That sure does not look mainstream to me. As far as homework is mentioned, homework is not needed when a simple demonstration of fact is sufficient to disprove an allegation. Matthew 16 is clear evidence that Peter had an idea that Jesus would rise from the dead. A complete refutation of your false assertion. Nuff said.
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 up on the third day. Peter took Him aside and began to rebuke Him, saying, "God forbid it, Lord! This shall never happen to You." (Matt. 16:21)
It looks to me like Peter was in denial about Jesus suffering and being killed. (Why would Peter have "an idea that Jesus would rise from the dead" if he didn't think Jesus was going to die?)
A complete refutation of your false assertion.
Complete refutation? Wrong on both counts.
