Your point was that, since Jesus charged the Apostles not to say anything about what was discussed at Caesarea Philippi, that this was evidence that Peter was not singled out. My point, in response to this, was that this is demonstrably false, as they were all within earshot of the conversation, and therefore all of them, not just Peter, would have to be warned not to discuss the matter to anyone else. Your point simply has no bearing on the issue of Peter's authority, and that's all I was trying to say.
