Get thee behind me Satan?

Strider:

Commentary on this passage in the Navarre Bible indicates that Jesus rebukes Peter because he is thinking like man (No harm should come to you, Master) and not like God ( I came to serve and not be served - and to die and rise again).
It shows Peter’s natural reaction to the prophesy of the Lord and in no way diminishes his position in the Church, any more than his not wanting the Master to wash his feet at the Last Supper.
Peter understands things like we do, until Pentacost, when he is given understanding by the Holy Spirit.

You took the words right of my mouth!
Jesus is teaching Peter that he must think with the mind of God and not give into the humanness of our own self interest (satan). Jesus didn’t care about Himself, His only job was to teach love and forgiveness and obedience to God the Father, etc. Peter wanted to put Jesus in the role of king (of the earthly kind), to give Him a place of prominence and Jesus wouldn’t hear of it.

Peter had not yet received the Holy Spirit at Pentecost. Looked how he changed; he went from foot-in-mouth disease to being a powerful messanger for Christ! Jesus was teaching Peter not literally calling him Satan.
