Jesus and the High Priest's Saviour

We see a very strong christology coming through in the gospel of john. Jesus words in verses seven o nine, where he speaks about none of his disciples being lost, and his concern to protect his disciples show his commitment to suffer on behalf of them. The disciple who attacks the high priest's servant isn't mentioned in the other gospels, but here we are informed that it is peter. Peter sort of serves as a leading priestly figure among the disciples. And while jesus is being tried before annas and caiaphas, peter is denying jesus in the high priest’s courtyard. There's an important parallel and contrast being established.
