Christianity spread from 12 men in a remote corner of the Roman empire without the internet (or even paper).
If anyone is not able to get the above link to come up (like me today), you can google "It is quite certain Peter spent his last years in Rome" to get it.
Yes, obviously.Was the spread of Christianity remarkable because of the lack of means of long-distance communication, or unremarkable because Peter and the others were able to write letters?
