sins will be forgiven. It means that all these other sins can be forgiven. We are forgiven only when we trust in Christ and Him alone for the forgiveness of our sins. Those who have committed blasphemy of the Holy Spirit will never seek Christ because the Holy Spirit will not work on them

The Bible teaches us to Confess our sins to Priest

As proven using quotations from the 1611 King James version of the Bible, a famous Protestant translation.
Many non-Catholics say that confession to a priest is not taught in the Bible. They say that to be forgiven of even mortal sin, all one need to do is believe in Jesus, or at the most, to confess those sins directly to God. But this position which holds that confession to a priest is not necessary for forgiveness of mortal sins committed after baptism contradicts what is taught in the Bible.


The Old Law required confession of sins to a priestFirst, in the Old Testament, if one committed a sin, he couldn't just confess the sin to God and be done with it. No, he had to go to the priest. This is taught throughout the book of Leviticus, the third book of the Old Testament. Here is one good example of this:
Leviticus 5:1: And if a soul sin, and hear the voice of swearing, and is a witness, whether he hath seen or known of it; if he do not utter it, then he shall bear his iniquity. 2: Or if a soul touch any unclean thing, whether it be a carcase of an unclean beast, or a carcase of unclean cattle, or the carcase of unclean creeping things, and if it be hidden from him; he also shall be unclean, and guilty. 3: Or if he touch the uncleanness of man, whatsoever uncleanness it be that a man shall be defiled withal, and it be hid from him; when he knoweth of it, then he shall be guilty. 4: Or if a soul swear, pronouncing with his lips to do evil, or to do good, whatsoever it be that a man shall pronounce with an oath, and it be hid from him; when he knoweth of it, then he shall be guilty in one of these. 5: And it shall be, when he shall be guilty in one of these things, that he shall confess that he hath sinned in that thing: 6: And he shall bring his trespass offering unto the LORD for his sin which he hath sinned, a female from the flock, a lamb or a kid of the goats, for a sin offering; and the priest shall make an atonement for him concerning his sin. 7: And if he be not able to bring a lamb, then he shall bring for his trespass, which he hath committed, two turtledoves, or two young pigeons, unto the LORD; one for a sin offering, and the other for a burnt offering. 8: And he shall bring them unto the priest, who shall offer that which is for the sin offering first, and wring off his head from his neck, but shall not divide it asunder: 9: And he shall sprinkle of the blood of the sin offering upon the side of the altar; and the rest of the blood shall be wrung out at the bottom of the altar: it is a sin offering. 10: And he shall offer the second for a burnt offering, according to the manner: and the priest shall make an atonement for him for his sin which he hath sinned, and it shall be forgiven him.
In this passage we see that the priest's role was indispensible in the forgiveness of sin. This is taught throughout Leviticus and throughout the other foundational books of the Old Testament. Here is another example:
Leviticus 19:21: And he shall bring his trespass offering unto the LORD, unto the door of the tabernacle of the congregation, even a ram for a trespass offering. 22: And the priest shall make an atonement for him with the ram of the trespass offering before the LORD for his sin which he hath done: and the sin which he hath done shall be forgiven him.
Not only did a person have to go to the priest to be forgiven of sin, as these and other passages make clear, but also to become clean. Jesus makes reference to this in the following verse from the New Tesatment:
Luke 5:13: And he put forth his hand, and touched him, saying, I will: be thou clean. And immediately the leprosy departed from him. 14: And he charged him to tell no man: but go, and shew thyself to the priest, and offer for thy cleansing, according as Moses commanded, for a testimony unto them.
In the Old Testament, people would become unclean after having done certain things which God said made a person unclean. To become clean, the priest would have to be involved.
Leviticus 12:6: And when the days of her purifying are fulfilled, for a son, or for a daughter, she shall bring a lamb of the first year for a burnt offering, and a young pigeon, or a turtledove, for a sin offering, unto the door of the tabernacle of the congregation, unto the priest: 7: Who shall offer it before the LORD, and make an atonement for her; and she shall be cleansed from the issue of her blood. This is the law for her that hath born a male or a female. 8: And if she be not able to bring a lamb, then she shall bring two turtles, or two young pigeons; the one for the burnt offering, and the other for a sin offering: and the priest shall make an atonement for her, and she shall be clean.
Leviticus 13:27: And the priest shall look upon him the seventh day: and if it be spread much abroad in the skin, then the priest shall pronounce him unclean: it is the plague of leprosy.
Leviticus 14:11: And the priest that maketh him clean shall present the man that is to be made clean, and those things, before the LORD, at the door of the tabernacle of the congregation:
Leviticus 14:19: And the priest shall offer the sin offering, and make an atonement for him that is to be cleansed from his uncleanness; and afterward he shall kill the burnt offering: 20: And the priest shall offer the burnt offering and the meat offering upon the altar: and the priest shall make an atonement for him, and he shall be clean.
