1. The Roman Catholic Magisterium claims that Jesus gave singular, ruling, infallible authority to Peter alone.
The primary text used to support this is Matthew 16:18–19, where Jesus says, “You are Peter, and on this rock I will build my church… I will give you the keys of the kingdom of heaven.” The argument assumes that this establishes Peter as a supreme monarch over the Church, and that this authority continues in a single line of successors. But the text itself does not say that. Rome ASSUMES this into the text. It does not say Peter alone holds the keys in perpetuity, it does not say he is infallible, and it does not describe a transferable office.
In fact, the authority to bind and loose is later given to all the apostles in Matthew 18:18. In John 20:23, the authority related to forgiveness of sins is given to the gathered disciples, not to Peter uniquely. So even if one grants Peter had a leading role, the New Testament presents apostolic authority as shared. The structure is collegial. There is no language of supreme jurisdiction or singular rule over the others.
When you move into Acts, the narrative reinforces this. Peter is prominent in the early chapters, but prominence is not supremacy. In Acts 15 at the Jerusalem Council, Peter speaks, but so do Paul and Barnabas. James appears to render the final judgment. The letter that goes out to the churches says, “It seemed good to the Holy Spirit and to us,” not “It seemed good to Peter.” That is conciliar authority, not monarchical authority.
Paul’s confrontation with Peter in Galatians 2 further complicates the Roman claim. Paul says he opposed Peter to his face because he stood condemned. If Peter held supreme, infallible jurisdiction over the universal Church, this moment becomes structurally destabilizing. Instead, Peter is treated as a fallible apostle who can err in conduct. The text does not present him as an untouchable ecclesiastical monarch, or a monarch at all.
One more point that often gets overlooked is how Peter refers to himself. In 1 Peter 5:1, Peter writes, “So I exhort the elders among you, as a fellow elder and a witness of the sufferings of Christ.” He does not call himself the supreme bishop of the universal Church. He does not appeal to singular authority over all Christians. He identifies himself as a fellow elder among elders. He urges them to shepherd the flock of God willingly and not domineering over those in their charge. That language cuts against the idea of a monarchical office concentrated in one man. If Peter understood himself as the supreme, infallible ruler of the Church, this would have been the natural place to clarify it. Instead, he presents himself as a co-presbyter, modeling shared pastoral leadership rather than singular supremacy.
Now move outside Scripture and into the first two centuries. This is where Rome’s case becomes even more difficult.
Take Clement of Rome, writing around 96 AD in 1 Clement. He writes to the Corinthians to address disorder in their church. Roman Catholics often cite this as early papal intervention. But Clement does not write as a supreme bishop issuing a decree. He writes on behalf of the church at Rome, not in his own singular authority. He never invokes Petrine supremacy. He appeals to apostolic tradition and Scripture. His tone is exhortational, not juridical. If a fully developed papal office already existed, this is the moment you would expect him to say so. He does not.
Consider Ignatius of Antioch, writing in the early second century. Ignatius strongly emphasizes the authority of local bishops. Each city has its bishop, presbyters, and deacons. He speaks highly of the church in Rome and calls it preeminent in love. But he never describes the Roman bishop as possessing universal jurisdiction over all churches. In fact, his model of authority is local and episcopal, not centralized in one global office.
