In every instance, the Bible speaks of confessing our sins to the Lord, or
the person one has sinned against, directly to receive forgiveness. No where
does the Bible teach confession of sins to a priest, or intercessionary
Leviticus 5:5 "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:"
Hosea 5:15 "I will go and return to my place, till they acknowledge their offence, and seek my face: in their affliction they will seek me early."
Ezra 10:11 "Now therefore make confession unto the LORD God...."
Psalms 32:5 "I acknowledged my sin unto thee, and mine iniquity have I not hid. I said, I will confess my transgressions unto the LORD; and thou forgavest the iniquity of my sin."
Mark 2:7 " Why doth this man thus speak blasphemies? who can forgive sins but God only?"
1John 1:9 "If we confess our sins, [To God, not a priest] He is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness."
I John 2:1 "And if any man sin, we have an advocate with the Father, Jesus Christ the righteous...."
James 5:16 "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
1 John 1:7-10 "But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin. If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. If we say that we have not sinned, we make him a liar, and his word is not in us."
Some Church's misinterprets the following scriptures,
Matthew 16:19 "And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven."
Matthew 18:15-19 "Moreover if thy brother shall trespass against thee, go and tell him his fault between thee and him alone: if he shall hear thee, thou hast gained thy brother.
But if he will not hear thee, then take with thee one or two more, that in the mouth of two or three witnesses every word may be established.
And if he shall neglect to hear them, tell it unto the church: but if he neglect to hear the church, let him be unto thee as an heathen man and a publican.
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.
Again I say unto you, That if two of you shall agree on earth as touching any thing that they shall ask, it shall be done for them of my Father which is in heaven."
John 20:23 "Whose soever sins ye remit, they are remitted unto them; and whose soever sins ye retain, they are retained."
The "keys of the kingdom" refers to the authority to proclaim the terms of salvation
thru Christ, and the authority to bind or loose is referring to the granting of
forgiveness to those that believe in the the proclamation of the gospel, or bondage
to the sin penalty for those who reject it. It has nothing to do with granting
forgiveness of sins by a priest.
