- Simon = Galilean disciple.
- Cephas = Judean/Jerusalemite pillar.
- Peter = Hellenistic/Diaspora apostle.
Also, no need to cite the super obvious passages or verses which identify, say, Peter with Simon (such as in the synoptic disciples lists, which claim that Jesus gave to Simon the surname Peter). Obscure ones which may possess independent value are more than welcome, but the obvious ones would clearly be, ex hypthothesi, later syntheses of two or three of these separate individuals.
Overall, what does such an idea have going for it? What would it help to explain (if anything)? And what does such an idea have standing against it? Does it create intolerable coincidences (of the sort mentioned above, for example, of two men being called "Rock" or "Rocky") or tensions?
