I can think of one He should call obfuscator. Was Peter named Rock by Jesus?
Not keeping up with the thread? Jesus called him Peter then during the same exchange called him Satan.
Compare that to John 1:42: "Thou shalt be called Cephas, which is by interpretation, A STONE."
Back to Matt. 16:18. "And upon this rock (Petra)..." An immovable stone.
So if Peter's name means in Greek a fragment of a rock, and in Aramaic a stone, then we can get a pretty good idea how big this rock/stone was. Pretty sure it wasn't "immovable". But Christ, the Rock IS immovable.