Leviticus 14:31: Even such as he is able to get, the one for a sin offering, and the other for a burnt offering, with the meat offering: and the priest shall make an atonement for him that is to be cleansed before the LORD.
These points from the Old Testament demonstrate how God works and how He has worked throughout salvation history. God had priests. God set up a priesthood. God forgives and reconciled through priests. People had to go to the priests to be forgiven.
In Numbers 3, we see a reference to a special line of priests, who alone are able to handle this ministry.
Numbers 3:10: And thou shalt appoint Aaron and his sons, and they shall wait on their priest's office: and the stranger that cometh nigh shall be put to death.
Numbers 3:3: also says that priests hands were consecrated, but that has been removed from the Protestant Bible.

We also see a specific reference to the necessity of confession of sin.In Numbers 5:6: Speak unto the children of Israel, When a man or woman shall commit any sin that men commit, to do a trespass against the LORD, and that person be guilty;
7: Then they shall confess their sin which they have done: and he shall recompense his trespass with the principal thereof, and add unto it the fifth part thereof, and give it unto him against whom he hath trespassed.
The rest of the chapter contains instructions, which involve priests at every turn. For example:
Numbers 5:14: And the spirit of jealousy come upon him, and he be jealous of his wife, and she be defiled: or if the spirit of jealousy come upon him, and he be jealous of his wife, and she be not defiled: 15: Then shall the man bring his wife unto the priest, and he shall bring her offering for her, the tenth part of an ephah of barley meal; he shall pour no oil upon it, nor put frankincense thereon; for it is an offering of jealousy, an offering of memorial, bringing iniquity to remembrance. 16: And the priest shall bring her near, and set her before the LORD:
In this verse we see a clear example of confession as well as the intercession of priests. In Numbers 6:11, in the very next chapter we see that if a man becomes defiled by a certain action, “11: And the priest shall offer the one for a sin offering, and the other for a burnt offering, and make an atonement for him,”
In Numbers 15, we again see that sins are forgiven through the priests.
Number 15:22: And if ye have erred, and not observed all these commandments, which the LORD hath spoken unto Moses, 23: Even all that the LORD hath commanded you by the hand of Moses, from the day that the LORD commanded Moses, and henceforward among your generations; 24: Then it shall be, if ought be committed by ignorance without the knowledge of the congregation, that all the congregation shall offer one young bullock for a burnt offering, for a sweet savour unto the LORD, with his meat offering, and his drink offering, according to the manner, and one kid of the goats for a sin offering. 25: And the priest shall make an atonement for all the congregation of the children of Israel, and it shall be forgiven them;
This is also repeated in Number 15:28.
We read also in Exodus about the office of priests and that priests wear special garments.Exodus 28:1: And take thou unto thee Aaron thy brother, and his sons with him, from among the children of Israel, that he may minister unto me in the priest's office, even Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron's sons. 2: And thou shalt make holy garments for Aaron thy brother for glory and for beauty. 3: And thou shalt speak unto all that are wise hearted, whom I have filled with the spirit of wisdom, that they may make Aaron's garments to consecrate him, that he may minister unto me in the priest's office.
We read about this in Leviticus as well.
Leviticus 16:32: And the priest, whom he shall anoint, and whom he shall consecrate to minister in the priest's office in his father's stead, shall make the atonement, and shall put on the linen clothes, even the holy garments:
We also read about special feast days, or holy days of obligation, which were to be observed.
Leviticus 23:4: These are the feasts of the LORD, even holy convocations, which ye shall proclaim in their seasons.
In Deuteronomy 17:9 and 24:8, we also read about the necessity to follow the instructions of the priests. In Deuteronomy 26:1-5, we read about offering the first fruits through the priests. There is no doubt that God established it so that men were forgiven, reconciled and made clean through the ministry of the priests.
That was how God worked in the Old Law, now what about in the New Law?In Matthew 5:17: Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfill. 18: For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
Jesus came not to destroy the Law and the prophets, but to fulfill. There is no doubt that the New Law surpasses the old. It surpasses it so much that it makes it obsolete. Jesus accomplished all the figures and prophesies in the Old Law, and made it perfect, rendering the old thereby void. But the New Law has similarities to the Old Law, being its fulfillment.
For example, in the Old Testament there were twelve tribes with twelve tribal leaders. Likewise, in the New Testament, Jesus has twelve Apostles.
