Jesus didn't call Peter Satan bro...
He was probably speaking directly to Satan(the adversary) who injected the idea of Jesus not going to Jerusalem to escape death and ultimately Salvation in Peter's thoughts..
Peter just like the rest of the disciples didn't understood the fullness of God's plan through Jesus just yet.
which then of course, Satan took advantage of his ignorance and humanity...
edit/update gamay...for another possibility..
Satan means adversary.
Jesus might have been directly rebuking Peter for going against God's plan..
as we can read in Mark 8:33 "You are thinking not as God does, but as human beings do."
so satan in this particular verse could mean going against/being the adversary..or something like that...
pero i think ang second explanation maoy mas probable..
'cause Satan in the first place is not really a name but rather a title..adversary.
hope wa ra ka naglibog..LOL
