An investigation of the New Testament reveals that Peter is not just another apostle. Nor is he merely prima inter pares - first among equals. Rather, he seems to be deeply conformed to the work and mission of Christ. He is, as we would say, the vicar of Christ.
Peter’s name is mentioned 195 times in the New Testament – more than all the other Apostles combined.
