In Matthew 16:19, Jesus is specifically addressing Peter. We see in the book of Acts, Peter leads in the opening of doors to three different groups of people so they can enter the Kingdom.
This shows that different Apostles evidently had different roles--- James, the head of the Church in Jerusalem, convened the Council and formulated its decrees; Peter, who received the actual vision from Heaven, taught it and confirmed the brethren.
So Peter was "opening a door" here. But the power of the Keys also includes the power to "shut" the door.
That happened when Pete excommunicated that major troublemaker Simon Magus.
Actually Peter was a part of the problem and one of the factors in the Jerusalem Council being called ... That vision was to CORRECT HIM ...
Yes you can. You can answer my questions. Why did Jesus give Peter the keys to the Kingdom of Heaven? What are these keys exactly? Are they gold? Are there more than one set? Is Peter the only person Jesus gave these keys to? Catholics really turn to these verses right here a lot and I thought you would have some insight on the keys.
