****Luke 11:52 Woe unto you, lawyers! for ye have taken away the key of knowledge: ye entered not in yourselves, and them that were entering in ye hindered.****
You will have to explain your understanding of that passage more fully because nowhere in it do I see where Jesus says that Scripture is the key to the kingdom.
****2 Thessalonians 3:14 And if any man obey not our word by this epistle, note that man, and have no company with him, that he may be ashamed.*****
Excommunication from the Church. Which again does not say that the Scriptures are the keys to the kingdom.
****The Apostles, not just Peter, were given the “keys of knowledge” which would be what people needed to be saved.****
Scripture says they were given the keys to the kingdom of heaven, not knowledge. And no one has said that Peter served as a dictator, he was the leader as the rock, not the tyrant.
I would like you to present from Scripture where the key of knowledge is equated to the keys to the kingdom and where it is said that Scripture is the key to the kingdom.
Otherwise, what you have done is read into what you have posted an implicit understanding of what is not explicit in Scripture.
Start with knowledge opens doors right? With the right knowledge you can become a lawyer or whatever. Knowledge will help you get into places while lack of knowledge will lock you out. The keys to that knowledge are books, writings and teaching.
In Old Testament times when the Jews made a mad a doctor of the law he received the key to the closet in the temple where they kept the sacred books and the tablets to write on. Those books contained the laws of the Jews. Thus the reference in Luke.
Luke 11:52 Woe unto you, lawyers! for ye have taken away the key of knowledge: ye entered not in yourselves, and them that were entering in ye hindered.
They were keeping the information that God had commanded away from the people and were only teaching the portions of the law they found benefited the elite and helped them maintain superiority over the people. A reference to that can be found in Matthew 23 when Jesus accused them of doing the external things but not teaching the spiritual truths.
The binding and loosing also comes from Jewish customs. The priests could declare a person unfit for fellowship with the people. If the person was not following the laws of God they could be “bound” or kept out of the gatherings. They also considered that what they “bound” on earth was also “bound” in heaven because they were the keepers of the law that God had given them. That’s the context of the verse in 2 Thessalonians.
2 Thessalonians: 3:14 And if any man obey not our word by this epistle, note that man, and have no company with him, that he may be ashamed.
Christ had given all the information or “knowledge” for New Testament believers to the Apostles thus the statement in Matthew.
Matthew 18:18 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.
The Apostles had been taught the New Testament teachings of grace and forgiveness that gave the people life eternal in heaven. That information was considered the “key” to heaven. The Apostles had been given that “key” and just like the Old Testament Jewish “lawyer” they were empowered to teach those and could declare someone who didn’t believe or taught falsely “bound” and not fit for fellowship with believers. That person would also be considered “bound” in heaven also.
