I can't think of any web-sites off the top of my head...but I can quote some Fathers:
"The word 'rock' has only a demonstrative value - it signifies nothing but the steadfast and firm faith of the apostles." - St. Cyril of Alexandria--"Of the Trinity",4th Book
"Peter and John were equal in dignity and honour. Chirst is the foundation of all - the unshakable Rock upon which we are all built as a spiritual edifice." St. Cyril of Alexandria, in his letter to Nestorius.
"He (referring to Peter) had not the primacy over the disciples, but among the disciples. His primacy among the disciples was the same as that of Stephen among the deacons." St. Augustine--Sermon 10 on Peter and Paul.
"As soon as Peter heard these words,'Whom say ye that I am', remembering his place he exercised this primacy, a primacy of confession, not of honour, a primacy of faith, not of rank." St. Ambrose, "De In Som Sacr." 4:32
"But observe how Peter does everything with the common consent; nothing imperiously." St. John Chrysostom, Homily III on Acts 1:12
"To all the Apostles after His resurrection He gives equal power and says, 'As the Father sent me, so I send you'." St. Cyprian, "De Unitate"
"For neither did Peter, whom first the Lord chose....when Paul disputed with him afterwards about the circumcision, claim anything to himself insolently, nor arrogantly assume anything, so as to say that he held a primacy, and that he ought to be obeyed by novices and those lately come." St. Cypriam, Epistle 70 concerning the baptism of heretics.
There are others, but I am a bit lazy...
p.s. all this is quoted from "Two Paths" by Michael Whelton
