Those who preach that Scripture requires a secret key to decipher the locks on the gates of Heaven that only their interpretation of Scripture can provide will have a lot of 'splainin" to do, assuming they even get an audience.
LOL I do not follow a religion of passed off keys. Peter's words are the key, and require NO decipher. There is only One who has the key that opens or closes, and it is called the Key to David.
