What do YOU think this means?
Why are you calling these words of Christ, the slimmest of reeds?
Are you claiming for yourself infallible interpretation of Scripture?
I think I'll throw this in to the mix......
Here's the context of the passage in question....
Matthew 18:1-3 At that time the disciples came to Jesus, saying, Who is the greatest in the kingdom of heaven? 2 And calling to him a child, he put him in the midst of them and said,.....
Now drop down to the passage in question.
Matthew 18:15-20 If your brother sins against you, go and tell him his fault, between you and him alone. If he listens to you, you have gained your brother. But if he does not listen, take one or two others along with you, that every charge may be established by the evidence of two or three witnesses.
If he refuses to listen to them, tell it to the church. And if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector.
Truly, I say to you, whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven. Again I say to you, if two of you agree on earth about anything they ask, it will be done for them by my Father in heaven. For where two or three are gathered in my name, there am I among them.
OK, context here is that Jesus is talking about disputes between Christians (brothers) and that if one brother has something against another, he is to go and try to be reconciled. This is nothing about going to a priest to make confession, especially as the Catholic church teaches it.
So if someone offends me, I go to them to be reconciled. If we are, there is forgiveness and we agree on it and it is bound in the spiritual realm (heaven if you will). That settles the issue there and effectively closes the case. I think what happens is because it's settled, Satan can no longer access it for us in spiritual attack against either party.
The context indicates that it can be any believer because it's got to do with the parties involved. It does NOT say that we are to confess our sins to a priest to be absolved.
That's exactly it as Paul confirms here...We can always find the truth by comparing scripture with scripture...
2Co 2:10 To whom ye forgive any thing, I forgive also: for if I forgave any thing, to whom I forgave it, for your sakes forgave I it in the person of Christ;
2Co 2:11 Lest Satan should get an advantage of us: for we are not ignorant of his devices.
Regardless of what stage the offense gets forgiven, it is already forgiven by Jesus...Paul as an apostle has already forgiven it...The elders of the church have forgiven it...It is bound in heaven...
Catholics can not discuss bound and loosed in heaven other than to 'claim it' since they don't have a clue what it really means...
