In Luke we see the key of knowledge is scripture.
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.
In 2 Thessalonians we see that if they dont obey the word they can be locked out of the church.
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.
The Apostles, not just Peter, were given the keys of knowledge which would be what people needed to be saved.
Then in Matthew Jesus told them that He had given them the keys of heaven which was the key of knowledge and told them that if someone didnt obey they should have no company with them or not allow them to associate with Christians.
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.
****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.
