The Simon Peter sandwich

The technical term is the ‘Petrine inclusio’, which, in addition to sounding highfalutin, also hints at the absence of literal sandwiches (my apologies if you were expecting one).

The sandwich is this: Peter is the first and last named disciple in the gospel of Mark (1:16, 16:7) and in the gospel of Luke (4:38, 24:34). In John’s gospel, Peter’s inclusio is contained within that of the Beloved Disciple’s.

–From chapters 6 & 7 of ‘Jesus and the Eyewitnesses’ by Richard Bauckham
