To be honest, it does not really concern me whether Peter is called Rock, or little rock, or pebble, or whatever else. I believe what the Church has always taught, that Christ is the only TRUE Rock. Compared to Christ, Peter, like the rest of us, is not even a grain of sand.
My point is that whatever name Augustine called Peter, it is undisputed that Augustine believed that Jesus appointed Peter to be the first leader of His Church.
Somebody named Mark Bonocore wrote: It is true that some of the Church fathers do speak of Christ or of Peter’s confession as “the Rock” of Matt 16:18. However, all of these same Church fathers also speak of Peter himself as the Rock. This was not an either-or proposition for our ancient Christian forefathers, but a “both-and” proposition.
I’ll leave to you whether you want to try to disprove that statement. I got the statement from the following:

I'll get the run around if I ask; but can you see if ANY of your FR buds here believe the same way?