Another example would be how Jesus inherits the throne of David, as we read in Luke 1:32 and Acts 2:30. Jesus and His spiritual kingdom, which is the Church, fulfill what was prefigured in the earthly kingdom of the Davidic monarchy. Another example would be how in the Old Testament a father passed his blessing on to his son through the laying on of hands. In Deuteronomy 34:9 we see that spiritual authority is passed on to Joshua through the laying on of hands. Likewise, in the New Testament priests were ordained through the laying on of hands, as we read in 2 Timonthy 1:6. So the point is that while Jesus’ kingdom and New Law surpass and make void the old, the New Law nevertheless fulfills, perfects and corresponds to the Old Law in many ways. So just as there was definitely a priesthood in the Old Testament, there is a priesthood in the New Testament. The Apostles were made priests and bishops by Jesus Christ, and just as the priests were involved in the process of the covering or forgiveness of sin in the Old Testament, Jesus gave priests the power to forgive sins in the New Testament.
John 20:21: Then said Jesus to them again, Peace be unto you: as my Father hath sent me, even so send I you. 22: And when he had said this, he breathed on them, and saith unto them, Receive ye the Holy Ghost: 23: Whose soever sins ye remit, they are remitted unto them; and whose soever sins ye retain, they are retained.
Jesus says that whose so ever sins the Apostles forgive, they are forgiven, and whose soever sins they retain (do not forgive), they are retained (not forgiven). Nothing could be more clear. The only way the Apostles could be expected to know which sins to forgive and which sins to retain is obviously if they heard a confession of those sins. This passage proves that Jesus instituted confession to priests.
Even though the meaning of the passage is obvious, there is another point that must be noted in this regard.
Matthew 9:6: But that ye may know that the Son of man hath power on earth to forgive sins, (then saith he to the sick of the palsy,) Arise, take up thy bed, and go unto thine house. 7: And he arose, and departed to his house. 8: But when the multitudes saw it, they marvelled, and glorified God, which had given such power unto men.
This passage notes that the Son of Man hath power on earth to forgive sin and the multitudes marvelled how God had given such authority and power to men. Jesus is both God and man, but notice that this passage emphasizes that he had the authority as the Son of Man to forgive sins. Since Jesus had authority to forgive sins as the Son of Man, as is also made clear in Matthew 28, when Jesus says that He has been given all power in heaven and in earth, then He can transfer that authority to forgive sins to others. Look at this verse again:
John 20:21: Then said Jesus to them again, Peace be unto you: as my Father hath sent me, even so send I you.
Just as Jesus was sent as the Son of Man with power on earth to forgive sins, He sends His Apostles to dispense His forgiveness to others. That’s why St. Paul, who was made apriest and bishop in the Church, says this:
2 Corinthians 5:18: And all things are of God, who hath reconciled us to himself by Jesus Christ, and hath given to us the ministry of reconciliation;
19: To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation.
20: Now then we are ambassadors for Christ, as though God did beseech you by us: we pray you in Christ's stead, be ye reconciled to God.
Jesus sends His Apostles to be the ministers of His reconciliation and His forgiveness as this passage makes clear. That is why the Church has taught that priests, in hearing confessions, stand in the place of Christ. They are not a barrier to Christ, but an avenue, a conduit of His reconciliation, just as St. Paul says “we pray you in Christ's stead, be ye reconciled to God”
So that’s why right after sending His Apostles in John 20:21, as His Father has sent Him, Jesus gives them the power to forgive and retain sins. All of this proves without any doubt that Jesus instituted confession to priests for the forgiveness of sins.
As a further demonstration of this fact, we see that the Apostles were given the power to bind and to loose.
Matthew 16:18: Verily I say unto you, Whatsoever ye shall bind on earth shall be bound in heaven: and whatsoever ye shall loose on earth shall be loosed in heaven.
This has application to the forgiveness of sins and to the fact that Jesus dispensed this authority to valid bishops and priests in His one true Church. But this authority must be used under the unique authority of the keys which were given alone to St. Peter in Matthew 16:18-20.
1 John 1:9: If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
Notice that the passage says if we confess our sins He is faithful and just to forgive us our sins. It does not say He will forgive us whether or not we forgive our sins, or so long as we believe. In James 5, we also see a refernce to confessing sins, priests and the forgiveness of sins.
James 5: 14: Is any sick among you? let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord: 15: And the prayer of faith shall save the sick, and the Lord shall raise him up; and if he have committed sins, they shall be forgiven him. 16: Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much.
This passage is a classic proof for the Catholic sacrament of Extreme Unction, a priestly anointing and rite, which, if properly received in danger of death strengthens man in the final combat of life and forgives him his sin.
In this passage if James 5 we read that you should “confess your faults to one another”. That instruction comes directly after making reference to calling for the elders or priests of the Church, showing once again the necessity of confession and priests and the link between the two.
All of this shows that the New Testament teaches that confession to a priest is necessary for serious (mortal) sins committed after baptism. That is why the Catholic Church, the one true Church of Jesus Christ, has taught this for 2000 years.
