To suggest that such failure is beyond Peter is to forget the obvious fact
that all four gospels record what is perhaps Peter’s biggest failure, i.e., his
denial of Jesus after the arrest in the garden (Mark 14:66-77 and parallels).
It is rather unlikely that the denial of Jesus would be a fabrication.49
Nevertheless, Peter rose to be a prominent member of the early church, so
can we not consider the possibility that Mark 8:27-33 presents Peter
somewhat negatively without vilifying Peter?50
