Peter said, Youre the Christ, the Son of the living God. Jesus said, Blessed are you. Then strictly charged them to tell no one. Why? Peter knew that Jesus was the Christ, but didnt know what that meant. Peter believed the evil ones lie that the Christ wouldnt suffer for His enemies to redeem His enemies through us. Peter went from Pope to messenger of satan in two verses. Until we see Jesus crucified for the sins of the whole world, it might be best not to tell.
