Did he? Others have very well explained this before. There is nothing incumbent in the keys that every other apostle doesn't also demonstrate in their ministries. If it was given only to Peter, then why is it that All the others have the Keys?
What, exactly, are the "Keys to the Kingdom"?
Wouldn't they have to be something that unlocked the kingdom.?
Wouldn't that denote the fact that the kingdom was locked closed?
Wasn't man locked out of the kingdom...denied commune with God because of sinfullness, until the sacrifice of Christ?
Wouldn't the "keys" to the kingdom be that the messiah had come and that his sacrifice was going to open the door?
Mat 16:19 And I will give the keys of the kingdom of Heaven to you. And whatever you may bind on earth shall occur, having been bound in Heaven, and whatever you may loose on earth shall occur, having been loosed in Heaven.
Key 1: Jesus confirms that he is the messiah:
Mat 16:20 Then He warned His disciples that they should tell no one that He was Jesus the Christ.
Key 2: Jesus tells them what needs to happen in order for the kingdom to be opened:
Mat 16:21 From that time Jesus began to show His disciples that He must go to Jerusalem and suffer many things from the elders and chief priests and scribes, and be killed, and be raised again the third day.
In other words, Jesus, gave (revealed) the keys to the kingdom.
What else could the "keys" be and how could a mere man hold them?
