Many Protestant scholars, however, reject this position, such as Craig L. Blomberg who states, "The expression ‘this rock’ almost certainly refers to Peter, following immediately after his name, just as the words following ‘the Christ’ in verse 16 applied to Jesus. The play on words in the Greek between Peter's name (Petros) and the word ‘rock’ (petra) makes sense only if Peter is the Rock and if Jesus is about to explain the significance of this identification" (New American Commentary: ).
