Of course, how else can you try to justify the false supremecy of the Pope?
Regardless of who left who, 4 stayed together, and were correct in doing it..
I admit, depending on how you read the keys part, it can look like it was just Peter. But like I aid before, it can't be because that would make the other Apostles invalid and worthless if only Peter had the keys to Heaven..
But the binding and loosing part was to all Apostles, that one you can't read wrong..
15"If your brother sins against you, go and show him his fault, just between the two of you. If he listens to you, you have won your brother over. 16But if he will not listen, take one or two others along, so that 'every matter may be established by the testimony of two or three witnesses.' 17If he refuses to listen to them, tell it to the church; and if he refuses to listen even to the church, treat him as you would a pagan or a tax collector.
18"I tell you the truth, whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.
He is talking to ALL the Apostles in the above quote..so therefore when you read the quote below, you can also see He is talking to ALL of them as well..
18And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it. 19I will give you the keys of the kingdom of heaven; whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven." 20Then he warned his disciples not to tell anyone that he was the Christ.
So obviously if you look at both these verses, you can clearly say He was not talking to ONLY Peter..
Problem with the RCC is they assume the keys are some physical key to a gate. It's not. How does one get into heaven? By following Christ and His teachings, by believing in Him, etc. Therefore these things are the keys that can open the gates of heaven. He gaves these things to ALL the Apostles, not just Peter, or else like I said, the other Apostles would have no authority to teach anyone how to get to heaven.
Keys=metaphor for a way to enter, or unlock a mystery...mystery would be how to attain salvation. ALL the Apostles taught us this mystery...
