"PETER as Shepherd and first Pope: Scriptural evidence and the structure of the primitive Church make it absolutely undeniable that Christ chose Peter and that Peter was first among the twelve. Depending on the translation, Peter is mentioned 195 times. The closest is John (the beloved disciple) at just 29 times. The rest even less. Consider:
