Thanks for your response. In reviewing the scripture passages cited in the thread you referenced, I find none that show the other apostles believed Peter had primacy above the them. It isn't overtly said. I do find Peter being rebuked by the Apostle Paul for hypocrisy (in Galatians) for not holding to the gospel.
Most of what is there is an attempt to collect data to show he was special - more special - like the counting of the number of times his name is used. While this shows he was a central character and person in the scriptures, that kind of thing does not teach what you referred to.
Are there any specific scripture passages you can point me to that overtly teach Peter's primacy among the Apostles? I would appreciate it. I am assuming that if God meant for Peter to be the main Apostle and the leader of the whole church, He would make it overtly clear.
I think you would have a better time arguing Paul was central. He had direct revelation, was caught up into heaven, wrote huge portions of the NT (some of which Peter said are hard for him to understand!), was charged with bringing the gospel to the gentiles (Christ's last charge to the Apostles in Mathew 28), and defended the gospel in Rome - the center of civilization at the time.
