What kind of argument is this???? Have you gone off your medication??
:)
Inspired (by God... who knew the answer to this argument) Scripture was written for almost a hundred years after Jesus spoke those words. And all of those authors got it wrong? Or did they stop calling him Peter when Jesus said "Simon" (Which never ceased to be his name)?
If there was even the slightest possiblilty that this latest "argument" (to be charitable) of yours held any water, we would not see these inspired authors (including Peter) using "Peter" when they would have known that Jesus had "changed it back"
