So, if context dictates everything (at least as you imply the context to be) and it applies to everyone, does everyone have the authority to make judgements binding on the Church? If two people in Chicago make a decision, then two people in Atlanta make a decision the complete opposite, what is truth?
Yes context. Not everything, the text is about judgement in respect to forgiveness when a trespass occurs. Verse 15 through 31 are about forgiving and judging.
Verse 20's binding is in respect to the judgment that falls on the one who did not hear you, the two witnesses and then the church body in relation to their trespass. Verse 15's you is in the 2nd person singular and is being spoken generally. Meaning it applies to you, me, anyone. As
Deut 19:15 applies to anyone. in which verse 16 quotes. The church in verse 17 is the assembly, the congregation. It comes from the Greek word Ekklessia which just means assembly, not the head of the church, everyone.
Verse 17 continues in the 2nd person singular in it's use of the pronoun you. So it is as verse 15 it is being used in the general sense. Here in verse 17 the judgment falls and it dictates that the one trespassed against in verse 15 see the trespasser as a heathen and tax collector. Why? Because they did not hear you, the two or three witnesses and the church body. In this context our Savior says truly I say unto you, whatever we bind or loosen on Earth shall be having been bound or loosen in Heaven. THE BOUND AND LOOSENED IN HEAVEN ARE IN THE PERFECT TENSE. MEANING THAT IT HAS OCCURRED ALREADY. In other word regardless of our judgement God has already made the righteous judgement. Verse 20 with 19 show how we are in accord with this judgement that has occurred in Heaven . Wherein it says that the two or three who are gathered together in agreement must be in His name. And if they are there our Lord is in our midst. For it is He that works in us both to will and do His good pleasure. In this truth anything we ask in His name will be done unto them as verse 20 states.
Then after hearing all this Peter continues in the same context of this teaching of forgiveness and judgment and asks a pertinent question. He asks, "Lord, how often shall my brother sin against me, and I forgive him? Until seven times?" And Jesus said to him, I do not say to you, Until seven times, but, Until seventy times seven.
Here is the text we are looking at. This J.P. Greens literal translation. It is my favorite, and we would recommend it to anyone. But I think I spend more of my devotional time in the Textus Receptus.
"But if your brother sins against you, go and reprove him between you and him alone. If he hears you, you have gained your brother. But if he does not hear, take one or two more with you, "so that on the mouth of two" or "three witnesses every word may stand". *
Deut. 19:15 * But if he fails to hear them, tell * it * to the church. And if he also fails to hear the church, let him be to you as the nations and the tax collector. Truly I say to you, Whatever you
bind on the earth shall occur, having been bound in Heaven. And whatever you loose on the earth shall be, having been loosed in Heaven. Again I say to you, If two of you agree on earth as to anything, whatever they shall
ask, it shall be to them from My Father in Heaven. For where two or three are gathered together in My name, there I am in their midst.
Then coming up to Him, Peter said, Lord, how often shall my brother sin against me, and I forgive him? Until seven times? Jesus said to him, I do not say to you, Until seven times, but, Until seventy times seven. For this reason the kingdom of Heaven has been compared to a man, a king, who decided to take account with his slaves. And when he began to reckon, one debtor of ten thousand talents was brought near to him. But he not having * any * to pay, the lord commanded him to be sold, also his wife and children, and all things, as much as he had, even to pay back. Then falling down, the slave bowed the knee to him, saying, Lord, have patience with me, and I will pay all to you. And being filled with pity, the lord of that slave released him and forgave him the loan. But going out, that slave found one of his fellow slaves who owed him a hundred denarii. And seizing him, he choked * him * , saying, Pay me whatever you owe. Then falling down at his feet, his fellow slave begged him, saying, Have patience with me, and I will pay all to you. But he would not, but going away he threw him into prison until he pay back the * amount * owing. But his fellow slaves, seeing the things happening, they were greatly grieved. And coming they reported to their lord all the things happening. Then calling him near, his lord said to him, Wicked slave! I forgave you all that debt, since you begged me. Ought you not also to favor your fellow slave, as I also favored you? And being angry, his lord delivered him up to the tormentors until he pay back all that debt to him. So also My heavenly Father will do to you unless each of you from your hearts forgive his brother their trespasses. "
